In this video I will show you how to build a dirt cheap fume extractor and how you can fastly and easily desolder all kinds of components from old electronics circuits. I will also talk about what I think is even worth desoldering and which parts you should avoid

20 years ago it was a challenge to get any high quality parts in Russia. We even scraped all the remaining solder off the boards we were about to recycle for further usage. Even some dead parts were carefully preserved and had some usage in some projects. Nothing was thown away. And today people just toss away perfectly fine top branded capcaitors, high precision resistors and perfectly usable PWM controller ICs just because it is a pain to desolder then pin by pin with no proper tools handy. What a crazy world we are living in.
Кирилл Рагузин It does make me truly sad. Sourcing quality parts when you live overseas is a complete pain in the ass. Don't get me even started on consumer electronics these days.
Кирилл Рагузин God bless Mikhail Gorbachev
Кирилл Рагузин It's easier to buy new part than to salvage old parts. Furthermore what is the chance that you will find enough scrape PWM controller of right type that suit your needs? Personally, I don't have lot of scrape electronics so i have to buy parts. In past i was scraping electronic parts mostly DC motors (never resistors and capacitors) because that was only way to get some parts. I could forget parts like servo motors, step motors, transmiters etc. Now i have eBay where i can buy parts that i would pay 4x - 10x higher overhere. It's not crazy world, it's only economy of situation.
Кирилл Рагузин They are probably like most and don't understand or care they just buy the latest trendy new gadget.
Mat Matej because it keeps your skills sharp and ready that's more of a reason to do it.
Desoldering components from stuff that was meant to be used once then thrown away is highly addictive
100% agree
I got a taste of desoldering components and I'm hooked!
I agree, i got 3 organizers filled with parts, and the best thing is that i dont use them that often lol
Some people can't go in a bar, or a casino; I can no longer go to recycling centers.
Last time I picked up a 46" tv next to someone's trash thinking I could get some components. Turned out the TV worked fine but the remote didn't. College students I swear.
lucky b*stard!
Some college kids are just overly spoiled by their rich parents. It's sooo unfair!
I'm not surprised. When I was in college I would dumpster dive at the end of every semester. You will now believe the stuff they throw away. I once found a macbook pro with a bad hard drive. For the price of a hard drive I had a less than one year old macbook.
@@cultclassic999 what else did you salvage from this dump ?
@@laurentl3410 I work at a university and it's totally true, college students throw away plenty of useful things. Mini fridge, microwave ovens, smart phones, scooters, bicycles, laptops, computers, backpacks , clothing and dorm furniture. They waste money like its water. They should clean up what they dont need and sell it or donate it so as not to waste resources and pollute the environment.
One thing worth (really worth!) highlighting is the environmental impact of "parts salvaging". Most of these components use rare materials of require substantial amounts of energy to produce. Re-using them has a massive positive environmental impact and as well as being a great example of circular economy - cradle-to-cradle, a holly grail of CE. Well done!
I agree! Electronics recycling can’t recover and reuse things like FR-4, ceramic, silicon, leaded glass, and etc found in electronics. Reuse of components is better. I also heard somewhere that it takes 70 gallons of water to make one IC
De-soldering and sorting components. Probably the most therapeutic thing you can do!
That's *EXACTLY* what I was just thinking
Sorry I didn't understand. Why therapeutic ?
Strangely enough, this is what I looked forward to doing on Christmas Eve for a a period in my teens and twenties. My parents would go out for the night socializing and I had the house to myself. Turn up my favourite music albums, get some soft drinks and pull out a stack of boards I'd accumulated for the past year. Most of it still ended up in the garbage years later, but the point was I was doing my thing with no one bugging me. (Oddball!!! LOL)
@@tuxxic For some, the process is relaxing. Speaking for myself, there is a satisfaction in retrieving useful parts from something regarded as junk. The process doesn't require intense effort. You don't have to think very hard. It requires a little attention, but overall it's a stress-free, useful occupation.
I agree. For some reason, it's relaxing and removes stress.
