The Single Site Passive Series is a passive heat sink subassembly that is modified to integrate with nearly any open top socket. The clamshell style design allows you to use your socket of choice, in conjunction with a passive heat sink solution from the premier thermal solutions provider in the back end test and burn-in marketplace. The subassembly is hardware mounted to the BIB, after socket assembly.
The Single Site Passive Series features include:

- Clamshell action and use
- Unique design results in true vertical approach to device-eliminates point loading on device during lid actuation and closure
- Low cost achieved through molded and extruded components
- Maximum ambient temperature 125°C
- Spring loaded, compliant, heat sink allows for even mating to DUT
- Heat sink to DUT force calculated for optimal thermal resistance*
- Thermal interface material supplied upon customer request
- Designed to meet your chamber slot to slot chamber spacing
* The thermal resistance of heat sinks are based upon a handful of variables.
These variables include:
- The area that is in intimate contact between the heat sink and DUT
- The force applied to the DUT by the heat sink
- The airflow of the ambient environment

The lid hinge is spring loaded, allowing for typical clamshell
rotational motion at the top of the actuation cycle. Final
motion to closure is directly vertical allowing for a planar
approach of pressure pad to DUT.
