    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.

    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?

    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.

    That's silly. But hey, every yard is different.

    Being a noob still. can someone explain or better yet, put up a pic of these IC chips?

    What does IC stand for?

    The removable chips I take off we refer to as E-Proms...

    Thanks.

    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.
