DuPont Electronics and Imaging’s award-winning Solderon™ BP electroplating chemistries are reliable alternatives to tin-lead alloys for all wafer bumping applications, from standard C4 solder bumps to capping fine-pitch Cu µpillars.
Our lead-free, single-step plating materials are specifically designed for the most challenging advanced wafer-level packaging applications. A variety of formulations including tin-silver alloys, pure tin, and indium materials meet a range of process temperatures and melting points, suiting both high- and low-temperature processing needs. Designed to overcome our customers’ most difficult challenges, such as voiding and throughput, Solderon™ products feature:
DuPont Electronics & Imaging leads the way with low-alpha materials by offering tin with low-alpha-particle-emitting versions of our products, which are ideal for packaging applications sensitive to the effects of these emissions.
Solder bumps form the electronic interconnect between a chip and its substrate. In wafer level packaging processes, bumps range in size and shape from standard C4 bumps, to solder caps on Cu pillars and µpillars.
