Thread: Cleaning sticker residue from EPROM chips (which solvent?)

  1. #1

    Question Cleaning sticker residue from EPROM chips (which solvent?)

    I just finished taking the stickers off of 22 AMD Am27C010 -120 EPROMs. Didn't get everything, and there is some adhesive residue left.

    What common products will remove the residue?

    I'd try 91% isopropyl...

    Seconded. Use a q tip and be careful to avoid any markings.

    My first try would be paint thinner (mineral spirits), then perchloroethylene. Since windowed EPROMs are cerDIP packages, you can't really hurt them.

    Goo Gone works for me (mostly stickers on laptops), made from petroleum distillates and citrus.

    I use these for everything:

    pre packaged alcohol pads. THICK, and absorbent. I get mine at my local pharmacy for slightly less. Honestly 70% alcohol works just fine.
    It is a mistake to think you can solve any major problems just with potatoes.

    Isopropyl alcohol, apply with whatever. The markings on CERDIP should be unaffected. I often just clean the window, that's really the only part where it matters, and the quartz is usually slick enough that any residue comes right off.

    Hi test alcohol? You mean this bottle of 151 Rum can be used externally?

    I've been known to buy everclear for use as a degreaser instead of for drinking.

    I just use (carefully) WD-40 and a qtip.
