Solder preforms, e.g. solder balls used in micro-electronic applications for assembly of integrated circuits, have a uniform coating of a silane derivative for protection against oxidation

摘要

Solder preforms, particularly solder balls, are surface-coated with a uniform coating of a coupling agent comprising a silane derivative for protection against abrasion, and to limit the formation of an oxide layer. The coupling agent is a silane derivative of formula Si(R1)(R2)(R3)(R4). R1, R2, R3 and R4 = radicals. An Independent claim is also included for the method of production of the preforms.
