Indium Corporation announces a new solder paste technology. BiAgX® is a high-melting lead-free (Pb-free) solder paste technology designed for high reliability electronics assembly applications. Designed as a drop-in replacement for standard high Pb-containing solder pastes, it has passed MSL1 and thermal cycle testing at several power semiconductor customers.

BiAgX® is excellent for small, low-voltage QFN packages that are used in portable electronics (smartphone/tablet), automotive electronics, and industrial applications. It excels in high temperature environments in excess of 150°C. It requires minimal process adjustments and no capital expenditures for customers converting from a standard high Pb-containing solder paste-based process.

BiAgX® addresses both customer demands and potential legislative changes that eliminate lead from high-melting die-attach applications. It is both Pb-free and Sb-free (lead and antimony) and does not contain costly specialty materials, such as nanosilver or sintering aids.

BiAgX® reflows, solders, wets, and solidifies just like any other solder paste, and is available in both dispense and printing forms. Fluxes are cleanable with standard cleaning chemistries and processes.
