Indium epoxy fluxes have stable thermoset residue

Indium Corp. has launched the PK-001 and PK-002 flip-chip epoxy fluxes designed for use with Sn62 and Sn 63 eutectic solders.

The PK-001 and PK-002 are fast curing, halide-free, no-clean fluxes which can be used for flip-chip or CSP soldering processes. Both environmental-friendly devices have a stable thermoset residue, and can be applied through pin transfer, stencil printing, dispensing or dipping techniques.
