Depopulating Low Grade Circuit Boards
HTML-код
- Опубликовано: 20 авг 2024
- Buying low grade boards is too low value to handle, since my price is similar to current scrap steel prices, scrappers are best to just sell them to the scrap yard instead of building them up in large qty's to then bring to me.
To value add, you can semi-depopulate and take off the easy to sell copper, transformers & aluminium.
IC Chips can be sold to me.
So I decided to no longer buy low grade boards, only mid grade and above as well as the usual items like hard drives, RAM, CPU's and other gold recovery bits.

As a DIY electronics enthusiast, I see so many useful parts there.
Exactly, I don't mind saying I'm a circuit gypo, anything that can be reused
Massive diodes for the full bridge on that crt board surprised me. Not to mention inductors with heat shrink to eliminate hum I'm assuming.
@@DockterDoom me too, I usually get very crappy components from the majority of CRTs
Yeah I feel so sorry for the most of the useful parts that he broke them off
at least he can use any kind of heater plate and put the board on top of it that way he can salvage so many useful components
@@Muslim_011 that’s what I expected when opened the video.
I salvage components for hobby use, and I am drooling over the amount of good usable parts here!
The video is recent and maybe more arrange with this person to send some good stuff
You could also recover some components from the circuit boards. For example, I'd cut those diodes that are on long legs, those are higher current diodes which could sell to people that repair TVs and monitors, for example make a bag of 25-50 pieces for 3-5$ ... capacitors can be sold in bags, those old cheap ones from CRT boards could still be used by hobbyists in audio circuits and low voltage stuff... do a bag of mixed capacitors and sell it for a few dollars.
May want to consider solder pots, you heat up that solder pot and then just put the circuit board above the hot solder and you pull on the components to take them off the board.
You can get grab bags of new parts like that for dirt cheap already. And with a good living starting at around $40 per hour, you'd have to pack about 10 bags per hour or about 250-500 parts per hour.
This should be something covered by governments to pay people properly to process these boards so they can be disposed of in a responsible way.
If you don't make a circuit board like these into 20 dollars of harvested parts you are very dumb imho
@@greenfoam I agree that these are worth more than what he is selling them for. Selling parts for scrap metal will always be less than the value of a manufactured part. With proper equipment like hot air stations or infrared heating beds parts could quickly be literally just shaken off the boards. The only catch is that he has no way of knowing if the components work or not. It is too time consuming and definitely not worth it to test components. And even if they work long enough to pass a test they may not last long. Especially being tossed around and exposed to high heat while harvesting them. You can’t sell parts with such a high failure rate as individual parts. No one will buy one of something they need knowing there’s a good chance it won’t work. You have to be transparent that they are used parts and only some of them may work and sell them in bulk to make up for it. This reduces the value a fair bit. Also going to the effort of reading part numbers which often is hard to do and organizing parts very specifically based off of capacitance resistance values etc is even harder and more so not worth it. To make up for this you have to lower price again and sell it even bigger quantities. Since you are being so vague you need lots so people know there is a chance of what they actually want being in there. Or you have to sell it to a 3rd party sorter who will expect it cheap since they would have to go through the effort of sorting it themselves which is a really slow low profit job. So 20 dollars no. If he spent hours upon hours on each board then sure. But at that point he would be making significantly less than a minimum wage job and there would be no point to this. As electronics enthusiasts it can be hard seeing this stuff go to waste but it can’t all be saved. Also older ic chips often times no one even wants anymore because the products they were designed for are rare and not in use and people wouldn’t try to repair them anyway. Generic ic chips that are low transistor count with very broad use cases can be resold as a chip but high transistor count specialized chips are refined for silicon and gold which is a expensive process that is worse for the environment because of all the energy and hazardous chemicals it takes then just tossing them in a landfill. Definitely though he isn’t getting full value out of them but I don’t think 20 dollars a board. If he was setup like a retail store where people could look at his collection and chose things they want then be quoted a price I think that would be the most profitable way to do it but it could be hard finding the customers needed to do that. Would have to be in a very busy area in some place like china where there is l out a of manufacturing going on etc and many people are actually interested in that sort of thing and people make less money so it is worth it to them. China used to take most of our scrap. They don’t want it as much anymore though as they are desperately trying to become a first world country. Edit: I almost forgot. Actually listing and selling the parts online especially on places like eBay is already a very time consuming task and there are also shipping costs which devalue the parts and eBay takes a large cut out of what it already a very small profit margin. Plus lots of people would complain stuff doesn’t work and get refunded by eBay and you would lose lots of money shipping things and not getting paid and having to pay eBay fees and PayPal/credit card processing fees even if the customer gets refunded. Even if you put a disclaimer saying it might not all work people will try to refund it anyway. Even if it does work people may still try to scam you. They seller usually loses disputes. Buyers are always out first meaning sellers often get screwed over. Also it takes time to actually package stuff go to the post office or prepare it for pickup. It may sit places for long periods of time while waiting to be sold and when stuff finally does sell you have to sort through stuff again to find it.
