Features and Benefits
• New unique wire clip design allows for complete reworkability
after assembly
• Configurations are available for a wide range of BGA package
sizes in any thickness up to 3.0mm
• 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 performance
Solder anchors are sold separately

Thermal Performance
*θn**θf
15.3 5.15
*Natural convection thermal resistance is based on a 75 °C heat sink temperature rise.
**Forced convection thermal resistance based on an entering 1.0 m/s (200 lfm) airflow.
Due to various heat dissipation paths within a BGA device, please test the heat sink in your application.
