3.3.1Backplate Assembly

The backplate is mounted on the backside of the motherboard and enhances local stiffness to support shock and vibration loads acting on the heat sink. The backplate assembly prevents excessive motherboard warpage in the area near the processor. Without a backplate, excessive warpage could cause serious damage to electrical connections of the processor socket and integrated circuit packages surrounding the processor. The backplate also serves as a stiffener plate for the LGA socket.

The reference backplate is made from a 1/16-inch, hard-milled steel, has an overall thickness of 0.138 inch (3.5 mm), including stiffening ribs, and has a mounting-hole pitch of 3.5 inches. To accommodate the capacitors on the backside of the board, there is a square hole in the center of the backplate.
