Abstract

In the fabrication of semiconductor devices 10 of the type containing three ball-type terminals 11 protruding from one surface, it is often desirable to move those devices from station A along a ledge or track 12 of a syntron bowl (see also A') and to present the devices with those terminals oriented in the particular manner represented at work station D. Devices being advanced from right to left along the track 12 may sometime be misoriented as represented at B and C.

Orientation of Semiconductor Devices With Ball Type Terminals

In the fabrication of semiconductor devices 10 of the type containing three ball-type terminals 11 protruding from one surface, it is often desirable to move those devices from station A along a ledge or track 12 of a syntron bowl (see also A') and to present the devices with those terminals oriented in the particular manner represented at work station D. Devices being advanced from right to left along the track 12 may sometime be misoriented as represented at B and C.

To assure that misoriented devices do not arrive at station D, their corner portions 13 and 14 which depend considerably below track 12 are engaged as they move along the track. Such engagement is by V-shaped projection 15 (see also plan view F) which pushes the device off the track back into the bowl. The latter then returns the displaced devices to the track for subsequent movement to work station D.
