Assignee:

Micron Technology, Inc. - Boise ID

International Classification:

B29C 4502
B29C 4514
B29C 3330

US Classification:

425116

Abstract:

Transfer molding equipment, used to encapsulate semiconductor die, is provided with clamps mounted to the mold base to position and align mold chases. Previous designs position and align the top and bottom mold chases using dowels on the mold base received in holes in the chases. The invention reduces the downtime of the mold equipment, and decreases the time required to replace the chases when a different package is to be produced.

Filed:

Feb 7, 1996

Appl. No.:

8/598148

Inventors:

Morley J. Weyerman - Boise ID

Assignee:

Micron Technology, Inc. - Boise ID

International Classification:

H05K 330

US Classification:

29827

Abstract:

A method is provided that increases the efficiency of material handling apparatus, such as those used to trim and form electrical leads on solid state electrical devices. The method uses a plurality of rotatable pulleys, an endless belt capable of retaining devices to be processed that is disposed around the pulleys such that rotation of the pulleys will cause said belt to travel around said pulleys, and a plurality of paired tooling members, each of said paired tooling members having first and second tooling members disposed on opposing sides of the belt and directly opposing so as to cooperate and perform a tooling operation on the leads when reciprocated toward each other along a common axis. In a preferred embodiment, two horizontally aligned pulleys with vertical axes of rotation are used to rotate the belt in a horizontal plane. The electrical devices are contained in a lead frame which is retained by pins on the belt which pass through indexing holes in the lead frame and the faces of the electrical devices are vertically oriented.

Abstract:

An apparatus is provided that increases the efficiency of material handling apparatus, such as those used to trim and form electrical leads on solid state electrical devices. The apparatus includes a plurality of rotatable pulleys, an endless belt capable of retaining devices to be processed that is disposed around the pulleys such that rotation of the pulleys will cause said belt to travel around said pulleys, and a plurality of paired tooling members, each of said paired tooling members having first and second tooling members disposed on opposing sides of the belt and directly opposing so as to cooperate and perform a tooling operation on the leads when reciprocated toward each other along a common axis. In a preferred embodiment, two horizontally oriented pulleys are used to rotate the belt and the first and second tooling member are reciprocated by a common cam and the rotation of the belt and the reciprocation of the tooling members are synchronized. Alternatively, the first and second members can be driven by different cam drives that are synchronized.
