ABSTRACT:
Reeled axial-lead devices such as diodes, resistors, capacitors, inductors, transistors and SCRs are carried in linear array by two coextensive tapes wound about a reel. The reel-to-reel apparatus of the invention includes a take-up reel and drive means for conveying the taped electrical components from the supply reel to the take up reel, and disposed intermediate said conveyor is an environmental chamber through which the taped reel is threaded. While in the environmental chamber, the electrical components and the tapes are selectively subjected to differential temperatures whereby only the electrical components are heated or cooled to the desired temperature preparatory to testing. Subsequentially, each electrical component is sequentially tested, and if found defective, is removed from the tape carrier by cutter means. The reeled components are then wound about the take-up reel.
