Close-up of a microprocessor land grid array CPU socket, on the upper side of a motherboard. This kind of socket lakcs pins (unlike ZIF sockets), which prevent it from breaking. The CPU is placed on a bed of flexible pins, against which the lever gently presses the CPU. The golden tips of the pins are shown. The pin bed is designed to meet three purposes: improved flexibility, a smaller pin tip regarding its spacing on a diagonal pattern, and good contact due to the gold plating. In the center of the image we can see a frame with tin contacts from other electric components. Field of view size: 24.0 x 36.4 mm (0.95 x 1.43 in)