My dad was saving small mechanical and electrical/electronic parts more than 50 years ago and I'm still finding just what I want in his collection - definitely worth doing!
let me save you time coils, relays, heatsinks, capacitors, motor, switches, push button, transistor, screws, transformer
Voltage regulators
windows_x_seven why are you this salty lol chill mate
@windows_x_seven Tantalizing offer. I mean I can try, but the sheer size of them is intimidating.
@windows_x_seven did you just call your own nuts microscopic?
r/suicideByWords
"You may not save a lot of money ..." but you do the environment a small favour 👍 Every effort counts. And I also rescue all screws from old devices for some decades already 🆒
Good point about the environment! 👍
Screws are huge and useful everywhere.
@@cultclassic999 no, it isn't. The same time is better spent elsewhere for the same purpose. It's a ridiculous fallacy.
I thought I was the only one cheap enough to do this LOL!
You'd be surprised to see how many guys fund throwing electronics away wasteful! 😝 It's best to salvage!!
Finally, im not the only one
Ya bro Mee too 😂
I try fixing first, then salvage, recycle the plastic add the metals to the pile. I separate by type and take to salvage yard about every five years or donate to the Boy Scouts. As for small electronics I will save a few boards just in case you need a small part for a repair, also if you use a hot air station you can remove an IC easily.
I get 99% of my stuff from the side of the road or op shops
I realize this is an older video, but one thing you forgot to mention, as you desolder parts you are actually increasing your ability to sold at the same time. It is a reverse method, but you gain the knowledge about soldering in general. And you see how much or little heat it takes to remove parts that way. I used to desolder parts off of thrown out board decades ago and basically removed anything I thought I would need later on. And I did use so many of those parts to experiment on hobby projects that way.
When you are joining twin cable (like on your 12v fan), cut the wires at different lenghts along the able so they cannot touch each other. You only need one tlength of heat shrink over both at once as well.
FaCt
Stephen Low , good idea. I'll do that next time.
Life hack
And if you cut off the connector from the power supply cut the cable in the middle. So you can save the connector (with the rest of the wire) as well :)
@@alexstone691 LOL. I hate that term "hack" as it's used now.
One of my teachers in his classroom always has a pile of freshly salvaged boards ready for students to desolder. Also he has EVERY component that I or any other student could need 😀 from little resistors to big filter caps
no way!!! that's so cool!
@2:10 Tip: Since air is compressible, always secure filter media (or any obstruction) to the inlet side of the fan, not he exhaust side. By compressing the air against the obstruction you will create about a 15% decrease in performance. As a side bonus, your fan will also stay clean.
great tip!
Hashem Mehyar Thanks
And what if you do both the inlet and exhaust? Or will that just decrease the performance again?
@@SibaNL more
@@yosyp5905 Yeah, that doesn't really help.
It's worth cutting those wall wart leads a few centimeters behind the plug, instead of right at the strain relief. With some length left over, you can solder on to the plug and reuse it, too.

i made a fume extractor using pieces i salvaged from old PCs lol
A cheap hot air gun lets me remove any component quickly, including DIP's, BGA's, and SMD's of any size sweep off a board by the dozens. But the best way I have found to maintain a stock of components from old boards is not to desolder anything but the largest components, so the boards can be stored compactly, and then attempt to locate schematics/service manuals which will help me identify mystery components, like SMD capacitors which usually have no value markings as SMD resistors do. If I have the schematic in my library, then I know I have the board, and whatever good components are left. As I use parts from a board, I cross them out on the schematic. Boards with no schematic either get cleared off completely, or I will make a file with the board number listing any valuable parts.
QSL
Also it's good to picture the board and store it as your own components database. EXIF stores max 64KB, so you can add to it the characteristics of almost all components!!!
Well a little on the ocd side arnt we now
Hi-5 for 1 upping me I've been using my propane torch which can get a little too spicy for the board. I bet I could dial in my heat gun and be looking like I'm a pro at it.
@@GbpsGbps-vn3jy I wish I had thought of that; excellent tip! This beats digging through stacks of boards to do a random search.
