ABSTRACT:
An oriented array of small, fragile electrical devices such as beam lead transistors or integrated circuits, partially embedded in wax, are removed from the wax and transferred to a releasable mounting without disrupting the orientation of the devices. The releasable mounting comprises a plate with a layer of silicone rubber or resin which exerts a suction or vacuum holding force on the array of oriented devices.
