The trend of increasing complication in the rework arena continues. Sources of today’s rework challenges include the development of smaller and smaller components and the continued difficulty of reworking BGAs (with defective, deformed, or missing balls). Add to that, the necessity for contract manufacturers to have a reliable solution to reduce waste continues.

The need exists to blend ‘typical’ rework (SMD components, lead-free solder and 0201) with more complex rework, such as single ball reballing. Or, simply put, to reuse BGA components that have failed capillarity tests or have arrived from the manufacturer as defective parts.