When I was a kid and didn't have lots of money for desoldering pumps or other expensive tools, I used an old injection needle to remove complicated parts like IC's: just remove the sharp injection part by holding it against a power grinding stone for a couple of seconds until it is flush and voilá: just stick the needle over the IC legs one by one and heat it up with your soldering iron: the solder doesn't stick to the needle and pushes the solder aside. Very fast, cheap and leaves your IC's still working fine!
I also love to take electronics apart. I'm doing this since 7 or 9. I just have no idea what im looking at, but im saving all sorts of components and boards.
I'm exactly the same I collect and desolder old PCBs just because there's something very satisfying about figuring out how some random obscure component with no part number woks There's been some.... Interesting side effects
@@harrcorr216 Meanwhile I repaired my first electronic. I replaced a mosfet and I was very proud.
@@funkblack fixing things is far more rewarding then taking them apart I respect that
Personally, I do keep capacitors, resistors, ic circuits, and even diodes. Yes, they are cheap. Easily obtained online. Free shipping even usually. In fact I have new diodes and resistors ect. I have desoldered many resistors and almost always they test correct. I also just use flush cutters and clip out diodes with long leads. Just test them with a multi meter. Personally, I never had a problem with any of it not working. The value in doing so is many fold.
The question is what is you time worth for a 5 cent resistor?
Well, salvaging those components even if they are 5 cents is always good if you have the time
@@San-zi1ig not in the real world of economics. Most people have realities to deal with.
@@larrybud Every hobby is worth your time, is not about the money.
@@MastersPipe Everybody has a finite amount of time, is spending a couple of hours to pull a dollar's worth of parts really worth it, rather than spending that time creating useful stuff?
When you cut off the old DC plug from a PSU to re-use it, leave 50mm of cable attached to the plug so you can use a screw-terminal block with it - handy for bench rig-ups ;) A major advantage is that you can easily add an extra capacitor at the terminal block to see if your circuit under test requires extra smoothing or RF filtering.
Always salvage fasteners. Everyone needs a good screw at one point or another.

It smells like angry smarties to me 😛

First time watcher here. Im Just getting into electronics and I have to say thank you. Straight to the point, accurate, essential information...no fluff. Refreshing.
I've been doing this for many years now, and it helps a lot to get free parts. I like your ideas!
Great video. May I add, when cutting a plug from a wire, leave enough wire to reuse it. Transformer plugs are always worth keeping.
I use the sun and a magnifying glass to desolder parts to keep it green
interesting 😂
Hmmm I don't know if my eyes would like that . . .
i would think that would be hard because solder is shiny...
@@fungusenthusiast8249 Paint it black and use welding goggles.
@@guilhermetorresj is it true?
The random "saved screw" bin has helped me in almost every DIY project. Great video thank you.
Heh, kids these days. Bulk desoldering with a soldering iron? In my day, we took a propane torch and ran it across the solder side of the board while pulling off parts we wanted. When you get good at it, you can us a flame spreader to heat a large area of the board then whack it from the component side with a few sharp blows and the solder facing down. It almost all falls out then the components can simply be picked off the board. Fumes? Do it outside.
I've been doing that forever haha
Pssh. You used a propane torch? I throw it in my fireplace!
What about EXPLOSIVES??
Works amazing for IC’s. Just heat up a row and ply it up with a screwdriver. Repeat for other side.

I agree, I salvage parts such as what you mentioned as well. You never know when you might be pressed for time, and need a component to fix a device that otherwise you might have to wait days or weeks for new to arrive. Also a great way to remove suspicion of a bad part right away when troubleshooting. If the used part fixes it, then you always have the option of buying a new part if critical of using an aged part for the application.
What do I remove? EVERYTHING I can, including smd parts - I pre heat the board then a heat gun and using a soft brush, sweep the parts off the board to sort out later. Gradually going up in size until getting to awkward parts. Then it's a case of using a Dremel, cutting through the board around larger parts like sockets and transformers, then dip the board piece into a solder pot by holding the part (wearing leather gloves!) and within a few seconds off comes the board away from the part. Sometimes it's necessary to pull the board section off the component with pliers. For a large mobo it takes around 20 minutes for a whole host of parts. The sorting takes a bit longer, but I do a big batch at a time.
Just made the fume extractor and planning on doing some more minor projects. Thanks for the video!
