TE Connectivity’s surface mount LGA socket was designed for use with Intel’s® Core™ i7
LGA 1366 processor. The contacts have .64mm diameter solder balls for surface mount
onto the PCB, while the top side provides a cantilever beam interface to the package. The
integrated lever mechanism (ILM) generates the Z-axis compression load. A robust bolster
plate helps eliminate PCB bowing during compression. The sockets are validated to Intel
Design Guides.
