Abstract
A compliant middle member to be used between encapsulated stacked circuit boards contained in an enclosure. The compliant middle member absorbing expansion forces from an encapsulant experiencing thermal expansion, thereby diverting and reducing the expansion forces exerted upon the electrical components.
Claims10
A stacked circuit board comprising:
- a housing;
- a compliant member;
- an encapsulant;
- and
- at least a first and second circuit boards stacked one on top of the other in the housing having the compliant member positioned therebetween;
- the at least first and second circuit boards and compliant member encased by the encapsulant;
- and
- whereby the compliant member compresses during thermal expansion of the encapsulant, thereby reducing expansion forces exerted on the first and second circuit boards.

A stacked circuit board comprising:
- a housing;
- a first circuit board with pins;
- a second circuit board stacked on top of the first circuit board and in electronic communication with the first circuit board via connection with the pins;
- a compliant member between the first and second circuit boards;
- the compliant member having holes through which pass the pins;
- and
- an encapsulant;
- wherein the first and second circuit boards and compliant member are contained within the housing and surrounded by the encapsulant;
- and
- whereby the compliant member compresses during thermal expansion of the encapsulant, thereby reducing expansion forces exerted on the first and second circuit boards and the pins.
