ZIF

There are two main ways a display can be connected to a PCB. Some displays are solder-down, requiring fine pitch soldering to connect the tail to the contacts on the PCB. Others use Zero Insertion Force (ZIF) connection. With a ZIF connection, the tail of the display is simply slid into a connector. The tail should slide easily into the connector, thus “zero insertion force”. The connector has a movable piece that either swings down or pushes in, locking the tail in place.
