Abstract (en)
[origin: EP0061550A2] A tri-metal contact film (31, 33) of silver, platinum, and palladium is metallurgically bonded to the opposite surfaces of a disk (11) of dense, controlled temperature coefficient of resistance thermistor material. The disk is trimmed to the desired electrical dimensions and a silver-clad wire (61, 63) is fusion welded by thermal compression bonding to the contact film (31, 33) on each side of the disk. The method of making electrical contact allows the assembly to be encased in a conformal glass coating (75). The glass coating (75) provides an enchanced stability thermistor having predetermined characteristics.
