Germanium Dioxide (GeO2)
Germanium dioxide (GeO2) is a white powder that is manufactured in both crystalline and amorphous forms. Germanium dioxide’s refractive index (1.7) and its optical dispersion properties make it a useful material for wide-angle lenses and optical microscope lenses. GeO2 is transparent to infrared light.
Germanium dioxide is also used as a catalyst in the manufacturing of polyethylene terephthalate (PET) resins, and for the production of other germanium compounds, phosphors, and semiconductor materials.

Part 3 of the semiconductor flux series talks about the important cleaning function of fluxes and how thermocompression bonding can help prevent warpage and die tilt.
When looking at the reliability of AuSn solder paste, you need to take a couple of things into consideration, the post reflow alloy composition (off-eutectic) and the correct flux for the application are two of these.
Today's electronics continue to get smaller and smaller, so the traditional type 3 (-200/+325) mesh size might be too large for new scale-ups. This blog post reviews Indium Corporation's capabilities for making smaller AuSn particle sizes.
