Zero Insertion Force (ZIF) is a connection technology in which the plugging and unplugging process of the connection plug takes place without force, no compressive or tensile forces occur.
This technology is used in connectors and CPU sockets and is a further development of the Low Insertion Force technology (LIF). The Zero Insertion Force socket is a CPU socket into which chips can be inserted and also removed again without any force. Spring contacts in the ZIF socket ensure that the chip is locked in place. The chip can be removed again with a locking lever. The advantage of the ZIF socket compared to other socket designs is the gentler handling of the pins.
