Abstract

Commercially available solid-state devices, for example power transistors, have physical configurations which are diverse. There is no common physical feature in power transistors that will relate them to each other for handling purposes. Depicted in the drawing is a component carrier that will accept and handle many of the devices, exposing their leads for testing by the same test equipment.

Component Carrier for Use in Test Equipment

Commercially available solid-state devices, for example power transistors, have physical configurations which are diverse. There is no common physical feature in power transistors that will relate them to each other for handling purposes. Depicted in the drawing is a component carrier that will accept and handle many of the devices, exposing their leads for testing by the same test equipment.

The component carrier 1, as seen in Fig. 1, is a molded plastic assembly consisting of a body 2, plunger 3, spring 4 and plug 5. There are lead holes 2A in the body 2 to accommodate the various components. The plunger 3 also has lead holes 3A. The plunger lead holes 3A are intentionally shown misaligned from the body lead holes 2A in Fig. 1.

To insert a component, the plunger 3 is pressed down into the body 2. This aligns the lead holes of the plunger 3 with the lead holes of the body 2. The component leads are inserted into the holes and the plunger 3 is released. The released plunger is pushed up into the body by the spring 4 wedging the leads, which holds the component to the carrier 1. The leads are exposed in the open section 1A of the carrier 1. Referring to Figs. 2 and 3, the component is held to the carrier 1 by its leads, which are the objects that must be precisely aligned for contacting by the test equipment sliding test contacts.

Instead of trying to hold different components by their "bodies", which may vary greatly, t...
