TechNet, I am working on a quality team to improve our surface mount assembly processes and was critiquing some SMD boards from other manufacturers and was wondering why some of them are putting a clear over-coating on fine pitch (.025" and smaller) parts after they are attached to the board. It seems to me that this would limit re-work (if required) unless there is some way to remove the coating. It would also mean that no probing of the parts could be done in a troubleshoot area. There must be some good reasons for this clear coating applied to the leads. Please let me know of any reasons all of you have!
