I would like to know if there are any IPC standards or anything remotely referring to having a Solder Paste Deposition tester in house to check the printing process. I have an interesting situation. Any help would be appreciated.

What kind of "auditor" is this? Who does this auditor work for HP or CR Technologies? Maybe the auditor can quote 'chapter & verse' of the IPC specifications that state: * Inspection of any type is required to assure solder print processing repeata

I have no opinion on the accuracy and repeatability tolerances you should be looking for on the vision system and the actual alignment of the stencil. I expect Cp=2 from my printer.

Entek is Enthone's OSP [organic solderability protection]. It is widely used in the PCB fabrication business. Imidazole (Via Systems) is good, but is not as widely available. Search the fine SMTnet Archive on: * OSP * Entek CU-56, Entek Plus CU-10
