We believe your problem is caused by the mismatch in CTE of the material ised in your BGA. In fact, this "potato chipping" [where the corners curl-up] is present in all BGA. The issue is the matter of degree. [Mismatching CTE is how old thermostats

Has the pandemic and the economic fallout from it cause you and your company to rethink your China/Asia outsourcing strategy? Also have your thoughts changed regarding JIT/Kanban/Lean manufacturing practices in view of the present situation?
