Abstract
Abstract A heat sink assembly to dissipate heat from electrical components to a housing is made in which the housing is formed from a suitable heat sinking material including a body with integral continuous walls extending from the perimeter of the body. A carrier mechanism which retains a plurality of electrical components is positioned within the housing. The electrical components have heat sink tabs which are positioned in the housing such that the tabs are coupled with the housing to dissipate heat from the electrical components to the housing. A resilient biasing member including a plurality of resilient fingers is coupled with the carrier mechanism to retain the carrier and electrical components in position on the housing.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
142 words
A method of manufacturing a heat sink assembly comprising the steps of: providing a housing formed from a suitable heat sinking material, a carrier means, at least one electrical component having a heat sink tab, and a resilient biasing means having at least one finger; placing said housing onto an automated assembly line; adding additional desired electrical components such as circuit boards by an automated process to said housing; positioning said at least one electrical component onto said carrier means; positioning said carrier means with said at least one electrical component by an automated process into said housing; and associating said resilient biasing means with said carrier means by an automated process such that said heat sink tab of said at least one electrical component is contacting said housing for dissipating heat from said at least one electrical component to said housing.
Claim 2
Independent Claim
142 words
A method of manufacturing a heat sink assembly comprising the steps of: providing a housing formed from a suitable heat sinking material, a carrier means, at least one electrical component having a heat sink tab, and a resilient biasing means having at least one finger; placing said housing onto an automated assembly line; adding additional desired electrical components such as circuit boards by an automated process to said housing; positioning said at least one electrical component onto said carrier means; positioning said carrier means with said at least one electrical component by an automated process into said housing; and associating said resilient biasing means with said carrier means by an automated process such that said heat sink tab of said at least one electrical component is contacting said housing for dissipating heat from said at least one electrical component to said housing.
Claim 3
Dependent Claim
35 words
The method according to claim 1 further comprising the step of fastening said biasing means with said housing to forcibly position said heat sink tabs of said at least one electrical component against said housing.
Claim 4
Dependent Claim
30 words
The method according to claim 2 further comprising the step of positioning multiple types of electrical components on said carrier to be maintained by said carrier means on said housing.
