Got this board out of a washer. http://i60.tinypic.com/2vcjr7s.jpg
Was wondering how it'd be graded. Mid vs low. And if low, the led's appear to have gold on each end and a thin gold wire inside. Am I correct? http://i62.tinypic.com/nqyemg.jpg

Yep, LED's have Gold in them.
If you do them yourself, there is a method called 'Patnors method'. Basicly you put them all in a metal container and reduce the plastic to carbon over a fire.
Then pan the Gold wires out using a Gold pan.
Theres still Gold left in the dust and on the Copper leads. Thats a different method and the strongest acid we use on Scrapmetalforum is vinegar.
Its possible to sell them on ebay, probably the best idea.
I am saving the LED's up. But I am also saving up scanner bars from printer scanners, they have a row of LED's and about 250+ Gold wire connections.
I pulled apart a inkjet printer head and found a bunch of thick Gold wires connecting under the actual printer plate, the part with the rows of holes where the ink comes out. It had a Ali heatsink or mounting around it.
Inkjet printers are cheap, but the actul unit has a whole bunch of Gold wires in it, in all different places. LED's, scanner bars, contacts, cartridges, inkjet plate, optocouplers, IR LED positional counters for reading the holes in the plastic discs.
It just don't make sense to me, too much Gold.
Thanks eesa. So, safe to say all led's have gold in them? Or are there some that dont?
I've noticed too from taking apart a few scanners they have hella gold on the scanner plates. First one I saw glowed like the sun as I'm just starting to separate ewaste. Lol.
So, that leaves a question for the guys that know the board grades. Would this board generally be considered a low grade and taking the led's and ic's be no big deal? Or would it be a little higher and removal will devalue it?
im no pro but it should be a mid grade as its green on both side and does not have much on it at all. All depends on where you plan on selling it,
I toss those in my "does not compute" bin. That has green boards from basically all non computer type units. If I'm getting 2.00/lb for mobo then I'll get around 1.00/lb for those. I can take whatever I want off them as well.
