Abstract

1368960 Soldering JOSEPH LUCAS (INDUSTRIES) Ltd 7 Oct 1971 [13 Oct 1970] 48498/70 Heading B3R In soldering, with a solder containing lead and tin, an electrical component to a fired paste thick film circuit, a surface layer formed from a glass frit in admixture with either platinum or palladium is applied to a terminal region of the circuit and subsequently the component is soldered to the surface layer with the solder. The substrate carrying the thick film circuit may be high alumina ceramic or glass and the terminal region may consist of fired paste containing palladium/gold/glass frit or palladium/ silver/glass frit to which an overlayer of fired platinum and glass frit paste is applied. Instead of the platinum and glass frit overlayer palladium and glass frit may be used. The solders employed may be 60% tin-40% lead or 62% tin-36% lead-2% silver.
