Subject: Re: [TN] IPC Documents Dealing with Component Cleanliness?
Rich,
Must be a bad day (more snow is coming to our Hoosier homes tonight) because I am working late.
Anyway, I remember a poster paper Bev Christian gave at an Expo (2005 or 2006?) on this very subject of component cleanliness. So I have copied Bev in, or maybe some of the other regulars on TechNet remember the poster (I think that would have put the document in the IPC technical proceedings, but I don't have that at hand here right now.). Maybe it was 2005, as that was the Expo year we had all the foreign papers as part of the World Electronics Circuits Council event, and some other good papers got pushed out.
Of course, I don't remember full details, but seems to me Bev and RIM found a lot of variablity in component cleanliness, right after they had beaten up the board fabricators to ship clean boards. Sorry, I can't remember if they quoted a standard, or were making up one for their own incoming inspection/qualification.
Bev or others, help out.

I know that documents and standards exist for assemblies & PCB's, but
are any of you aware of any IPC (or other industry) documents that deal
with the cleanliness (both residual and/or particulate) of components or
mechanical parts such as housings, heat sinks, etc?
Rumor has it that there are some purchasing trade groups that may also
address this topic.
