Renu, We examined boards under magnification upon setting up the cleaning process. We utilize an automatic cleaner - as we do for stencil cleaning. We do not permit hand cleaning of misprints. Smartsonics, or ultrasonics are utilized with Armakleen E-2001SC. Visual inspection is performed after cleaning. Hope this answers your questions.

What do you look for? Are any remaining solderballs unacceptable? Is there an IPC spec or any other type of spec that details what to look for in such boards? Any comments, suggestions would be greatly appreciated.