Good info. I've used several salvaged components in the past to repair broken electronics.
I somehow got sucked into these videos through the youtube algorithm and now I'm hooked. But I don't even know what this hobby or profession is even called to start my own learning.
Electronics, not to be confused with Electrical work. The difference is scale and one is primarily DC and the other AC with some crossover in each. In a nutshell! Lol ...... once you get into it, be prepared to be hooked forever.
I felt like a hoarder saving old electronics for parts, now after watching this i feel better!
videos like this validate my electronics component hoarding. I should not be watching.
Good video. When I was younger I also desoldered every component from broken boards "for later". Now I remove only parts which I need, it isn't worth to waste time, electricity and solder for parts which you may never use.
Just use a propane torch on the solder side of the circuit board and they all fall out.
If you are looking for carbon filter but don't need 10yrs worth a pet store has it in aqautics.
@Demo but i don't have carbon windows
Doesn't the pet store just have carbon bits, something like Norit?
@@saltysoysauce954 What he means by carbon filter is carbon-impregnated pads, which are used for chemical filtration in most aquariums. They're usually thick enough and might do the job just as good, but some are too spongy to be effective.
@@SartBG Oh interesting, never saw those. Pretty good idea!
They are also used in vacuum cleaner air out..put? You can buy them from stores and they usually are "cut your own" type. Fanned cooker hoods also carry one, they are replaceable parts and in Finland super/hypermarkets sell them too.
Everytime i see one of your videos i am reminded how much we are alike. I do the same thing; i salvage everything i can and store it in a labeled box. Keep the videos coming. You are inspiring a lot of would-be hobbiests and teaching them the right skills in advance; which they would learn eventually.
U r always awesome Scott, it has been more than a year of subscribing your channel and it's always a pleasure to watch your videos. Cheers from Egypt 😁
Yay you sound super excited! Keep up the great work Scott!😁👌🔋
Usually you can desolder DIP ICs using a heat gun for the few that are worth keeping. After you've removed everything else you want to keep. While I don't desolder then in advance it happens from time to time I'll desolder especially SMD resistors but also other stuff. Usually the resistors are for replacing in stuff that has way to bright (usually) blue LEDs in them.
Thanks for the good content , I'll happily pledge the good work you do at, sharing your time to make these videos.
+patprop74 Thanks mate ;-)
I've made a similar fan for soldering and de-soldering. Thank you very much, your videos are amazing.
More videos like this, I love your projects but videos like this help give us the ability to learn
Wait soldering fumes harm you? I absolutely love the smell of it though :(
soldering fumes certainly is harmful to our health lol. i kind of like the smell as well.
yes the symptomes you get are like astmha
You can get AIDS from smelling it .............
you will know because your asthma will get worse. Just build or buy a fume extractor for soldering and let fresh air in every 30mins (winter).
That's because there are no lead fumes from soldering. The temperature is nowhere near high enough. The fumes are from the flux, which is a known carcinogen.
I'm currently sick as hell from not using fume extraction. Anything is better than nothing, but honestly your health is worth the $40.
+Crazy Hans Use a bathroom vent fan hook up a dryer hose and vent it outside.
+Patchuchan great kill the human race... very very extremely slowly.
i made myself one of an pc cooler (fan) and an adapter
I smell something and it ain't solder fumes
Yeah, I just have a window fan blowing out a window, away from me.
Danke danke danke genau so ein Video hab ich gesucht! Das + deine Soldering Tips sind Gold wert, tausend dank!
I just built a fume extractor today! Thanks for the video.
Thanks for another great vid! :D edit: Don't forget the environmental impact! Sometimes it's easier to throw it out but if it works and doesn't take two days to salvage save it for latter!
Great video thank you. some may consider using a microwave fan for the extractor it comes with its own housing and they're really powerful and have plenty of space on the housing to mount a switch. Here in the US they are shaded pole motors and damn near indestructible. Most refrigerators have two of them and bathroom exhaust fans are another source, those just don't have housings
Nice video! This is very knowledgable for someone who just started soldering 3 weeks ago! Thank you!
