All ATS pushPIN™ heatsinks feature pre-drilled holes for secure mounting to PCBs in industry standard locations. To meet application needs, push pins 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 PCBs. All push pins feature flexible barbs that lock securely in PCB holes along with varied compression springs that will deliver the required pressure to meet thermal and mechanical requirements.
