Method for a stamped strap heatsink clip with outward facing feet and a stamped flat wire heatsink clip

Disclosed is a method for a stamped strap heatsink clip with outward facing feet and a stamped flat wire heatsink clip. Benefits include improved reliability and retention.

Description

        � � � � � The disclosed method is a stamped flat-strap heatsink clip (see Figure 1) and a stamped flat wire heatsink clip (see Figure 2). The clip feet of both heatsink clips are outward facing, which prevents undesirable clip pop out (see Figures 3 through 6). Because the clip is stamped, the cost is very low.

Advantages

        � � � � � Some implementations of the disclosed structure and method provide one or more of the following advantages:

•        � � � � Improved reliability due to outward facing feet that prevent the clip from popping out during dynamics

•        � � � � Improved cost performance

•        � � � � Direct reuse with existing heat sinks

•        � � � � The stamped wire clip allows improved front side bus routing due to smaller clip mounting holes

•        � � � � Both clips provide retention force directly above the chip
