Richard,
To my knowledge, IPC has no documents addressing the issues of required 
cleanliness of components.  I did some research a few years ago and IPC 
specs only deal with cleanliness of boards and assemblies.  There have 
been no specification efforts related to components from the Cleaning and 
Cleanliness committees, which I chair.  The most that you see is "warm and 
fuzzy" statements like the components should be clean and free of harmful 
substances, but nothing with more teeth than that.

I do not know if there are any IEC specifications which might.  You might 
check on the IEC web site, www.iec.ch.  Graham Naisbitt, a valued 
contributor here on the Net, has more experience with IEC specs and may be 
better able to answer that one.

Subject
[TN] IPC Documents Dealing with Cleanliness?






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.
