- Discussing motherboards for precious metal recovery, part two will get to actual depopulating boards but I felt I needed to discuss my thoughts on pc, laptop & server motherboards first.
Stay tuned for part 2, Keep Scrapping & Have Fun!

You can see the difference in you from the beginning, back in 2015 to this video. You've researched and educated yourself about most of the components of the circuit board. At the beginning you were taking all the IC chips and now you have 5 categories or more for just IC chips. Plus so much more!
Thank you for the research you've done for yourself and us.
Great videos! For impatient guys like me, listen to this on 1.75X speed. Ben can still be clearly understood.
Thanks Ben - another good discussion. At this stage, I'm kind of aligned with you. I remove the CPU, Al Heat Sinks, and some of the BGA's, IC's and flat packs. But this is because of how my yard grades boards: high, medium and low. A partially depopulated mother board is still high grade. So I pull what is quick and easy and move on. I usually take the bigger MLCC's and Tantalums as well. And of course the crystals - because...who knows.
Ben in 2018, palladium will be equal to gold soon! 2022.. palladium $2556 oz gold $1758 oz glad I've found this channel! Big props man, love the content.
Wish I had seen this yesterday... I mixed about 20 boards of those dang bronze pins in with my other little bits of gold pins...
After total depopulation, followed by stripping the resin with hot lye, copper recovery from the boards is easiest by using copper sulfate reverse-electrolysis. You can set up quite a few boards in a big old fish tank or plastic tub and run them all at once.
How/where do you acquire so many boards? Right now I only get them from the side of the road. Do you have a deal worked out with local shops?
What to do with your base metal waste solns: precipitate with carbonate! Most transition metals will just fall right out of solution as carbonates!
Then, roast them at high heat and they'll decompose into oxides (some may totally reduce to metal if the heat is very high).
At that point, you have enriched transition metal oxide, which is basically high-grade ore some refiners will buy if you have a pile of it. They'll test it with an XRF spectrometer to determine the composition and value.
Tin and bismuth are the main problem metals. They form insoluble goop in nitric acid.
Always clean components off with HCl first. For brass-containing parts (which have tin in the alloy), use HCl with 3% hydrogen peroxide and aerate for at least a full day to totally dissolve the base metals. The tin and bismuth should remain in solution by this method, then you can filter and refine the solids with all the precious metals.
Thumbs up Ben..Be extra aware of the relay's and switches.
It is more fun to try it mate.
Nice Video..... Nice work ...! Great .. !
Spoiler... He doesn't depopulate anything in this video, but spends 45 minutes telling you to sell your e-waste.
hi bro,can i buy depopulated computer boards from you?
You've said things that needs to be said. I am saddened when I see people just going for the gold and trashing everything else. Before I get serious I will have a destination for everything removed. Hopefully I will get to recover the copper embedded in the board. I still have every board I've depopulated.
Right now I'm just pulling pins while watching youtube. I live in an apartment so I can't do any recovery. Next few months I will be looking for a nice private place in the country to set up shop. I'm looking at all aspects of recovery not just the precious metals. I really think its doable on a medium scale. Just got to define the processes and have an outlet for everything. I'm even looking into grinding the plastics and forming tiles or landscape blocks or something. Its all about the research and knowing what you want to accomplish before you create a mess you don't know what to do with.
@@opiewanau6303 Wow man! That is awesome! Im exited for you
I even try to recover all the aluminum. When you know as much chemistry as I do, EVERYTHING can be used. You just have to get the right series of reactions set up.
Ben, folks keep fixating on the color of the motherboards. The color of the solder mask is just a choice. The greatest metal weight in the board is copper whether the board is green, blue, tan, and so forth. For cleaned off motherboards I can get $1.85/pound or $2.55/pound for a populated one (they want CPU and at least minimum memory). For me at least it would be beneficial to clean off motherboards as I only do this to burn time when I am board. On the PCI slots, I always thought these were nickel plated with gold. The tiny amount of phosphorus wouldn't make for high quality electrical throughput.
I would never take yield ratios seriously as they are horrible at best. I have only seen one attempt that had face validity. This guy hand several chip models with nice quantities of each. He took a known quantity of each model and processed them together. He then calculated his expected result for the remaining volume.
