Sintering in electronics assembly, is a bonding technique where high melting temperature metals such as silver or copper are used to form highly reliable interconnects with superior thermal and electrical conductivity. Sintering is a process of steady-state interdiffusion, the metal particles fuse together and fuse with the surfaces being bonded once sufficient heat is applied. Sintering can be performed pressure-less or with applied pressure. Indium Corporation offers both silver and copper sinter pastes for both pressure and pressureless processes.
A little over a year ago, I posted about the increase in interest regarding Cu sintering. In the past 12 months, that interest has surged, highlighting Cu sintering’s suitability for various
