Perhaps I should have prefaced Question 1 with INCOMING!!!!!!

A commenter has indicated that we should have a section discussing 
possible contamination or process residues that come from "Processing 
Aids" in board fabrication operations.  We already discuss items like 
sharpees, grease pencils, tapes, stickers, etc.

What other "process aids" should be included in a primer on board 
cleanliness for fabricators and why?

One of the commenters for this was Dewey, and the IPC Dewey filter 
automatically routes those to a black hole.......
