With 108,000 possible configurations, Advanced Thermal Solutions, Inc. (ATS) now provides the widest choice of push pin-mounted heat sinks for cooling thousands of BGAs and other hot components.
More than 200 aluminum ATS heat sinks are now available with push pin mounting. The lightweight heat sinks include straight fin, cross-cut, and ATS maxiFLOW™ spread fin geometries. Over 100 fine pitch heat sinks are available for effective cooling in high airflow conditions. Another 100 sinks have coarse pitch fins, with wider fin spacing for low velocity airflow. The range of heat sinks is sized for cooling hot components in lengths from 25-70 mm.
Each ATS push pin heat sink features pre-drilled holes for secure mounting to a PCB in industry standard hole locations. To match the application, durable plastic or brass push pins are available in lengths from 9-20 mm. Plastic pins are lighter and non-electrically conductive. Brass pins have added strength and durability for more rugged applications or thicker devices. The push pins feature a flexible barb to lock into pre-drilled holes.
The compression springs on the pins add the needed force for secure attachment and effective heat transfer. These springs are available in 21 different sizes to achieve the precise force required for optimum heat sink performance on different PCBs.
ATS push pin heat sinks are pre-assembled with phase-changing thermal interface material for increased performance. Double-sided thermal tape or no TIM options are available to meet application specific requirements
