Note on Tin Plating: 3M PLCC products are tin plated on the contact wiping surface. This is necessary for mated reliability, as standard PLCC contacts are also tin plated. Tin whiskers are an inherent characteristic of tin, and mechanical stress can drive whisker growth. It is possible for the PLCC and PLCC socket to exhibit tin whisker growth after mating. 3M follows iNEMI plating recommendations, which include whisker-mitigating tin plating chemistry to reduce the likelihood of growth. Users should consider the suitability of a PLCC socket for their specific application, considering lifespan, environment, mechanical stresses, humidity, and thermal cycling.
