Introducing Sockets and Hardware for LGA 1366 Processors Tyco Electronics' surface mount LGA socket was designed for use with Intel's(R) CoreTM 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.
