Abstract
Abstract Apparatus is provided for mounting an electronic component having a pressure sensitive active area, which apparatus permits the component to expand and contract with changes in temperature and which does not introduce stresses into the active area of the component. The apparatus includes a cradle which, when attached to a substrate, forms a partial enclosure of the component but which leaves the active area unobscured. A packaging system is also provided wherein the bottom of the cavity of the lower portion of a standard integrated circuit package forms the substrate to be used in conjunction with the cradle for containing the electronic component.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
88 words
An electronic apparatus comprising: a base having a cavity therein; an electronic component in the shape of a rectangular parallelepiped in contact with the bottom of said cavity, said component having a pressure sensitive active area; and cradle means attached to said bottom for constraining translational motion of said component, said cradle means forming a partial enclosure of said component without contacting said component while leaving said active area unobscured, said cradle means comprising two L-shaped pieces, each configured to fit on one corner of said ractangular parallelepiped.
Claim 2
Dependent Claim
