Notice: 3M PLCC products have tin plating on the contact wiping surface. Tin whiskers are an inherent characteristic of tin, and mechanical stressing can drive whisker growth. It is possible for PLCC and PLCC sockets to exhibit tin whisker growth after mating. 3M utilizes iNEMI plating recommendations with whisker-mitigating tin plating chemistry to reduce the likelihood of tin whisker growth. Users should consider the suitability of a PLCC socket based on their specific product application's lifespan, environment, mechanical stresses, humidity, and thermal cycling.
