LGA1155 Socket 3 LGA1155 Socket This chapter describes a surface mount, LGA (Land Grid Array) socket intended for the processors. The socket provides I/O, power and ground contacts. The socket contains 1155 contacts arrayed about a cavity in the center of the socket with lead-free solder balls for surface mounting on the motherboard. The contacts are arranged in two opposing L-shaped patterns within the grid array. The grid array is 40 x 40 with 24 x 16 grid depopulation in the center of the
