Title: Mold type flat package
Inventor: NAKAUCHI OSAMU
IPC: H05K1/18
Filed: 1988-06-10
Abstract: PURPOSE:To solder a lead before a package is overheated by applying a dark- colored coating, which is heat-resistant and does not allow adhesion of a solder thereto, on a surface of the package excepting a surface to be soldered to form a coating film on the package. CONSTITUTION:A flat package includes a resin-molded package 1 and a plurality of metal leads 2 protruding from the side of the package 1. In reflowing of a solder due to heating by infrared rays upon mounting the flat package, a silver-colored surface of a stock material is covered with a black-colored coating film 3 at a base part 2a and an intermediate part of the lead 2. Accordingly, reflection of the infrared rays on those parts is reduced, and instead the infrared rays are positively absorbed to ease heating of the package. Hereby, temperature of the lead is raised for a short period of time to solder the lead prior to the package being overheated.
