This surface mount Black Plate was designed for use with Intel's Core i7 and Xeon 5 LGA 2011 (Sandy Bridge) CPU processors. The contacts have solder balls for surface mount onto the PCB. A hex ball array provides for a stronger housing and allows for a smaller area for all 2011 balls. The integrated load mechanism (ILM) generates the Z-axis compression load. Robuster plate limits PCB bowing during compression.
Hex ball array gives the housing more strength and provides a smaller area for the contact array
