Abstract

A perforated heatsink as shown in the figure has a plurality of access holes therein. The primary purpose of the access holes is to permit access to test points on the card to which the heatsink is mounted and to reduce the cost of card test points due to an overhang of the heatsink.

Perforated Heatsink

A perforated heatsink as shown in the figure has a plurality of access holes therein. The primary purpose of the access holes is to permit access to test points on the card to which the heatsink is mounted and to reduce the cost of card test points due to an overhang of the heatsink.

Additionally, card test points can remain close to the perimeter of the module. This is important to prevent unduly long stubs that would result from test points being located beyond the perimeter of the heat sink.

The addition of the holes will provide for more surface area and thus, a more efficient heatsink for the area the heatsink covers on the card.
