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 285:
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

that requires very little (but not literally zero) force for insertion. With a ZIF socket, before the IC is inserted, a lever or slider on the side of the socket is moved, pushing all the sprung contacts apart so that the IC can be inserted with very little force - generally the weight of the IC

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.

disk drives (mostly drives in the 1.8-inch form factor). PATA hard drives with ZIF-style connectors were used primarily in the design of ultra-portable notebooks. They have since been phased out, as SATA has a relatively small-form-factor connector by default.
228:. Also, even with relatively small pin counts, each pin extraction is fairly awkward and carries a significant risk of bending pins, particularly if the person performing the extraction hasn't had much practice or if the board is crowded. 196: 232:(LIF) sockets reduce the issues of insertion and extraction, but because of its lower insertion force than a conventional socket, are likely to produce less reliable connections. 250:, allowing computer retailers and consumers to assemble motherboard/CPU combinations based on individual budgets and requirements.
