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:

I am buying the IC Chips for 3.80-4.00/lb even with the current wacky market.

Not that I know of, there is a certain type of capacitor that has a little smidge of palladium in it but nothing in the transistors.

Right. got ya now :)

I call these flat packs. got that term from another forum. A sharpened cold chisel gets em off quick too!

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:)

sometimes the 3 legged transistors in the second pic have gold legs on them, I came across a few the other day in some vintage stereos.

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

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:)

Those are not IC chips. Accept the one in the middle. Those are Transistors.

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.

Best to leave the chips on the boards unless they are removable. Just my opinion.

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.
