Title: Contacting carbon layer resistors on conductive track - uses copper layer coated with palladium, nickel and gold to prevent oxidation during heat treatment
Inventor: HOHMANN ROLF
IPC: H01C17/28
Filed: 1974-03-18
Abstract: The carbon layer resistor, hardened by heat treatment, is produced on conductive strip which may oxides at the treatment temperature. To prevent this oxidation, the copper strips, formed by an etching process on the substrate have a thin layer of palladium deposited on the copper strips. A nickel layer is then deposited onto the palladium to a thickness that prevents diffusion between the final gold layer and the copper. This thickness is achieved by depositing the nickle in two stages. The gold layer is then deposited on top of the nickle. The carbon paste is then placed between the strips and the assembly heated to 180 deg.C. The layers of metal over the copper prevent the latter from oxidising during the heat treatment for hardening the carbon paste.
