Important Notice Regarding Tin Whiskers:
3M PLCC products have tin-plated contact wiping surfaces, which is necessary for mated reliability with standard tin-plated PLCC contacts. Tin whiskers are an inherent characteristic of tin. Mechanically stressing the tin can be a known driver of whisker growth. It is possible that PLCC and PLCC sockets may exhibit tin whisker growth after mating. 3M follows iNEMI plating recommendations, including whisker-mitigating tin plating chemistry, to reduce the likelihood of tin whisker growth. Users should consider the suitability of a PLCC socket for their specific application, taking into account the product application's lifespan, environment, mechanical stresses, humidity, and thermal cycling, as these factors can stimulate tin whisker growth.