I scrapped a few laptops and didn't know I should take them apart
copper lid in bga chip still constins bonding wires. But the copper is heavier than plastic and reduce the value per kilo. and often the copper is magnetic in bga chip
Hey Ben! Great video as always. Would it be worth taking some items off the board like the bga chips or high yield mmlcs and than sell it as a mid grade board?
yeah that would work on some boards but not motherboards as they usually only have two
mlcc's can get away with to most buyers, not me though :)
U well right palldium alot better price now over paltium
Over 90 metals on the periodic table and yet so many scrappers focus solely on gold recovery.
Ive saved up a bunch of misc. metals that aren't gold but I can't properly id any of the metals so I'm not sure how to sell for the best value. Like I don't want to turn in a whole bunch of platinum not knowing what it is and getting paid silver prices.
Hey Ben do you no how I will find a scrap yard that takes waste I'm in Sydney and I like doing my scrap
buyequip
Platinum used to be the most valuable overall.
No one will buy boards in Sweden privately for scrap. Some scrapyards pay average price of about 20cents (US) per kg for ANY type of board, even telecom boards. So I have depopulate everything or loose everything. Least they buy the stripped boards at 20cents a kg.
It sounds like a business opportunity for somebody with a bit of cash. Why can't you become the middle man?
no one buys circuit board in my area, i have to depopulate almost every component for secondary market sale
Hey Ben when you sale the boards will they separate high,mid and low grade boards? Or do you have to before you get there?
👏👏👏
Boa noite ..eu gostaria de saber se embaixo da tinta das placas do CPU tem banho de ouro?
Hi Ben, when you described laptop motherboard, there is a lot of 8-legs chips which looks like IC Chip. Is it IC or is it something different, not worthy to keep? Honestly I am keeping them, because I keep everything which I am not sure about. I am also not refining anything yet, just collecting like little hoarder :) (I don't have space to keep boards, so I take what I want and then I sell the rest to scrap yard, they pay fair even for depopulated boards)
N & P Mosfet, can have any metal as oxide but nothing really worth it, mostly just silicon
great👍
Hey man, I noticed that you posted to /r/silverbugs a little while ago. Have you ever gone to /r/preciousmetalrefining? There is a lot of good info there even though it is a slow and subreddit.
anyway, i love your informative videos. Keep up the great work.
furnace ????
We get our best money for scrapping mother boards here in the U.S.A.
Is anyone looking for 1990s cd rom
Boa tarde .. gostaria tanto de entender o que vc fala ..pois aqui no Brasil seus vídeos são importantes pra mim
Tem a opção de tradução. Qual a sua dúvida?
Eu não consigo por no tradutor ..eu queria saber se embaixo da tinta da placa do CPU tem banho de ouro
Raríssimas placas tem ouro por baixo da tinta. Essas placas-mãe não tem.
Entendi.. muito obrigada pela atenção me chamo Cristina
Cristina, se tiver mais alguma dúvida entre em contato. Meu WhatsApp (85)999265650
Hey Ben, I'm starting a small electronic scrapping business. Do you have any tips for me?
research and test everything you bring in before you scrap it
Ik. Iv been scrapping on the side and refurbishing predominately. Its surprisingly lucrative.
what is a good process?
any recommendations?
if your in a desperate situation and need the gold from your ic chips cpus etc... just sell it to a refiner they usualy take about 25 - 20 percent of gold and you get the rest
Very interesting thinking maybe just depopulate the whole old broads and keep everything I don't get nothing for the broads here Trying to learn how to get all metals not just gold and silver before I refined even saving the silicon chips people are making art or jewelry out of the wafer Thanks
The ebay is fucking expensive. I never buy e waste on ebay.
17mins worth of useless ranting about the metals backyard refiners CAN'T recycle anyways is stupid. If you're going to rant like that, make it a seperate video ffs.
Hater!!!
For real. If that's your only comment/question after the video then maybe you should watch someone different. If you truely just want help improve his content then a private message would be more acceptable
Waaaaay too much talking about the same things. No need to over-talk subjects to death
Some of us are dumb. So shove off
Just do it. Stop talking
