    Hello Group,

    I am interested if there is an industry standard on the simple cleaning
    of a dirty IC of general grime (dirt, skin oils, grease, etc). I am
    thinking acetone or isopropyl alcohol should be ok. I searched
    SemiconFarEast.com for articles but came up empty. Is there an
    industry standard for general cleaning of a chip? Any help would be
    appreciated.

    soapy water works.

    ** Never use soap or washing powder - they are alkaline ( caustic) and
    will corrode metal..

    Ordinary dishwashing liquid ( ie detergent) is fine - the rinse with warm
    water and hot air dry.

    ( Beware: Dishwasher liquid is also caustic. )

    you had got it right buddy..........

    "isopropyl" is the best solution.But remember one good technique that i
    learnt about it...
    isopropyl evaporates quickly when poured directly on the board...

    instead what u do is take a very small piece of cloth or cotton bud(ear
    bud); dip in isopropyl and then clean it.... dont forget to close the
    bottle cap.... also i generally prefer to take small amount of
    isopropyl in a seperate small bottle so that u can dip the same old bud
    again and also prevent wastage....

    also it helps avoid accidents like dropping the bottle and damaging
    other things...

    Caution: Use gloves and face mask to be on a safer side...(its not
    that harmfull,but u must take precautions)

    Also if while using it u feel burning sensation in ur nose or eyes,
    stop its use immediately.
    I have learnt that some people are allergic to it but it is never
    noticed....(actully its Vapor causes it)

    You *must* ??? !!!

    I've never needed to do that with isopropyl used in small quantities.

    Apparently KruSat has never heard of an "alcohol rub." ;-)

    Cheers!
