All ATS pushPIN™ heatsinks feature pre-drilled holes for secure mounting to PCBs in industry standard hole locations. To meet application needs, pushPIN™ are available in both durable plastic and brass. Plastic pins are lighter and non-electrically conductive. Metal pins have added strength and durability for more rugged applications or thicker boards. All pushPIN™ heatsinks feature flexible barbs that lock securely in PCB holes.
