More information please. Tell us about: * Board solderability protection * Your process and materials * Breadth and scope of the problem

So why are you telling us about the solder bar? What is the flux? that is what you need to change, you have a rosin based flux it sounds like. you can change probes in test fixtures or change flux chemistries. Russ

Any recommendation to reduce solder beads next to 0402, 0603 and 0805 caps and res? What about home plate vs. bow tie stencil aperture design?

How about a stepped stencil? Not ideal but ... As far as overprinting goes, try: http://www4.uic.com/wcms/WCMS2.nsf/index/Resources_44.html

Would say about the same as above, 8mm according to a cookson presentation we had, of course it would depend a bit on the paste you are using.

Chunks, your right, I need to get out more. What are you doing Saturday night? Harry is right about the software version compatability with trackballs. What is the version and machine type?

We have our circuit board vendor put a solder mask dot over the vias after HASL process. It's a little more expensive but eliminates the problem that you are talking about.
