Abstract: A test head assembly for a semiconductor device has a carrier, a pin seat and a test wire assembly. The carrier is formed in an L shape and has a lateral board, a perpendicular board and a opening formed through the perpendicular board. The pin seat is mounted in the corresponding opening. The test wire assembly has a teat head, a plurality of connectors and a plurality of test wires. The test head is mounted on an outer sidewall of the lateral board and connected to the pin seat through the test wires and the connectors. Therefore, the pin seat is mounted on the perpendicular board of the L-shaped uprightly and the test head is mounted on the lateral board. The pin seat and the test head are not parallel to each other, and a lateral size of the test head assembly is reduced to increase the space usage.

Abstract: A head of a tag device having a body, at least one row of negative-pressure through holes and at least one row of positive-pressure through holes. The body has a first surface and a second surface. The rows of negative and positive-pressure through holes are formed through the first and second surfaces of the body and arranged along a long-axis direction. Two negative and positive-pressure through holes at both ends of the corresponding row of negative and positive-pressure through holes are respectively close to the short sides of the body. Therefore, an effective labeling area is distributed between two short sides. The head of the tag device of the present invention provides a stable labeling operation for different products where different components are mounted and increases units per hour (UPH).
