OK, with IC Chips. Some people pop out the removable chips, some people don't, but NOBODY takes time to remove the soldiered ones. Is that right?
thanks!!

Removing the removable chips is a regular practice with most e-scrappers. The ones that are soldiered on the boards are a pain to remove and it can be toxic. The practice is known as "sweating" and it is a nasty business to say the least. The smell that comes off the boards when they are heated is just awful and toxic as well. Best to leave the chips on the boards unless they are removable. Just my opinion.
I snap mine off the low grade boards. the local yard to me that buys low grade boards only pays $.05 a pound and they dont care if they are all broken up and removed of the good stuff. So I take all heatsinks, motors, and IC chips I can. To remove them I just snap the board close to the IC chip then take side cutter and clip of that sides soldered pins then just bend the chip back and forth till the other side releases. Takes like 10 seconds.
Do you sell them at that price? We don't have yards here that buy e-waste, so all my boards (before knowing Easyrecycle) went as shred...Why take a 5 cent hit?Quote:

I believe he was saying you should toss it with your metal shred, since it's paying around 10 cents a lb.
Yeah I was going to do that with my next load. The yard I go to just lowered the board price to 5 cents this week. they use to pay 10 cents so thats what I had planned to do with it next time. thanks though didnt kow what I was thinking.
That's what I meant.Quote:

Thats what i was talkign about. Must e waste buyers dont like you depopulating the high grade boards and will downgrade them if they are depopulated. On a second mote I called my yard today they said they dont take low grade boards in the shred pile. If they catch you then you get banned from the yard.
That's silly. But hey, every yard is different.Quote:

What does IC stand for?
The removable chips I take off we refer to as E-Proms...
Thanks.
IC=Integrated Circuit
http://en.wikipedia.org/wiki/Integrated_circuit
I believe it means integrated circuit....
T.U both. :)
...these things then :)

Torker, those are transistors.
HERE, is an example. And you can use a sharp razor knife and slice thru the legs that are soldered down and they should lift right off. Don't know who buy's them tho,,, :confused::confused:

Most of the chips in the picture posted by Torker Man, I always thought were "power" transistors. Recently I broke off the ceramic off one and hit the metal part with an angle grinder. It appears the metal part is brass. I am wondering if my assumtion is correct and if there is anything of value in the black/ceramic part?? Thanks to anyone who can enlighten me, Mike.
Yes the backs are brass, have been for about 20 years I've been working with them. The black parts of them are a form of Bakelite with diodes and resistors smashed down into a really small package. They can be power transistors, or voltage regulators, or probably 10 other things they do,,, Even the CB Radio's I used to repair uses them for final power transistors for output.
Thanks for that. I can at least recover brass from them. Is there anything of value in the black part? Sorry to keep beating this one to death but its been a question in my mind for a while and this forum seems the best/easyist place to get the info, Mike.
I am buying the IC Chips for 3.80-4.00/lb even with the current wacky market.Quote:

we remove the socketed style and remove from lower grade boards using a small hammer and chisel. We are currently getting 5.75 - 6.00 per pound on these but it does take awhile to get a pound
Could you use two metal tubes to 'cookie cut' the chip out?
Theres no buyers of circuit boards around here.
Just thought I'd cut that bit out & fill a box with them & save them up..
use a flathead screwdriver, lay it paralel to the ic a sif you were tring to get under it, and gently tap with a hammer
Still confused on what are on boards, but I guess I have a board that has what looks like gold transistors, it came from a 60's-70's model school record player. Is it possable that it is gold? What do y'all think?
The numbers on one of them is M112 4099A

It's kinda hard to tell just from the pic but offhand I'd say it's straight brass, you might take an awl and make a scratch on one to see what color is under the surface.
Thanks Mechanic, I scratched it and it looks like copper underneath. I will go outside tomorrow, if we get sunlight, and see if that will give me a better view.
Scrapdollar, those are mostly all transistors. An Integrated Circuit or IC chip is essentially a lot of that stuff on those boards squished into an IC chip.
Dherik, I appreciated that! You just made a light bulb go on in my head:)

It don't matter to the refiners, gold is gold, they don't care where it came from.Quote:

Pizzaman, Are you talking about the alien War of the Worlds looking transistors? The one to the left has silver colored legs and the to the right has gold colored legs....... I will save them for my future cash account:)

If you need to identify stuff on a board check this site.

I'm glad someone else asked about these, as I have been saving the transistors and eproms as well. I had heard that they were going for $4+ a pound, but then couldn't find anymore info on it. I don't have many, but it's a start. Also, the ones that are soldered on, I also take a small flat head screwdriver and push it under one end of the transistor and pry upwards, they usually peel right off. Thanks for the info guys.
When I was a kid I used to like to fool around making circuits using the components I salvaged off broken electronics. Getting the components of with a soldering iron took too long so I tried out different alternative methods. I found that a twist knot wire wheel brush attached to an electric motor could be used to depopulate a board very quickly. It grids of the solder without damaging the components. Now that I've been reading about this stuff I realize that I probably shouldn't have done that without taking some precautions against the dust I was producing.Quote:
