Gold Finger Strip Boards from LCD TV's & Monitors

LCD TV's have a few different circuit boards, One is a little different, Finger Strip Boards.
With LCD TV's starting to replace crt tv's on the scrap heap, Finger Strip Boards will be a very common gold recovery subject because scrap lcd's are just about everywhere, these will be a good boost for scrappers who recover their gold.

I’m watching this video 5 years after you put it out .. and this is other Example of how you called something years before it’s time people are talking about these a lot now just like you said

[@bantalee2002]

take a jack knife or straight edged blade and lightly scrape the green off the microwires stretching along on the boards that are in between the gold spots and dots..bet you will see the fine gold wiring connecting to them.(some may have copper). people will be surprised to see how much gold is under the green coating. (except the larger green areas on the board that are flat blank looking). a valuable and good point when bringing to the table selling your scrap to a dealer. I cut some of the thicker-older pc mother boards in half..used my jeweler's loupe, looked at the cut and was enlightened to see layers of gold wiring...more gold than what meets the eye that is for sure. I would be interested in watching you do a video,.putting the lab coat on and show us the process you use to extract the gold. Thanks for the video Ben..good education.

[@eWasteBen]

bantalee2002 I will do video's like that when I get set up right.

[@bantalee2002]

I will be waiting..good luck!

[@terrylindsey6955]

You should check out whats under them built up black spots ! i been finding pure gold under them!

[@robertwood3009]

Ben if I knew how I would upload videos on the processes I use May surprise you just how much gold is on the finger boards. Basically I use a hot sand bath to remove all the soldered on bits then a hot caustic soda bath to remove the solder mask giving a clean board to process

[@eWasteBen]

Robert Wood I would like to see that for sure, it's not too hard to load a video, maybe someone can help you do it?

[@americanrebel413]

Great video Ben! Thanks for sharing.

[@shaneyork300]

This is my 2nd time to see this video. Last time was almost a year ago and I was very new to ewaste. learn more watching the 2nd time around. Also I know very little about KZbin Channels but I'm starting to watch all of the commercials to help you Ben. This video was intense, might be cuz it was 2nd time, but there was four 3 minute commercials. That was 75% of your video time. I'm VERY HAPPY to do it if helps. I doubt you'll see a post from this far back (3 years) so I'll probably post something about the commercials in a current video to come. Keep the videos coming!!!

Ive really wondered what those little rectangular things are on the ends of those that conect to the pannel. Theyre on the ribbon cable but i cant tell what they are

[@reginacarroll8149]

Is there a plastic layer over the gold?

[@williamela3340]

Hey Ben, I was wondering how much gold I can expect from 15 pounds of boards as that is what I currently have

[@eWasteBen]

+William Ela Hi William, No idea with the finger strip boards as I don't know anyone that has processed them yet. it varies a lot board to board and how heavy the gold plating/flashing is, it probably won't be a couple years yet before enough people start processing them in large enough qty's to get an average recover rate.

[@pradeepchaudhary5996]

hello william now can you tell me how much can you expect from 1 kg of these boards??

[@bryancannon7729]

How do you clean the boards and get them to pure gold 99.999gold?

[@cladqueen8054]

Can you tell me about the electrical charge stored in the board and what you do to discharge? Thank you.

[@americanrebel413]

Clad Queen It should dissipate after a while, But if you want to discharge A board, I learned to take a screwdriver and short them out, Or even lay them on A piece of metal that they can make contact on, That should do it.

[@williamssunu1946]

i had copper after i precipitated instead of gold could that be posible

[@robertjackson6509]

[@produmpsterdiver5456]

[@perryseay480]

have you found a dlp chip yet? the ceramic ones? they are very nice i have only found 10 but very nice for gold recovery

[@eWasteBen]

+Perry Seay Yeah a few, haven't found a board mounted one yet and waiting for the new style projectors to be thrown out, they have 'em too now, projection tv's are just about gone around here so I won't get many.

