Abstract
Printer wire assemblies for dot matrix printers are characterized by a copper layer on the tungsten wire extending beyond the base portion inside the pin socket, to protect the wire from the embrittling effects of brazing, by braze-forming layers on the copper layer and by a blind-hole pin socket, to enable ease of assembly and braze-bonds of uniformly adequate mechanical strength.
