Abstract

A carriage or dielectric disk (40) has a series of electrical contacts (46, 48) defined by conventional circuit board techniques on upper and lower surfaces around a peripheral edge. Sockets (42, 44) are wave soldered in electrical connection with the electrical contacts. At least the electrical contacts are plated with a hard, dense metal, such as nickel. When components have been frictionally inserted into the sockets, the carriage is placed in a cooling chamber (18). Air of a selected temperature is blown through a central port (22) and directed to flow over the surface of the carriage and the supported components (10). A motor (60) rotates the carriage to move the electrical contacts (46, 48) successively into electrical communication with relatively soft electrical contact springs (58) connected with a test instrument (32). The test circuit measures electrical characteristics or properties of each component at each of a plurality of preselected temperatures. Based on the measured properties, the components are sorted.
