Important Notice Regarding Tin Whiskers: 3M PLCC products have tin-plated contact wiping surfaces, which is necessary for reliable mating with standard tin-plated PLCC contacts. Tin whiskers can be an inherent characteristic of tin. Mechanical stressing of the tin surface can drive whisker growth. It is possible for PLCC and PLCC sockets to exhibit tin whisker growth after mating. 3M adheres to iNEMI plating recommendations, utilizing whisker-mitigating tin plating chemistry to reduce the likelihood of tin whisker growth. Users should evaluate the suitability of PLCC sockets for their specific applications, considering product lifespan, environment, mechanical stresses, humidity, and thermal cycling, as these factors can stimulate tin whisker growth.
