Heat sinks mount via push-pin
ATS maxiFLOW heat sinks come with an integral push pin mounting system for fast, safe attachment of the heat sinks onto BGAs and hot components. Each unit comes with a pair of durable plastic or brass push. The pins run through opposite corners of the heat sinks and mount securely into 3.00mm holes in the pcb laid out in industry standard patterns. Plastic pins are lighter and non-electrically conductive; brass pins have added strength and durability for more rugged applications or thicker devices. An integral spring on each pin provides approximately 2 lbs of retention load, depending on the height of the component and the pcb thickness.
