Hello folks,

We have a problem with some IC's and solder quality on a board that we are running.  The inspector told me we had problems with the toe solder joints.  The reflow throughout the rest of the board looks pretty good.  This solder problem around the IC is not a consistent one. The solder is not rejectable, but we would like it to look better.

I have tested our profile with some profiling tools and the profile is very good.  Our paste is only 1 day old.  Could it be some of the pads on the raw board?

Is there anything else that you folks would check as part of a typical problem solving approach as I am relatively new to the industry.

Your comments would be greatly appreciated.


Thanks,

rob day
