Contact Sipad Systems and see if your board is a match for their process. They use a flux that stays tacky for weeks. We have used them in the past for exactly this reason and everything worked out well.

yngwie, are you getting a wave from the customer to say it's not your fault you fried the parts? Profiling's one of those things that is a pain to dobut it's one of the most important factors in the assembly processes. I've read and seen instances w

We have a system where when we set up the line to run a job before the first part is placed an auditor verifies we have all the correct parts loaded on the machines in thier correct locations. We then run a first article. The board is inspected to in

What methods do you guys use for maintaining lot and/or board traceability? When I worked in med. products, we used travelers that we recorded everything on, then serialized them at the end of the build. Not as effective as up front serialization,

The best method of cleaning misprinted boards is with a stencil cleaner. I would not recommend the use of a spray-in-air system for misprints. Spray systems can cause solder paste to become embedded into vias and under components (if double sided).

Yes!!! How can we assemble boards with 20 pitch when we allow 0.008� error to the master art? Excellent question!!! IPC-D-300G has nothing to do with assembler requirements. It is written by and for fabricators, so that they can be comfortable.
