Abstract
Abstract An electro-mechanical package is disclosed which includes an LCD and an IC chip mounted on opposite sides of a PC board by common package-retaining means, which includes posts extending through the PC board and a clip member that latches onto the ends of the posts to retain the package in assembled position. The latching action is resilient and permits non-destructive disassembly.

Claim 3
Dependent Claim
81 words
The electro-mechanical package of claim 1 wherein the visual display component comprises: a liquid crystal display member having electrical terminals thereon facing the PC board; an LCD holder having a body portion between the liquid crystal display member and the printed circuit board and having a recess therein to receive the liquid crystal display member; and means also supported by the LCD holder for electrically interconnecting the individual terminals on the display member with the circuitry on the printed circuit board.
Claim 4
Dependent Claim
62 words
The electro-mechanical package of claim 2 which also comprises: a cover member fitting over the LCD holder and having an opening through which the liquid crystal display is viewed; said cover member and LCD holder having interengaging latching surfaces, one of which is resiliently displaceable, whereby the cover member and LCD holder may be pushed together until they latch in assembled position.
Claim 5
Dependent Claim
42 words
The electro-mechanical package of claim 3 wherein the electrically interconnecting means comprises: an elastomeric strip providing alternate layers of conducting and non-conducting material extending perpendicularly to those surfaces of the liquid crystal display member and printed circuit board which face one another.
Claim 6
Dependent Claim
51 words
The electro-mechanical package of claim 4 wherein the cover member has a plurality of spaced spring fingers which resiliently press on the face of the liquid crystal display member to provide widely distributed, independently sprung pressures thereon, thereby exerting a compressive force on the perpendicularly extending layers of the elastomeric strip.
Claim 7
Dependent Claim
102 words
The electro-mechanical package of any one of claims 1 through 5 wherein the package-retaining means comprises: a plurality of perpendicularly extending posts mounted on one of the components and extending through holes in the printed circuit board and in the other component, the posts having a close fit in their respective holes to provide alignment of the components with the printed circuit board; and latching means including a retaining member and means on the ends of the posts for retaining the components in assembled position on the printed circuit board after the retaining member has been placed in engagement with the posts.
Claim 8