[@rakeshkumarprajapati435]

+eWaste Ben Hi E Ben I want to sell strip boards of TV have much gold to recover. if you want to buy 10 kg kindly do let me know. kindly upload a presentation how to recover gold from strip boards.

How much gold in one kg

[@rodneysrepurposingrecyclin3821]

I have processed some with gold fingers. the amount of solder mask that ends up in the foils is ugh. I have found the best way to process the lcd boards is to depopulate them and crush them into -200 mesh powder. then either pan the powder or run it on a shaker table. All the epoxy left in the gold will cause problems. once it is all crushed and seperates it is very easy to refine.

[@eWasteBen]

+Rodman Lyons didn't think anyone had enough yet to warrant processing them, would like to see a video on how you do it, what do you crush them with?

[@rodneysrepurposingrecyclin3821]

eWaste Ben I outsource that end of it. I throw boards in a big bin after I depopulate them. When it is full I send it to a company that builds mining equipment. They run it through a hammer mill and ship me the powder. I mix the LCD boards in with all sorts of depopulated boards. I recover all the metals. I ran 4 pounds of them in a/p the epoxy from the solder mask made a mess. Can also crush them with a ball mill. Would take longer but it is possible.

[@eWasteBen]

+Rodman Lyons how do you separate all the metals from the powder?

[@rodneysrepurposingrecyclin3821]

+eWaste Ben a sluice box. Which I made out of a corigated pipe. I run it just like one would in a gold mining operation.

[@eWasteBen]

+Rodman Lyons oh ok so your just going for the gold

[@ohraa1]

Hello ben, would you happen to know the difference between LCD tv's and LED tv's. one agian thanks alot

[@eWasteBen]

+Rick Flores They are both LCD TV's, The LED relates to the backlighting, so instead of having fluoro tubes all running along the back of the LCD, LED's have LED lights on the sides, no Fluoro's. So to scrap they will be pretty much the same because we don't go so far to get to the fluoro's or LED's. LED TV's are thinner because they don't have the little tubes through it so it saves space.

[@eWasteBen]

+eWaste Ben LED LCD TV's are still new so I haven't actually scrapped one yet, they should still have all the regular boards like finger strip boards because it's still an LCD

[@ohraa1]

thanks alot ben for the help once agian

[@perryseay480]

do you recover and refine stuff yourself? if so please help with mlcc'shave saved up a ton but havent attempted to recover cause im not sure if i can

[@eWasteBen]

+Perry Seay I will be but not for a long time yet, gold refining forum has some info on how to process mlcc's

[@rajendrasharma1740]

hello friend who have led lcd strips scale old i am interested to but it

[@FollowMe2aMillion]

Hey Ben, I love your videos. So I have been studying almost two years and just recently doing recovery on fingers. While I have not tried it, I was thinking that a quick way to process these items would be sand bath and then dipping in HCL and bleach like you would ceramics. Whats your thoughts, thanks, Mike.

[@eWasteBen]

Mike McKinster Hi Mike, Thanks. Yes I think your on the money there, sand bath and process like ceramics. Once the boards are clean they could be processed just like you would any other plated item, so long as the gold is exposed you should get it all. I'm still accumulating stuff and am at least a year away from refining myself so haven't studied the subject much yet, over at scrapforum.com.au we're talking refining at the moment too and your welcome to pop in and discuss the subject further if you like.

[@zachlafave1914]

do you remove the ic chips to process?

[@eWasteBen]

+Zach LaFave Yes, all the items that come off easily like IC Chips, Flat Packs, MLCC's etc all will get processed in some way to recover the PM's

[@scraperLT]

7 years later, these boards cost 8 EUR/KG

[@rakeshkumarprajapati435]

Hi all I have strip boards in 50 kg quantity. is there any who can buy these strip boards

[@rodneysrepurposingrecyclin3821]

I don't want to hijack Bens thread here. Ask ewaste Ben first.

[@eWasteBen]

Finger strip boards from lcd tv's are not worth much, I pay 85c kg

[@rodneysrepurposingrecyclin3821]

+eWaste Ben that is a very fair price. I pay 35c per pound.
