SUBSTRATE WITH AT LEAST TWO METALLIZED POLYMER BUMPS FOR SOLDERED CONNECTION TO WIRING

摘要

A substrate (S) with at least two metallized polymer bumps (PS), especially a polymer stud grid array, is configured in such a way that the polymer bumps (PS) have at least one step (ST) and at least one elevation (E). The geometry of the solder bumps (PS) ensures that the soldered connections to the wiring (V) are secure and guarantees reproducible layer thickness for the solder (L).