@@jacobleeson4763 This is one hundred percent true
My humble advise: try to take components out of the PCB's in such a way to not damage it. Use desolder stations and suitable tools to do so. Some of these components are high quality, valuable ones and can be sold for hobbysts or students. You could earn a good amount of money by selling the components in small bags.
Greetings from Brazil! 🙋♂️🙂
Not worth the time unless you know specifically what you're looking for.
In part I agree, but you will never be able to guarantee that it works. How could you sell it?
@@almostdarkslide3851 youd sell a bag of a dozen or so of the same chips, people buy them knowing they are taking chances, that a couple might work
@@robertr376 that's acceptable, good answer.
Just imagine running a rapid desoldering rig... so many chips that could be sold for $1 each here in Australia but instead they're trashed for a few cents of gold here and there. The jaycar markup on those chips make them $6+ each new.
I've seen enough comments already, and I agree that you shouldn't rip the components out. Some of them can be more valuable than raw materials if they work.
problem is you still need to find a buyer for those chips and I don't think there's a huge demand for ICs from old VCRs or CRT televisions or any other common components like capacitors or transistors. There's a reason the boards landed in his hands in the first place and going out of the way and testing if an IC even works just isn't worth the trouble in most cases. Also, clean removal takes time, and time is money so any time wasted on cleanly removing a 24pin thru-hole IC that in the end won't sell just won't make sense. This is all ignoring stuff like paying for fees and shipping when selling those ICs too so this is just too much trouble for something that in the end gives very little return.
I know I couldn't believe what the hell I was looking at.
I’m willing to bet the effort to find a buyer for those specific pieces just isn’t worth the increased price
as an electronics designer, i see treasure; maybe you could try selling components in mistery boxes for people to make projects from them.
Great idea, I'd buy some
You have to feed the chicken gold to have it laying golden eggs, feeding it mlcc:s only gives palladium eggs. ;-)
Hejsan,, det är ju nog så bra med palladium ägg,, det är ju högre pris 🤣
damn, this is my dream as a hobbyist. have lots of scrap pcbs, and salvage all the useful components
Yessss! Ughhh, just dreaming about all those TVs with flybacks or some microwaves right now, :p.
Most of it is trash and worth nothing. All of these chips/transistor-likes don't even have public datasheets and are absolutely worthless.....

You can use a plate that generates heat, place the board on top and remove all the components. You can save so many components.
flip the board and use a heatgun. everything falls out.
That was so painful to watch. He's like the Doctor Kevorkian of circuit boards.
@@PhrontDoor or a dentist☹
Breathe deep. It's so good for you.
@@PhrontDoor yes... this whole video was painful to watch as he basically broke anything instead of heat-pulling the stuff
Thanks for the updated video Ben, it's great to be reminded of the value in these boards. At about 36 minutes in, the large double coiled donut transformer with ferrite inside, I give those a couple of whacks with the hammer to crumble the ferrite rather than unwind. I'm glad I've saved so many of my low grade boards, now to just find the time...
Ha, I see that happens accidentally later anyway, but still wanted to say thanks for the video!
In my area in the U.S., I can't sell circuit boards, even as steel. So I just depopulate them completely. I don't get a huge amount so it's just a relaxing thing for me. I can drink coffee and watch eWaste Ben videos while poking around on circuit boards. Sometimes it's surprising how much copper they can stuff into some liitle tiny component. I even pull transformers and motors apart and get the copper out. I know, it's probably not worth it but hey, I like taking stuff apart. I put stuff together for a living and that's hard so it's therapeutic for me. I'd even love to be able to recover the solder from the boards but everything I've tried so far seemed like it was going to produce too much toxic fumes. I'm about 3 hours away from Boardsort, near Cleveland but I don't get enough volume to make it worth trying to go there.
Same here. I’m in Illinois
Greetings from northen Sweden and a fellow scrapper.
Make it a roadtrip if it's "only" 3 hours away. I have noticed from comments many yards don't buy circuitboards so I am fortunate my yard takes them. They pay flat rate for circuitboards, doesnt matter if it's a board from a TV remote or a telecom board, quick math in todays currancy comes to about $0,30/lbs.
