PUSH PIN Push pins

Push pins are a popular mounting option that offers flexible and reliable attachment.
Several standard push pin sizes are available, while springs generate the appropriate mounting force/pressure. Alpha can design and produce the entire assembly, including the heat sink, push pins, springs, and thermal interface material.

5. Removal Procedure

Although push pin attachment is reworkable, we do not recommend using the same pins for multiple installations/removals. The pin ends may become deformed after multiple uses. Additional pins can be ordered as spares.
