Copper Pillar Electroplating: Important Shape Limits

Summary for copper pillar electroplating Discussion

Copper pillar electroplating is the focus of this question, with Kevin Lee asking whether it is possible to plate copper pillars onto dome-shaped or pointy-shaped surfaces, and how to begin plating dome-shaped pillars. In the excerpt provided, no technical answer is shown, so there is no documented guidance on process setup, feasibility, or surface preparation. The thread only establishes the problem statement: Kevin has seen dome-shaped copper pillar plating in print, but has never seen a pointy-shaped version and wants to know if it can be done. Because the answer text is missing from the excerpt, no named responder advice can be summarized here. The page therefore reads as an unanswered or incomplete discussion in the supplied source, centered on whether copper pillar electroplating can conform to non-flat geometries.