I do pickups from a whitegoods repair shop and supplier and a H-VAC company and an industrial electronics repair business,, I get my share of boards and I agree,, it's Theraputic to pick off the goodies.
Check with your yard about Mosfet, I get high grade wire price for them.
Stay safe and take care.
its absolutely worth it , You are a crucial link in the resupply chain
"I can't sell circuit boards, even as steel". There is no steel in a circuit board.
As a 30 years technician and hobbyist, i see many things recyclable on those bins. Men I envy you. if I can only offer my services to you I will remove all of those parts and make it useful again especially those LOW ESR capacitors. They are not cheap.
Nice long videos like this are just right when you’re hibernating for the winter. Thanks for the upload!
Its sad to see valuable parts being processed for gold by people with no knowledge of their value. They even process $100 worth stuff only to get $1 worth or gold.
I think time is a big one here, yeah its maybe $100 dollars if you unsolder it and test it and package it and list it and sell it and ship it and so on. Its super quick and easy to just rip it apart and put it in a bucket. I think your idea is valid too, just maybe for someone with more time to process it in a more delicate manner.
Its not $100 worth when its 100's of different parts he can't even test. If he had 1,000 boards with all the same parts on it, then yeah, at that point it can be worth recovering.
If the author of the video wakes up to sell old parts, he will receive much more money. Hello from Russia!
As always, great content. It is nice to see you get back to some educational videos as they are my favorite. Keep up the great work and have a happy new year.
DIY and project people are interested in those fly back transformers, probably misspelled it, big oblong cylinder with the big red wire, they are good for high voltage projects, ...
It would probably be worth someone's time to sell tv fly back transformers and lots of capacitors, project parts, stuff like that, off of the boards, seperately on ebay
I've bought random things like that myself, some things are hard to find and quite expensive new.
Ben my grandson loves to take all the Aluminium and Copper components off those boards. He really enjoyed the video. Thanks 👍👍
Ok I really wasn't expecting that chicken lol
You should definitely look into using a hotplate or heatgun instead, would save you a lot of time and energy removing items.
I love how the chicken was just chillin over there watching you haha 😂
Hello Ben, always a pleasure to watch your videos. your the person who inspired me to not only get into scrapping and melting metals but also refining. I would like to add that there is silver in the light blue m&m looking capacitors that low grade boards are riddled with. I know its up to every individual as what they are looking to get out of anything, just thought Id share my personal findings
i use to do that to re-use the components. i used a small butane torch. I did this back in the days when just about everything was through hole chips. I would heat the solder on the backside of the board then slam the board down over an open bucket face down.The downside was inevitably heating the fiberglass which makes a really noxious gas and some smoke.
Propane torch works really well!!! Have the board upside down, heat the back with the torch...the parts that are soldered thru just fall out with practically zero effort!!!
May I ask why you don't use a hotplate instead? This seems like a much harder (and wasteful) way to do it.
He's a caveman with tools but has yet to invent fire.
With some flux and a bit of lead. -edit: no flux
Dangerous fumes could be a problem though.
Yeah sure, use expensive energy to render a slim return to a solid loss :-P
@@stevendegreef93 Does this guy work for free? Because I don't think the cost of running some kind of heater setup would outweigh the time savings. He spends over 10 minutes on a single board that could be 1-2 minutes if you just heat it up and let the components fall off.
No workbench is complete without a Table Chicken. Great vid.
I always learn something new even if it's just learning to say copper or aluminum. Lmao
Dang id rather live near an electronic junkyard than a nice clean village
Im just a poor hobbyist teen who cant get components easily, and those boards right there are treasures
Hello sir , you sir have showed a whole lot that I didn’t know before and my buyer was taking for a low baller , and I was taking them about 300-400 lbs every six months now they’re lost I did find a new buyer but I do have to travel 3 hours away and will worth it but I do have to take double the amount to make the trip so now I take my time and go thought my mother boards ! Thank you 🙏 sir without you post the video which I started following you about 2 years and shark scrapper which we both live in the same state ! Thank you again
For what seems obvious for most of us, that was full of great information for the budding Microscrapper, though you did mention it,I would have shown breaking open a mosfet for the copper, as you say every little helps. Flybacks 😂 you know the pain.
Hello Ian.
Mosfet,, I get high grade wire price for them at my yard, quick math in todays currancy comes to about £2,50/kg.