I appreciate what you are doing. Im doing thesame. I actually built a 5 channel amplifier using my old amplifier boards and salvage parts from other circuit boards.
Awesome advice, and very environmentally friendly thing to do :-) It's terrible how much is just thrown away.
even more terrible that people would rather throw stuff away than to donate it to someone who could use it. Hell id be happy if people tossed busted hardware at colleges for learning purposes but no... trash can is the only way the get rid of good hardware.
@@oceanbytez847 Laziness. It's not even legal to toss electronics in the garbage, but people do it anyway.
@@baruchben-david4196 its not legal to do a lot of things that people do daily. kinda like that unspoken thing where everyone always goes 5 mph over which drives me insane bc breaking the rules so easily just gets you in a mindset where other rules lose meaning and are easier to break as well. so essentially speeding on the daily sets you up for careless thinking that can result in bad driving. psych 101 on that mark. If i am known for anything it will be for saying that everything is reached in steps. The taste of black coffee, spiciness, law/ rule breaking, bending your own principles, ect. Starts out small but doing it repeatedly makes doing it again easier and doing something more severe easier. today it is tech in the trash. tomorrow it turns into dumping used oil in your own lawn (just saw someone do that yesterday in fact haha.)
I think mindlessness is a more dangerous slippery slope than breaking the law. I have the utmost respect for safety, order, and effective solutions. But sometimes the law is not that, in which case I will consciously and deliberately break the law, and stand by my actions if called out. IMO the dangerous part of being a scofflaw is not forming a habit of rulebreaking, but forming a habit of thoughtlessness. Every time a group of people I'm with attempts to jaywalk, I will call attention to the specific details of the situation, how close the crosswalk is, how often and how fast the cars are coming, and so on. In order to force the people to be mindful of their actions, and not just break the rules out of careless habit. I don't have a big problem with jaywalking (though i usually don't do it), but I do have a problem with mindlessly jaywalking in a situation where waiting for the crosswalk is a faster and safer solution
^ this is true
Basically, any part your can use is good to keep...but trust me there comes a limit to how much you can keep on hand...and no matter how much you have there is always that one part you need to buy...;-)
ALWAYS!
So true! xD It's usually the one you finally decided to part with! ;p
Love your videos mate. Excellent info for professional and novice
Used to do this with my Grandfather back in the late 70’s Although a lot of stuff back then was valves and massive caps, a lot less IC’s etc. He got me started in electronics as a hobby, which in turn lead to My engineering jobs and then to my IT works. Thanks Gramps you shaped my world and didnt even get thanked.
Hi Scott! What an awesome topic you have found for this video. I just dont have words to describe how close and familiar this topic to technicians from Russia and CIS. Truly heartwarming. Just like my comrades say below, our elder generations salvaged mostly all parts they could find, but for now its not quite right. And i talking about an electrolytes: they dont like heating and subject to bloating, regardless of quality. As a friendly advise i would suggest to avoid salvaging capacitors or at least use them in projects woth lowest requirements(HV cap are bad! I still have some scars after explosion) anyway thank you for the video!
My brother made one explode in the lab for science (they took their distance). One piece got stuck in the roof, so yeah, be careful with the big ones.
Nice vid, Imho it's also nice to reuse old components in order to reduce waste and contribute to a more sustainable maker community.
Your my inspiration to get my electronics lab going back up now that I have my own garage
Dude, you're awesome! God bless you and yours! Happy New Year!
Videos like this make me wish I had a work room/carage.
thank you mr greatscott. I remember my childhood memories! I always love to salvage dc motors and i made it as my generator. hahah mr great scott before when i was a child i just only dispose those special electronics component like capacitors and transistor! but i never thought they are so special so much. I got tears of joy again because you made me remember my dream childhood. to be an invetor and engineer! ? more power to your channel. have you do that when you was a child?
Great Scott I'm from Jamaica I've been fixing tvs alot of times I love watching your videos
My dad was doing this for years and reached me as a child to do it too. I'm so glad we did this because I can't count how many times we reused a salvaged part!
