    IC Chips

    Hi, I have been accumulating IC Chips for a while now, and am wondering what to do with them. I have set aside the ones that appear gold plated. I have a 5 gallon bucket of plain ones left over. I see that most e-waste buyers pay around $5-6/lb.



    My question is if there is a variance in values for the plain IC Chips like there is with CPUs( 6/lb-130/lb), and I should go through the bucket and research the labels and ser. numbers, or if they are mostly the same and I should just sell them.

    Thanks in advance,

    The gold ones are the ones that have more value ahead of the plain ones. I have never heard of any difference in the plain ones. Are you removing the stickers off the gray ones to check for gold window chips?

    The best thing you can do is determine what IC chips you have, I use a website octoparts.com and put in the numbers until I can ID the chips, then I search ebay for those chips. I sold a few hundred rare IC chips last year. I had not researched them, and just sold them to my normal buyers I would have lost at least $1,000.

    Yea, but after he's chiseled them off the boards the only value they have would be scrap value.

    After you get done sorting, cram as many as possible into a flat rate box or envelope and send to one of our buyers, Your profit will definitely outweigh the shipping.

    In addition to CPU removal, it could, in some circumstances, be worthwhile to carefully desolder the three other central IC chips on a typical PC motherboard.
    1) Northbridge
    2) Southbridge
    3) GPU (graphical processing unit)

    for more details (see):
    http://en.wikipedia.org/wiki/Northbr...28computing%29
    also
    http://en.wikipedia.org/wiki/Graphics_processing_unit

    As stated earlier, before expending the time and energy (and establishing thorough ventilation) that careful desoldering requires, I would check the chip details/serial #s.

    Certain Northbridge and Southbridge ICs have collectible value (certainly for older computers that some collectors attempt to reassemble).

    Some GPUs have resale value if removed carefully and stored in a static free environment. Some older GPUs also have collectible value.

    Here is an example of a collectible non-CPU motherboard IC chipset:

    The original IC chipset for the Commodore Amiga computer (chips were named: Agnus, Denise, and Paula)
    http://en.wikipedia.org/wiki/Original_Amiga_chipset

    Here is an example of someone attempting to sell 3 untested/functionality-unkown Agnus chips for $10. (I don't know if they'll sell, but it's interesting to see the attempt).
    http://www.ebay.com/itm/LOT-3-COMMOD...item20c2037b96

    Here is the Denise Chip selling for $30.

    Here is the Paula Chip selling for $3/chip ($30 for lot of 10)

    The NEAT chipset from early IBM PCs and clones is another relatively collectible set of IC chips.
    If you type almost any of these chip names into Ebay, you'll get plenty of sales for much more than scrap value.

    Funny, I was on YouTube this morning looking up that very thing while having my "wake up" coffee. There's lots of vids on that subject there. I've read some threads on this site where folks talk about using a wood chisel to take them off, but was afraid I'd break them into ten pieces before I got the hang of it. Just about all the vids on YouTube show folks desoldering or using some kind of a heat gun. I think I like the heat gun method the best. Less chance of breaking the chips (or gouging my fingers) and less mess.

    But I dunno, I'm still trying to learn myself.

    I use a 4 1/2" angle grinder with a thin metal cut off blade and run it along were the legs aare soldered on the back of the board. Ware a dust mask if your going to try this and I only do this on low grade boards.

    Desoldering a chip is very simple. You go to radio shack and get a desolder braid. Hold the braid on the pins with a soldering iron and it sucks up the solder. The chip can then just be lifted off the board. This is the ONLY was to remove a chip that you want to reuse. You can practice on capacitors once or twice till you get the hang of it. There are a bunch of vids on youtube that show the proper technique. If you are not going to reuse the chip/board I just use my torch to heat the back of the board and wiggle the chip.

    Removing attached chips from boards downgrades the boards so it might be wise to research the value of the board first, before you go to cutting, heating and burning. Check with your board buyer to find out what is acceptable to them.

    I am not a fan of removing chips but I understand why some do.
    I think the easyest way is to use a heat gun. Just heat up board and part untill it pulls off.

    I take my razor knife, and cut/scrape the solder from the backside. Then a flathead screwdriver easily wiggles out the chip. The fastest way, If only using them for scrap.

    Jghilino, that's why I only remove the chips from low grade boards. Every buyer that I've dealt with will buy low grades with or without the chips and pay the same price.