Everything i ever build is was made by parts from already used PCB like this. As a student it was worth the time to desolder that parts with care.. I build lots of stuff with them.. dual laboratory power supply with case from garbage.. and it is still working almost 10 years without any problem... 20 kHz sinus,square signal generator.. still working... 300W amplifiers... etc...
And not to mention that most of those PCBs certainly work fine. Just someone threw them out because was lazy to put it to internet and send it to someone who would use it for another X years.... Im sad for humanity.... wasting resources and polluting nature...
this is not a waste of resources. if this stuff didnt land on his table it would go into landfill.
The chicken was eating the pcb bits lol
Awesome video, I especially like to get all the small coils and spools off of low grade boards. It's very easy to scrap them and they have surprisingly good value 😊👍👍
Киты давно научились в дросселях использовать вместо меди алюминий, так что переключай калькулятор, а вообще они используют сплавы- меди там нет)))
I really like these teaching videos. I think I will start doing my low grades like the removing copper and aluminum. It will be easy as I don't get a lot at one time my 50 low grade boards a week.
That chook though. It actually looks like the chicken enjoys the show.
In Sweden you cant sell boards as scrap stell,the yards here get to pay ""fine´s" if there´s boards mixed in with the steel
It should be same in all EU.
Why the hell am even watching this stuff and not even wanting to close it.....🤔
Ok i got to ask how many times has that chicken eaten scrap lol
Your videos are literally a mine of valuable information! Thank you for taking the time. If anyone wants me I'll be in the garage dealing with my massive pile of low grade boards that I've been wondering what the heck to do with 😄
In mid Canada and nobody buys boards. Our recycling of them only benefits one bigger processor.
That's us.
I started de-populating boards for copper/aluminum melting, then learned about the gold processing and started saving chips/fingers.
So therapeutic and a good way to get the needed vitamin D for health.
I could do those boards all day long here in the states but there are no vendors out here willing to deliver them I got the time but no product
Hit up any TV repair shops, or computer repair shops and see if they have any they will give you, just to make room.
That Chicken is going to lay a computer and a mouse.
You can use a sander to separate the RLC components from the motherboard. Sanding can save a lot of time. RLC circuit elements can be easily separated from the main board.
15:45 haha the chicken pops up. That was funny. I used to have 4 roosters and 1 chicken. I had to keep the chicken separated because the roosters were mean to the chicken. But they are fun to have.
Sretna nova godina Ben 🍀🍻
This is educational. Thank you for naming the components and materials.
Hi from the UK , i used to do scrap and done ok off it, but never used to bother much with circuit boards, but when i did i used to just save the copper and aluminium, and and some useful components , it is a lot of work what your doing, its more like a full time job, and a lot of time and effort ... it takes up a lot of space ... sometimes its better to cut your time and loose a few cents to at least give you more time to do the things that you like doing rather than having to do it ... mine was just a hobby for some pocket money ... good luck
I recently fixed my mechanical keyboard by replacing an 1N4148 zener diode, very easy to find on these old pcbs.
Those little push button switches have nice silver recovery on them
Many, many components still in good condition and totally functional so it's a good thing for the planet a business oriented to the reuse of them
I buy storage units at auction. You're gonna make me hoard worthless electronics so I can scrap them....like I don't have enough to do 🤣🤣🤣
Some of those ICs are worth hundreds of dollars today. Certain businesses or hobbyists may have old equipment that they need to fix. You could sell some of those components for a decent return.
Great vid, as always invaluable info, thanks Ben , wouldnt be where we are without these vids. :) keep up the good work
You make more money selling the heat sinks. They go for like $5 a piece online, $20 for 5 or so.
Of course, shipping may or may not be included.
Super video and info. Thanks
Very interesting video Ben 👍 surprising how quickly your yard filled up after your Xmas clean up
Hello Ben.
The yard I sell my boards to pays flat rate, doesnt matter if it's a board from a TV remote or a telecom board. Prices are good at the moment, circuitboards at 5 swedish krona/kg.
Happy new year. God bless. Kansas. Been watching too much RUclips. Cutting way back. But going to keep watching you.
How times have changed. In the sixties and seventies it was so hard to find electronic components in Australia. Rare and expensive with a large number of people into electronics as a hobby inspired by publications like Electronics Australia. Now few engaged in electronics as a hobby and there are parts everywhere, even high grade gold RF transistors and silver capacitors. Would kill for those in past times.
u can sell some of these on ebay , i can see so many boards that are worth some value and many are looking for these boards , i have a dead 40inch lcd tv cus i can't find its motherboard , local scrapyards have thousands of tvs but they don't have the time to find my exact model board , in here we have markets elling salvaged parts like those big capacitors might still have some life left , i buy many used parts from local markets cus they are way cheaper than new parts and for my hobby stuff which will typically endup blowing anyways its better to buy from scrap . and not pay 50 times more on lcsc or mouser for the part and shipping and wait. i just take my pocket multimeter and test the parts before buying them.
