Flip-Chip Flux
The flip-chip process involves taking the singulated die from a wafer mounted on a wafer dicing tape, inverting ("flipping") them and placing them onto a substrate. The substrate may be a printed circuit board, a ceramic substrate, or (in the case of 2.5D and 3D assembly) an interposer.

Reflow of Copper Pillar Microbumps
Waferbumping processes have evolved in the last 10 years. The semiconductor assembly industry has gone from bumping processes using solder paste printing (with all its concerns of voiding, coplanarity, stencil-life, and spatter) to plated solderbumps, and now to plated copper pillars with microbumps…
NanoBond® is a Fluxless Process
Fluxes are an interesting element of working with many solder applications. With so many specialized fluxes there is usually a perfectly-tailored flux for removing oxides from any solderable surface. Even though we love fluxes at Indium Corporation – not all of our customers share that same affection. It…
The Magic of Engineered Solders
Engineered solders are solders that can make a HUGE difference with your thermal management, IGBT, die-attach, medical device, hermetic sealing, or connector assembly application. The possibilities are endless. One of my personal favorite engineered solders is Solder Fortification® Preforms.…
