IC Chip Consensus

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.

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.

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.

5 cent hit compared to what? i cerntinaly not going to pay $1 per pound to ship something thats less then a buck in return. SO yeah after i break all th elow grade boards to pieces and pull out the good stuff I sell the trash cans full of boards at 5 cents a pound.

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.

I assume you guys are talking about chips from brown boards? Like what is in a TV, or a monitor?

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.

I believe it means integrated circuit....

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.