35:00 the easiest way to scrap them is to smack it with a hammer a couple times then pull apart and let iron parts fall out copper remains.. fast and easy..
That chicken is currently upgraded with about 64kB of memory just by picking random components...
Thanks Ben - it's always good to go back over the basics!
17:56 that's a ptc for the degaussing coil , when the tv is powered on it will be low resistance and then quickly heatup and go high resistance like a time delay relay .. degaussing is needed for few seconds
50:28 "Don't eat my crumbles!" lol
I'm amused by all the people saying that there are massively valuable parts here! I'm sure he would let you dig through his piles and buy the good boards for a dollar or two each. Then you can see if it is really worth the time and energy to de-solder, test, and then list and sell....and ship...these individual used components.
My eyes are bleeding watching so many valuable components ruined!!!111
This video filled a void in my knowledge of Boards. Very helpful!
I use a oscillating tool to remove those large IC's in seconds
Сердце аж заболело. И все ради меди, а хорошие детали в мусор, а я бы им нашёл применение ))
I find an oscillating multitool with a medium metal blade takes those IC chips off quick and easy. Also leaves the chip intact, which looks a little better when selling.
As long as your not hitting the board, that tool will atomize the board into very fine and dangerous to breath silicon dust.
That chicken has some SMD resistors and capacitors in his stomach
I too had a golden comet chicken. Most friendly chil chicken I ever had
Most of the people that are commenting on the way you scrap have not seen your other bids. They don't know you don't have the time. They don't understand the amount of time it takes. Keep doing it your way. It is the best for you.
Vids
Loved the chicken appearing at your desk
Great info, Ben! Always looking to learn more about differentiating between the different grades. I have a love/hate relationship with my low grades!
15:45....Just warning everyone, Ben's Cok pop's out & gives us a supprise. You've been warned? ha ha
Hi Ben, I use an old chisel and hammer to remove ic chips and other chips from boards !!!! I have a piece of Angle screwed to my bench put it up against their tap tap and off it comes
Put the mosfets and like transistors into a tin can and bake them on a charcoal fire they just go to dust and copper heat sinks no2 copper.
Oh my g... Many many boards i like this big loads mhmm yummy and tasty scrap 🤣 nice day friend in scrappin'
Good information, good presentation, but the best part of the video was the chicken.
@20:54 This chicken likes you, it seems. Perhaps you could train her to pick valuable tantalum capacitors from boards?
Minute 52. On ebay you pay about 50 ct a piece for those yellow polypropylene caps. Toroidal cores this size, not damaged, 1-5 dollar a piece. but anyway...
Awesome video. From UK. Very informative
Desolder back then front and remove part into separate containers. Sell bulk as-is to DIY makers.
Just put the bottom part of the pcb over the solder pot and wait for few seconds and give it a good smash all the components are off the pcb all cleaned up . Best way to remove the components it takes less time and effort and more value .
Good advice. ps why does the chicken want to come up on the table lol?
Fascinating...thanks for the video
You can desolder those ic, put in a bag and sell them on ebay. Probably it worth 10-20 $ per bag of 20 ic.
an idea that could help save a lot of time to those willing to depopulate, if they can get their hands on one, they could dedicate an old toaster oven for this, to throw their boards in there until it's hot enough to melt the solder, then quickly pick everything they want with pliers or something!!
Great and educational video that should help lots of people thank you for sharing your knowledge five stars my friend
I can see a lot of stuff there that cost a prety good amount of money, you need to partner with some one that repairs electronics, repar some stuff then sell on ebay, the rest u can scrap it.
Thing I forget often is: There's always more! Just get the bits and get it out the door!!! I remember when you only had some bins in the alley and now you look like a full fledged yard!
Wouldn't it be easier to put everything in a grinder then in a furnace to retrieve the metal?
Very good information.
Thank youx
even low grade boards have value as you just showed so a beginer could start there providing they have alot of time. great video ben!!!
The best part for me is when chicken jumps on the table 15:48
there is a lot of people like me that would happily trade old pc boards for analog tv ones, those old boards contain extremally rare elements that are no longer produced for 30 od 40 years
check in your local area for people like this
Hey Ben that blue rectangle at 21:20 is a mlcc so it's worth taking off
