1.09mm (.043") by 1.17mm (.046") Pitch LGA Socket 771 FEATURES AND SPECIFICATIONS Molex offers the 771-pin LGA CPU Socket for the Intel Dempsey Platform Processor Socket 771 is the first Computer Processing Unit (CPU) socket to be used on the server/workstation industry featuring the Land Grid Array (LGA) contact design. This socket is commonly known as Socket J, Socket 771 and LGA 771. This socket mates with the 771 LGA CPU package (gold pads) to form the processing unit of the application. Previous design uses the Pin Grid Array (PGA) socket or Micro-PGA socket (such as socket 604) mated with PGA CPU package. The 771-pin LGA CPU and Socket will replace the Socket 604 in Intel®Xeon® processor line. 47213 Vertical Surface Mount Molex’s high density LGA sockets features our low profile design, the shepard hook actuation lever and a flat or raised pick and place cover for the assembly process. All Molex’s LGA sockets comes with lead or lead-free BGA solder balls.
