Before cleaning/coating we wear gloves more to protect the operator from
chemicals or things on the "dirty" board. Don't you just hate it when you
pick up a flux-sticky board? From a contamination stand-point, if the assy
will be cleaned in the near future, handling with bare hands is little risk.
But I've seen some pretty fast corrosion from salty, acidy fingerprints. We
also wear gloves or finger cots during assy to protect moisture sensitive
components from contamination. If there are no MS devices we usually just
handle by the edges without gloves, as you probably do. After cleaning we
wear gloves to protect (maintain) cleanliness or again, handle by the edges.
Wearing gloves can be a real inconvenience (and risky) if not necessary, but
it sure looks good when the customer tours come through.

Yep,
good considerations on the gloves, thank you.
But what about my original dilemma, wear gloves on assemblies that will be
washed or not? Or, why wearing gloves when you cook, since you are boiling
the ingredients anyways?
And yeah, hockey is good, but football (real football, that you guys call
soccer) is better. Sorry, but I had to mention it, since I started the whole
thing...
Thanks again,
Ioan
