I am surprised the godfather of cleaning has not responded on this. I remember a young Brian promoting cleaning standards for components in his hand book on cleaning and that was before the hard back book came out on the streets from Electrochemical Publications. I obviously was a young boy in those days learning about cleaning from my betters.

Regards Mike -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Bev Christian Sent: Thursday, October 09, 2008 5:03 PM To: [log in to unmask] Subject: [TN] Standards for Component Cleanliness Technetters, I know that the IPC has no standards for virgin component cleanliness. I have had our information specialist look for JEDEC ones and he couldn't find any there either. Did he miss something? Does anyone know if there are any IEC, ISO or Japanese standards that deal with this subject? Thanks.
