International Classification:

H05K 7/00
H05K 7/20
H05K 1/14
H01L 23/34

US Classification:

361747, 257718, 361769, 361709, 361719, 361720, 361736, 361748

Abstract:

In a burn-in test configuration wherein a chip board having a plurality of semiconductor chips engages a heat sink board having a plurality of heat sinks. When the boards are operationally engaged, each semiconductor chip has a heat sink spring-loaded against the semiconductor chip. Posts coupled to one board engage posts located on the other board. The engagement of the posts orients and secures the relative positions of the two boards. A clip is provided that secures the relative position of the two boards when the two sets of posts are engaged. To uncouple the two boards, a pressure on the side of the clip permits the two boards to separate.

US Classification:

438106, 438 14, 438 15, 438 16, 438 17, 438 18, 438 51, 438 55, 438 64, 438107, 438612, 257E21499, 257E215, 257E21505, 257E21512

Abstract:

A semiconductor device with a semiconductor die thereon and a contactor board are electrically coupled when the electrically conductive elements on the semiconductor device and the contactor board are in physical contact. A continuous electrically conductive path is formed with electrically conductive elements involving both the semiconductor device and the contactor board. A complete electrical circuit involving both the semiconductor device and the contactor board is formed only when the relative orientation of the semiconductor device and the contactor board have predetermined relationship and the electrically conductive elements of the two boards are in good physical contact.

H01L 23/24

US Classification:

361747, 361769, 361748, 257718

Abstract:

A clip for coupling a first board and second board, the first board having plurality of first post coupled thereto, the second board having a plurality of second posts coupled thereto, each second post being a cylinder for receiving a first post, the first and second boards having a predetermined relative position when the second posts fully engage the first posts, each second post having an aperture in a side exposing the interior of the cylinder, each first post having a tapered end and a notch around the posts. The clip includes a base member, the base member being coupled to the second board, a top member, the top member having an aperture therein, and a side member connecting the top member and the base member, the side member fabricated so that an edge of the aperture is forced through the aperture into the interior of the second post, edge being forced into the notch when the first and the second posts are engaged and the first and second boards are in the predetermined relationship.