Is it okay to reuse salvaged component I mean, are there any lead poisoning or health issues about it
Awesome video! Everytime i see : GreatScott uploaded a video It is like christmas:D Because maybe i get to know something new or learn something new about electronics that i didnt know before!^^ In this video it was not like this because i love to desolder and take apart things since i was 9 or so xD Everytime, i was interrested in how electronics work! Because of your videos i know a lot and my physic marks are extremely good ( 1-2 ) ^^ thank you for teaching us way better than our teacher:DD

The Fluke model 12b is a fantastic meter. My favorite. The reason being that it has "z" function. It reads capacitors and coils. Good luck finding one.
I was just about to go buy a switch, you reminded me to harvest one from something old!
Thanks Mr Scott, I learned a lot about the bits and pieces soldered to motherboard and what they are for, there were so many that I never knew existed before, so . it was nicely explained for the non electronic geeks like me out here in digital space. Thanks. I too have collected boxes of old tat and electronics from here, there and everywhere because visually, they look so cool. I had them fixed, edge to edge on my wall but needed the space for more tat so put up 7, 10 foot long wooden shelves. Some of the older model PC's have amazingly engineered metal cooling systems built around their CPU's. When my local car doctor upgraded to a digital system I was given all kinds of amazing probes, tweezers and pump things with tubes, fans and lots of Steampunk fixings and light bulbs. I also keep the magnets, especially the neodymium flat ones near the hard drive reader mechanism and every microwave microtron magnets I can get my paws on to build the first working perpetual motion machine. Actually not because magnets lose their magnetism and I'm told it just isn't possible to make.
I didn't know abt the fumes being harmful ...so thanks for that
Your plug cutout technique is terrifying. What a waste of a good dc Jack!
joblessalex I was think the same thing LOL.
joblessalex i would say the same!! Ceramic capacitors and small transistors are worth to save... It will make you save kilometers to go to the electronic shop! I save also cables and some connectors. As he said "we never know when we will need it"
yahnsolo I always save the small transistors and ceramic caps. Electrolytic ones go to the trash, but the ceramic ones are definitely worth saving. I use my secret weapon to remove them all quickly. Blowtorch to the back of the circuit board and a pliers or big magnet to gently pull them off. Works every time. XD
+theLuigiFan0007 i also save the ceramic caps ,resistors,transistors and dip chips
***** Indeed. Especially when you find lots of a specific value or high precision or a unusual value you think might be hard to find if you ever need it. I usually can't save the tiny SMDs even though I had a small tweezers for handling them. They just get stuck in a blob of solder. I might try *****'s idea over a white sheet of cardboard once I get my oxyhydrogen torch I use to desolder working again. I need a new clear plastic tank and graphite plates for the hydrolysis.
I love taking apart old stuff because it takes me back in time to see how things used to be made
I just figured out your channel then i just subscribed, my gosh i just like to collect those component also, and sometimes i felt myself a little bit crazy when i just go googling to find out too. I do felt like I'm a trash collector but as you have said, we never knew when we may need them. Thank you for sharing your kind opinions and thoughts, at last i got a channel to watch. I just started out about the amplifier and there's so many of them, and then comes the led technology. Hope someday i may do my own video also. Best regards.
Years ago I fixed a CRT monitor just by replacing a simple resistor that was taken from a PCB of some electronic.
Hackermaaaan! :)
I got a cheap desoldering Iron that has a built in solder sucker. Its really good for desoldering. IC's just fall out on their own.
I built a wah wah pedal a few years ago from old home appliance circuit boards using this method of scavenging parts. I used to help a friend whose job was appliance repair, so any time we switched out circuit boards I'd take them home with me. Most of the parts were easy to find, I did buy some of the resistors and caps though, but it took me forever to find a good suitable inductor coil. The coil is the main component that gives the pedal it's particular "wah" sound. Eventually, I got one when we repaired, I think it was, an oven. I was delighted!
Even if it doesn't save a lot of money or I don't know what I'm going to need a part for, I find desoldering and salvaging parts to be a very therapeutic hobby. It's relaxing!
A quicker way to solder things is use a heat gun on the backside of the board for a few seconds and give it a good whack and the parts will often just fall out.
+Patchuchan propane torch works well also...
Sometimes the pins are bent over. and you should use a clothespin or something to help grip them to extract them.
