hi, the good old days weren't all that bad. when i needed to have a specification callout for a conformal coating on an engineering, i just used mil-i-46058, type ur (for example), and the drawing checkers were quite happy. since mil-i-46058 has been cancelled with no replacement, what to do? i couldn't find an ipc equivalent to mil-i-46058 (that is one that has a 'qpl' associated with it. what do i put on my drawing notes and parts list? do conformal coating vendors qualify to ipc-cc-830b? thanks, phil -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Gerry Savard Sent: Monday, June 27, 2005 6:30 PM To: [log in to unmask] Subject: Re: [TN] No-clean residue requirements IPC-A-610D, section 10.4.1, states as acceptable, Class 1,2,3 "No discernible residue from cleanable fluxes is allowed" and "Flux residues from no-clean processes may be allowed." The 'may be allowed' part I believe covers the bases for those products that have to be super clean depending on its end-usage. In general, no-clean will leave some residue which is acceptable since it's activity is very low.

Perhaps I'm missing it, but there doesn't seem to be any clear statement about no-clean residue vs water wash in the standards. Any help out there? Thanks in advance.
