Glass Microspheres
Solder spheres – a little larger than microspheres
I have not found a good answer in a search for the finite size range for solder microspheres. Glass microspheres have a defined size range of 100 nanometers to 5 millimeters in diameter. That’s too big of an upper range for solder.Forget 5mm – even .5mm is a large solder sphere.To set some size range, I think ≤200um diameter makes sense. Let me know what you think.
In my previous blog post on formic acid soldering, I explained the technology of formic acid reflow soldering, the applications in which it can be beneficial over traditional reflow soldering, the
Indium oxidation is not merely a surface phenomenon—it plays a critical role in the performance and reliability of high-precision applications, including semiconductors, AI, high-performance
At Indium Corporation, we understand the challenges related to power electronics assembly; devices are increasing in complexity, while demands on performance and reliability grow stronger. On top of
