itself is sufficient and no external downward force is required. The lever is then moved back, allowing the contacts to close and grip the pins of the IC. ZIF sockets are much more expensive than standard IC sockets and also tend to take up a larger board area due to the space taken up by the lever mechanism. Typically, they are only used when there is a good reason to do so.

The most important advantage of this system is that it does not require a mating half to be fitted to the wire ends, therefore saving space and cost inside miniaturised equipment. See

come in a number of widths (measured between pin centers), with 0.3 in (7.62 mm) and 0.6 in (15.24 mm) being the most common. To allow the design of programmers and similar devices that support a range of devices universal test sockets are produced. These have wide slots into which the pins

chips, particularly during development. These sockets tend to be unreliable, failing to grab all the solder balls. Another type of BGA socket, also free of insertion force but not a "ZIF socket" in the traditional sense, does a better job by using spring pins to push up underneath the balls.
