- Hello scrappers and planet lovers. In this video, I depopulate a circuit board that I got out of a computer monitor. Circuit boards are a re great source of precious and non-precious metals and are worth way more than if you left them on the circuit board and got ewaste price. I will show you how to safely and effectively identify and separate the metals in order to help maximize your profit and divert as much of the material away from the landfill as possible.
Here is the link to the computer monitor breakdown:
• Scrapping a crt or old...
i just recently got into scrapping myself and im currently doing micro scrapping to learn all the basics thank you for the informative video really love it !
Glad you find them informative. I really appreciate you watching and support. Stay well and happy scrapping
Hey Tin Man, Those transistors connected to the heat sinks are silver plated copper and also contain a small gold bond wire! Approx 0.02g Au/100gm and 0.4g Ag/100g.
wrong
Have you tried recovering? I have and numbers were as shown@@BigVik1111
He's not wrong.
Thanks! I know it is only a tiny amount but worth going after if you have several kg of mosfets.@@scrapping4shiba
@@BigVik1111... He is wrong especially when the video says they'll get #2 copper prices. The last time I saw a silver soldered breadboard was from a 1970-80s Mountain Bell Telephone internal payphone electronics. Since the atmosphere of the electronics will be designed for as humid or moist silver solder corrosion resistant over lead solder promoting moisture atmosphere corrosion are the reasons for design. There is a brightness in silver solder vs a duller silver look on tinned solder. Tinned solder is if the atmosphere is mostly dry weather electronics and not outside such as payphones. Lead solder is even darker. However, he would be correct with pins to IC chips, generally, in smaller electronics of cellphones. India RUclips videos show them not at all throwing MOSFETS into a huge collection of IC chips that they'll burn before grinding to a powder. A MOSFET would have wirey legs in that powder that they'll start chemistry recovery of the metals (silver and gold both start out the same) with nitric acid turning the acid bath the copper blue (green shows more lead). Gold, if a serious amount in the same looking blue nitric acid step will use hydrochloric acid and lyme extra steps vs silver extracting. Gold is pretty much sodium chloride and hydrochloric + more nitric acid chemistry (after Sodium MetaBusulfate or tree trump remover table salt uniodized to separate any copper by gold coming out of solution).
Just wanted to say you have the best presentation and personality of any scrapping channel. I am a former scrapper but still find your cost breakdown videos insightful. Recently I processed some finger card trimmings to show my kids the chemistry of it. Used hydrogen peroxide and cleaning vinegar to dissolve the copper that the gold is plated to. Wanted to take the process further and used electrolysis to yield back out the copper from copper acetate. Used a carbon electrode and pretty sure I ended up with vinegar again. I looked at the economic viability and electrolysis from copper solutions is significantly profitable.
Thank you for the comment and huge compliment!
You just recovered about 10 % of the value of that Printed Circuit Board (PCB). I make US$ 250,000 a year processing PCBs in my garden shed.
I spend less than 1/10 of the time on each board, compared to your old fashioned way, and I recover 100% of the values.
First the most valuable fraction is recovered: The solder. A two step hydrometallurgical process removes all traces of solder. From lead solder the Tin and the Lead are recovered. From lead-free solder the Tin, the Silver, and the other metals are recovered. Tin is worth four times more than Copper!
I never waste time cutting off any electric wires attached to the board. After solder removal, all wires and all electronic components simply fall off the boards. These components are easily sorted in the individual types for further processing in separate batches.
All wires and all components containing plastic are then pyrolyzed (in separate batches), yielding Raw Pyrolysis Oil, for later cracking into free petrol/gasoline, diesel and fuel oil. After pyrolysis the metal part of the wires are processed, without wasting time cutting off any of the connectors. They are melted and then electrorefined. The same process done is with the majority of all the other metal components (some require other treatments), thus resulting in full recovery of all base metals, silver, gold, platinum, palladium, ruthenium and tantalum, and lesser quantities of other metals.
Finally, the bare boards are processed for Bromine recovery, and separation of the thin Copper layers and the Glass Fibers.
Virtually every value of any PCB I get is recovered; nothing is lost. I process tons of PCBs a year.
Picking off a few of the components by hand will never make your rich.
Next level.
Solid resale item to snag off the old tube tv/monitor boards is the tall item in the top right. Its called a fly back transformer. Huge resale market as they produce insane voltages and are used in almost every high voltage hobbiest build. People want them undamaged so desoldering or breaking that section of the board off to keep the pins intact is best. Ebay ranges around 20$ for it alone. 👍
98 cents ones i have huge ones. From a 360 game and android boxes,computers. Aluminum.thx for showing. Great video.
Thanks! You get about twice what I get but still enjoy the process.
Last I checked, I was able to put the big black (top right corner of the board for most of the video) into my CBM bucket. Being out in the western canada, where I live we don't have all the categories you do so I have to break down things as much as possible to get every penny ;) Good vid bud, have a good day.
