Open circuit and intermittent defects are the worst problem an engineer can face in manufacture, difficult to find and often a problem to get to the root cause. The increasing use of area array packages and package on package assembly combined with lead-free processes has highlighted a new defect type referred to as head in, or head on pillow. We explain the problem, process parameters and ways of eliminating this type of defect during assembly

This type of failure is not unique to lead-free or area array components we have been experiencing a similar problem in the past with fine pitch packages which will also be illustrated during Bob’s webinar

Topics Covered:

What is Hip and Hop
Same defect type on surface mount
Solder sphere oxide

Reducing void formation in reflow
