A force distributor is configured for disposition between a printed circuit board and a stiffening plate, which is spaced from the printed circuit board. The force distributor is configured to distribute a compressive force between the printed circuit board, an interposer and a land grid array module carried on a side of the printed circuit board opposite the stiffening plate. The force distributor comprises a spring element comprising a first portion and a second portion with the first portion extending radially outward from the second portion. The spring element is configured for placement so that the first portion is secured to the stiffening plate and the second portion is biased in unsecured, pressing contact against the printed circuit board.

The present invention relates to a method and apparatus that prevents/minimizes cracking in the ceramic body of processors. The ability to prevent/minimize cracking can ensure successful operation and substantially increase processor lifetime. The present invention discloses a device for maintaining a microprocessor in a desired relationship with a printed wiring board while limiting the transmission of shock and vibrational motion to and from the processor includes a printed wiring board, a processor, and a dynamic isolating mount compressed between the printed wiring board and the processor, wherein the processor maintains the dynamic isolating mount in a compressed state such that the dynamic isolating mount bears on the printed wiring board.

Dynamic isolating mount for processor packages

A self-locking interposer restraint mechanism is disclosed. Rather than using screws to compress springs, clips are pushed down over the posts to compress the springs. Once the clips are pushed down to a level at which the springs are sufficiently compressed, the clips engage stops fabricated into the posts thereby locking the restraint mechanism.