Yeo, that's my experience down here in the States as well. Sometimes I've had to break one apart to reveal the copper for the folks at the yard.
The white spools are easy to harvest, when you take the black mount of en putting a thin screwdriver in the shaft, you can unwind it easily then. I also take off the crystals, transistors and LED's for PM's.
Good day James Thanks for showing.
I like the way you show from start to finish
Glad you liked it. Thanks for the comment and watching.
I tend to clip the MOSFET wires and break off all the extruded and sheet aluminum heat sinks with them attached (I’ve seen some heat sinks that are nickel plated brass or copper, they are heavier!) Then I’ll remove all the screws/pins and copper parts, a bucket of them at a time with a drill. Sometimes you have to hold the nut on the other side with pliers while you remove the screw with a drill.
I have a bucket of silver contact relay switches I have to microscrap someday…👍
8 oz. extrusion ($0.50), 4.5 oz. #2 copper $1.05), etc.
5 oz. clean aluminum and some ceramic capicotrs and i.c. Chips I have for later.
Great video
Really well done video, helped so much. Thank you!
Glad it helped! Thanks for watching
That big black thing on the corner is a Transformer too
Those components are called Mosfets. #2 copper all day like you said.
Hi Tin man you do good work but it is always good idea to be wearing gloves especially when dealing with circuit boards as they have very sharp points the board should also be secured so components can come of easily
There’s a solution for that it’s called a fan. Recycling you expend more energy than you realize, and it gets hot real quick. 🐎✌️
the planet is doing just fine. i'm just here for the money
I do it for both. Although I won’t greet rich from scrapping
Do you remove all of the different color and shaped ceramic capacitors? I'm on the fence whether I'm going to mess with them or not.
Great Video!
There is a big difference between TIN and light iron tin shred. Tin scrap value is almost 6 bucks a pound around here.
These are just categories at the scrapyard: tin/shred and steel.
The big black ones are aluminum and I will scrap those. I have a separate bag with small aluminum scrap. I’ve never known what the substance inside is do you? ✌️
Cool!
I take the big ones off and remove the inside. Then put the aluminum in my mixed bag. 🐎✌️
Copper is king.
Yup, love my copper
Another question. Do you know what you can do with the heat elements that you find in electric grills and ovens? They are metal outside, but on the inside they are ceramic.
My yard takes them as dirty stainless steel.
I get stainless steel price as well.
Good for dummy loads for power amplifiers.
I’ve got about 20lbs of number 2. It all adds up. 🐎✌️
Oh yeah, easy and quick place to find copper for sure. 20lbs. is shaping up to to be a good payday
Hi Tinman, what do you do with the flyback transformer.
Good day What is a flyback transformer? Thanks
@@donvoll2580 That is the transformer on the print board of a CRT television or monitor. It is normally fully coated in black plastic, and one thick red lead goes to the backside of the tube. I think there is copper inside it, but I heard that some scrapyards do not accept them. Maybe they can be thrown in with the complete transformers.
@@TheDurdane Thanks
I put them in my tin pill because of the ferrite
There’s a little copper in them. Leave them on the board as breakage or maybe throw them in with copper transformers/motors.
Some of them little pins in the heat sink are aluminum or stainless
Yup, if magnetic then tin.
What is the difference between Canadian price and United States how much more do you get and how much left do we get
not sure of US prices since they vary state to state and even town to town, just like in Canada.
You looking sound like Tom from I Scrap App.
Quick question. When you're saying tin do mean shred, or tin is clean steel? Thanks.
these are categories at the scrapyard. tin/shred is any magnetic metal thinner than 1/4 inch like panels from washers, dries, microwaves. Steel is thicker than 1/4 innh
@@TinManScrapper shred can have bits of plastic mixed in I'm assuming. Is tin clean steel less than 1/4" or it's all considered shred?
Last time I handed in a few hundred lbs to shred and it was 100% clean.
I saw people throwing crap in that was half plastic.. that's why I'm asking.
I scrap for fun, not for money but I feel I wasted way to much time on my last load making it all 100% clean and getting shred.. am I wrong?
@@carpentryfirst3048 Yeah I too try to take some plastic off, but things like washer drums if they are coated with plastic I leave them on. So the yard does allow some plastic, but even they have limits too.
@@TinManScrapper thanks for your time answering my questions.
@@TinManScrapper hey, another question for you if you don't mind. Regarding insulated wire. The ones that have a single layer of covering are as you say 60% recovery. What about the ones with a single covering but also the soft fiberglass looking, woven covering on some of the ones in electronics. Can be any colour, and some have nice copper inside the wire but I don't wanna strip them because that fiberglass looking cover let's off a lot of unknown particles in the air.
Are those 60% too? It's another covering but it's very light and thin. Not sure of I described what I'm talking about properly.
2 cents per pound for E waist in Montana
Extruded aluminum is only 25 cents per pound. 😢
Wow terrible prices there. Thanks for letting us know. Stay well and happy scrapping
You need to find a new yard.
i am new to scrapping - where would I go to find all these all these computers & all other types of stuff I can tear apart ?
