Technology and design in electronic equipment| Summary: | Using modern diagnostic microanalysis tools, the regularities of changes in the electrophysical parameters of Ni‑B electroplated coatings of IC packages during ultrasonic welding of internal Al leads and package sealing have been established. An optimal electrolyte composition has been selected, providing increased heat resistance of IC packages with alloyed nickel coatings, which, in combination with local gold plating, enables the mounting of chips through a eutectic Si‑Au sublayer.
