Product Overview
The 3M Chip Carrier Sockets, 8400 Series, are designed for reliable interfacing with chip carriers conforming to JEDEC outlines MO-047 for square and MO-052 for rectangular devices. These low-profile, four-row, through-hole sockets are compatible with automated loading equipment, featuring an open top design for unrestricted airflow and molded slots for easy device extraction. They are suitable for wave soldering processes. These sockets are RoHS Compliant, with specific compliance information available in the Regulatory Information Appendix (RIA) in the "RoHS Compliance" section of www.3Mconnector.com (RIA E1 and C1 apply).
Important Notice Regarding Tin Whisker Growth:
3M PLCC products are tin-plated on the contact wiping surface, a necessary feature for ensuring mated reliability as standard PLCC contacts are also tin-plated. Tin whiskers are an inherent characteristic of tin, and mechanical stressing can promote their growth. It is possible for the PLCC and PLCC socket to exhibit tin whisker growth after mating. 3M adheres to iNEMI plating recommendations, utilizing whisker-mitigating tin plating chemistry to reduce the likelihood of growth. Users should carefully consider the suitability of a PLCC socket for their specific application, taking into account the product application's lifespan and environment, including mechanical stresses, humidity, and thermal cycling, which are known to stimulate tin whisker growth.
