Abstract

Abstract A method and apparatus for arranging and measuring and/or testing characteristics of subminiature semiconductors. The semiconductors are fed onto and lined up, one behind the other, on tracks which extend parallel with respect to each other. Electrode leads extending from the semiconductors are disposed between the tracks, thus provided. At predetermined locations along the tracks electrical contact means are provided which electrically connect the semiconductor electrode leads to measuring and/or testing instruments.