Garbage day is the best place as people throw everything out. I always find some type of scrap on garbage day. You can also find a lot on non garbage days as people are constantly throwing things out
Tell friends as well that you are getting into scrapping. I have had tons of friends, neighbours, and coworkers ask me to get rid of their appliances and electronics
hello!
I always remove the plastic. 🐎✌️
Can you make a poster with pictures of the part and it's value like #2 copper, silver tip. And put them on sale.
Problem is prices change often.
Not prices just to identify what parts are Scrapible, there makeup, and a picture. So I can look at the board and know what I'm looking for.
I have separate videos on each metal and how to identify. Look up “how to identify aluminum and stainless steel”, “scrapping brass”, sorting copper, micro scrapping how to sort, etc@@leroyrunk4422
Is there not a board buyer where you live? That one would go as a power board which would be way better than just ewaste price.
Unfortunately no
5 cents a pound?! Someone saw you coming! I get $3.18 a pound at my local scrapper...
lol, no, that is actually price for a lot of yards. It all depends on where you live as well. Love to see a receipt for $3.18 lb for this type of circuit board
Where does a guy take those components for cash redemption? To my knowledge, my local recycling center that I bring my plastic bottles and aluminum cans to accept electronics but i don't think they offer any cash value for them much less the directed components?
yeah, there are free drop of facilities that take electronics etc. If you want the money you need to bring to scrapyard. Atleast scrapyard will give you electronic weight price for doing nothing but bring the items in, or you can separate the items and get more value for the copper, aluminum, etc.
My scrap yard does not pay for e-waste :(
I get atm 185 a metric ton for shred,and 300 a nt ton for Vic rotors here in Nova Scotia atm July 2024.
Boards if u selling in Canada for pennies a pound .hold on to them till big yard in your area gets fully in into it n not ripping u off.you know they screwing u if they own a shredder.the shredder separates PCBs from any shred tossed into it n guess what they r doing with it....
I was holding my stuff that was higher dimes a pound on board sort for ten years.
I sold good chunk of my hoard that was in the 6 or less on board sort to my yard I deal with this week n got 2 grand from my little load .
Large soc mobos 4.50
Small soc 2.15
Dual soc 4.50
Hi grade 5.60
Mid 3.60
Low like the board he showing 30c a pound
Gold ram 25.00
Tin ram 11.00
Hdd with board .78 a pound
Look at board sort site price list n hoard anything worth a darn a pound.it might take u years before your yard starts taking boards for what they really worth or darn close sooner or later Iike mine .
If u r in cdn
Top tier stuff hoard it n send it board sort.the exchange rate will probably pay of the shipping.
Example old hhd boards/SCSI goes for close to 15 usd a pound.so why In hell u sell them for 5.00 or less.
Cell phone boards n so on.
So I save my top end stuff,cpu,ics,cell phone boards,old hhd boards,ram n so on.
They take up nothing for room really anyways.
Thank you for the comment. I agree. Luckily I do get better prices in London, Ont for circuit boards. As you said, hold onto them or shop around…it pays. Thanks and stay well.
Love your vids man, but please stop calling your iron/steel "tin". It has no place in a tutorial and could be confusing.
Your actual tin is the solder holding all of the components in place on the board and has a much higher value than shredder iron (as you well know 😉)
LME Tin price @ $11.50 per pound at time of posting.
that is the category at the scrapyards steel or tin/shred. As I explain in many of my videos steel is anything thicker than 1/4 inch and tin/shred all else that is magnetic
Where I live, they call it 'light iron' or 'mixed iron', I weighed some in end of October.. I got paid £135 per tonne, about 10 cents CAD per pound.
Ohhh you made $3.75 cents lol
hey better than the few cents I would have made bringing in as ewaste
@@TinManScrapper hey as long as you doing 5-6 hour still make 20 hr cash just depends how many you can get hands on everyday
Btw idk where you from but scrapyards around Dubuque Iowa where I'm at give you between 8-15 cent pound for this aluminum capacitors irony Aluminum
.8 CENTS A POUND FOR TIN? if you take 2000(pounds) and multiply it by 0.08 you get $160 a ton!!!
tell me just where i can get $160 a ton for my tin!!!
im a 65 year old man and ive done scrapping since i was a child!!!
Here in southwestern Ont. Sarnia it is 8 cents and London it is 10 cents. Btw, when we refer to tin/shred it is any magnetic metal thinner than 1/4 inch so all shells for examples from appliances and microwaves. Steel is all magnetic thicker than 1/4 inch.
Stop with all “tin”, it is not. I will allow steel, but it is iron, not tin, man.
It is just the category at our yards here tin/shred.
Enjoy your videos.... just wondering if you could heat the spent boards to recover the solder ? Solder is expensive to buy, maybe there's a market ? Thanks
heating the solder makes cancerous fumes
@BigVik1111 lot's of people use solder, heat it till melting point.
