Heat sinks feature push-pin mounting

The maxiFLOW heat sinks feature an integral push pin mounting system for fast, safe attachment of the heat sinks onto BGAs and other hot components. Each heat sink comes with a pair of plastic or brass push pin. Plastic pins are lighter and nonelectrically conductive, while brass pins have added strength and durability for more rugged applications or thicker devices.

The pins run through opposite corners of the heat sinks and mount into 3.00-mm holes in the PCB laid out in industry-standard patterns. They are available in sizes ranging from 37.4 x 37.5 x 10.0 mm to 41.4 x 45.75 x 24.5 mm. The integral spring on each pin provides about 2 lbs of retention load,. Tests on the heat sinks with an airflow rate of 100 lfm show that device junction temperatures can be reduced by more than 40% below the temperatures achieved using conventional straight-fin heat sinks.
