## FEATURES AND BENEFITS 

- New unique wire clip design allows for complete reworkability after assembly without damage to the BGA package or PC Board 

- Configurations are available for a wide range of BGA package sizes 

- Minimal PC Board real estate is required for mounting 

- Solder Anchors provide the most rugged mounting in the industry 

- Each Heat Sink utilizes a phase change pad as the interface for optimal thermal performance. 

Drawing represents those heat sinks requiring 2 solder anchors 

Solder Anchor Sold Separately **Part #  D057** Solder anchors must be soldered to PCB prior to attaching the heat sink clip Consult P.C. Board Hole Pattern for number required
