Abstract
The present invention provides an electronic component part with terminal pins very closely and very strongly bonded to a high thermal conductivity ceramics circuit board and a method for simply and continuously manufacturing electronic component parts, with a high operability, each with terminal pins bonded to a high thermal conductivity ceramics circuit board. According to the present invention, an electronic component part is provided in which terminal pins are bonded to a high thermal conductivity ceramics circuit board by a brazing metal, containing at least one kind of Group IVa elements. In another aspect of the present invention a method is provided for manufacturing electronic component parts, which comprises the step of attaching terminal pins to a high thermal conductivity ceramics circuit board by a brazing paste layer comprised of brazing metal powder containing at least one kind of Group IVa elements, an acrylic binder with a carboxylic group as a substituent group and organic solvent, and heating the resultant structure in an atmosphere containing nitrogen as a principal element so that terminal pins are firmly bonded to a circuit board.
