ABSTRACT:
A process for manufacturing optocouplers having an emitter element properly oriented with respect to a receiver element. An emitter element is fastened to an emitter carrier. A receiver element is fastened to a receiver carrier. The emitter and receiver carriers are positioned adjacent one another to bring the emitter and receiver elements into operative relation. The combined operation of the emitter and receiver elements is electrically monitored while the position of the carriers with respect to one another is adjusted. On the basis of the electrical monitoring, a determination is made as to when a proper orientation between the emitter and receiver elements has been achieved. The emitter and receiver carriers may then be permanently bonded together for subsequent final packaging. The process described is particularly well suited to automated manufacturing.
