Abstract
Abstract Electrical components are provided with a pressure-sensitive adhesive fixed within an enclosure for the component. Any loose particles of material dislodged from the component and/or dust are trapped by the adhesive. The method of preventing inoperation of the component, resulting from contaminating particles, comprises disposing the pressure-sensitive adhesive within an enclosure for the component and vibrating the component to dislodge any particles loosely adhered thereto so as to trap the loose particles on the adhesive.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
64 words
A method of preventing inoperation of a component as described in claim 1, wherein said component comprises cover means defining an enclosure for said parts; said pressure-sensitive adhesive is disposed within said enclosure; and, the step of shaking said component comprises vibrating said component at a random frequency to dislodge loosely adhered particles within said enclosure and to trap said particles on said adhesive.
Claim 2
Dependent Claim
84 words
A method of preventing inoperation of a component as described in claim 1, wherein said component has a cover forming an enclosure for said component, said pressure-sensitive adhesive is disposed on at least a portion of the inner surface of said cover, and said shaking said component comprises vibrating said component at a frequency of between 10 and 100 Hz with an acceleration of between 2 and 10g until no noise, characteristic of said particles moving within said enclosure, is heard during said vibrating.
Claim 3
Dependent Claim
58 words
A method of preventing inoperation of a component as described in claim 1, wherein said component has a cover forming an enclosure for said component, said pressure-sensitive adhesive is disposed within said enclosure, and the step of shaking said component is continued until no noise, characteristic of said particles moving within said enclosure, is heard within said enclosure.
