- Drop-in replacement for high-Pb solder paste
- Pb-free and Sb-free
- Solidus > 260°C after reflow
- MSL1 proven per IPC/JEDEC J-STD-020D
Indium Corporation has developed a solder paste technology for high Pb-containing applications. This technology, called BiAgX®, creates a solder joint that re-melts at over 260°C.
- Drop-in replacement for high Pb-containing solder pastes, requiring minimal process optimization and no new capital expenditure
- Both Pb-free and Sb-free, conforming to applicable standards
- Available in both dispense and printing forms, like standard die-attach solder paste
- Reflows, solders, and solidifies like other solder paste
- Fluxes are cleanable with standard cleaning chemistry and processes
- Requires minimal adjustments when converting from a standard high-Pb solder paste-based process
- Suited to smaller die and lower voltage applications, such as those used in QFN packages for portable electronics, automotive, and industrial applications
- Contains no costly specialty materials, such as nanoparticles or gold
- Requires no pressure on the die during the reflow process
- Designed to work in high-temperature environments at temperatures in excess of 150°C with no degradation of the mechanical structure or other properties
- Evolving into a family of products, all based around a platform technology
Indium Corporation also offers other die-attach solder materials, and is currently the only materials supplier in the Automotive Electronics Council (AEC).
- Solder Pastes - dispense and print
- Solder Preforms
- Solder Ribbon and Foil
- Die-Attach Wire

I'm just back from Malaysia, where I visited one of our larger customers who has been using our high-lead (high-Pb) dispensable NC-SMQ75 solder paste for many years. No surprises there, but what many people don't realize is that the NC-SMQ75 solder paste can be used as a no-clean material...
Folks, An obvious disadvantage of lead-free electronics soldering assembly is that the oven must be hotter and therefore will use more electricity (versus 63Sn37Pb soldering). But is the extra amount of electricity significant? Bill O'Leary claims...
