Mathematical modeling of soldering iron heating process in automated terminal soldering installations

Geometrical effects in a Joule heating problem from miniature soldering

The soldering of small, delicate electronic devices by means of a blade thermode (a small, thin, rectangular or -shaped soldering iron) requires the lower side of the thermode to have a uniform temperature distribution. This is not easily obtained: during start-up the corners tend to be too hot, and too cold in the stationary phase. In the present study the various aspects that determine the he...

Brazing & Soldering Today

JULY 2012 50 High-temperature solder alloys are extensively used in dieattach, power semiconductor, and optical device packaging, flip-chip packaging, etc. Current industry standard solders for these applications are mainly high-lead solders (90–97 wt-% Pb) and gold-based eutectic solder alloys such as the 80Au20Sn solder. The die-attach process involves connecting the silicon die or chips to a...