DO NOT DO THIS UNLESS YOU HAVE A BOARD OF INDUCTORS OR RESISTORS!!! I used to do this and it heat damages the parts very badly... sadly it is the only way to get BGA chips off of boards though. The fumes are awful too because you are getting burnt board, solder, plastics, and other crud all at once, which is a HORRIBLE thing for your health
@@allurared9029 i dont think a soldering iron is much better, because it takes a lot longer
I raid my school e-waste and I'm able to source over half my project materials from it
Really interesting video. One of my students once asked me about a capacitor on a motherboard and I didn't know the answer. I brought it to the attention of the whole class and told them it was their homework for the next week to identify the part 😳
You are simply superb man! Love your efforts
Don't laugh, but I had three times the amount of trash pcb's here from servers to household crap. I just took a small torch lighter and took most useful parts of this way. Surely this isn't a great idea because of the intense heat, but it worked ..
It works if the components have long leads that you can heatsink on the other side.
Yep but the torch idea isn't good actually. Because the components reach a sudden abnormal amount of heat which will degrade the parts? Or cause failure after the heat was applied? Idk desoldering seems to be the best I guess.
put a fan on the other side to cool the components and you'd be fine. most of these components ain't worth it anyway so break a few won't matter and most importantly it save you lots of time. Just check each of them after so you keep the good ones and throw the others.
Yep. Silicon components are more robust than most think, and a hot air paint stripper gun is your friend. After all, the components had to tolerate pre-heat and wave soldering in the first place, and SMD parts need to tolerate reflow temperatures.

I just hang on to entire pcb and remove component(s) around the time I need them.
I never thought about solder being dangerous I’ve just started working with electronics a little bit thank you you maybe have saved my health!
i love your videos keep up the great work!!!
Thing I like to salvage : Everything except the PCB itself. don't turn it on TAKE IT APAAART
you can actually do nice things with bare PCB's. I made a phone case from one.
I would leave some cable on the plug just in case you need a plug in the future
I just saw this video again, and think it should be viewed by anyone starting in electronics. Very useful advices
I am not alone for sure. Thank you for your video, sir.
I think one of the things I regret most in life js saving these random parts from electronics. I haven't in over 50 years used any of these that I saved. I always end up buying the part that I need.All the time I've lossed I will never get back. Time is worth more than money
I think the point is potentially saving these items from landfill or incineration, and the benefit of reuse. Of course that didn't work out in your case though but at least you tried and now, later on, there are places to donate those components to to save them from needlessly being thrown away. Certainly when you first started to collect there might not have been the same places to donate those items to. Globally WEEE is a scandal and we are spending a lot of time and energy taking metal out the ground just to put it back in within a few years in an almost unrecoverable state.
Growing up in the 80s my dad saved everything electronic from the 60s on.. we used all kinds of things. Lots of audio circuits from old radios and stuff like guitar effects pedals, even a safe.. he was an electrical engineer so maybe it's different but I save stuff and use it all the time.. lots of connectors, lamp, voltage regulators, switches and jumper wires.
you can never have too many of the basic parts (screws and other random stuff) if you think you have barely enough you don't have enough

Once you have more than you'll ever use, you have too many.
@@ionymous6733 Maybe so... But how do you know when you have more than you'll ever use? Having a ton of extra parts may even encourage you to try something you might otherwise not try...
Really interesting, I've been collecting and desoldering for a while - I'm building up a rather large microswitch collection for some reason...
Makes sense. I've been getting into the idea of electronics design. This is a good way to save some money and as well have parts on hand at all times.
2:02 most fans have an arrow indicating the airflow. Just a tip, and only for a minute :))
I've got a number of fans here and none of them have this arrow. It seems like they're just becoming less and less common, maybe to save cost.
If your fan does not have an arrow indicating the direction of airflow, you can always reverse the polarity of the power to the fan.
Borrow parts from your TV for a few days then solder I’m back on lol
Me too! I hate throwing away old electronics and will always take them apart for wires and such other parts. The amount of good condition screws you can get is amazing.
I used a fan to blow away the fumes, never thought of this. Great idea.
