What (who) is Zero Insertion Force - definition

ELECTRICAL CONNECTOR THAT REQUIRES VERY LITTLE FORCE FOR INSERTION, OFTEN USED FOR IC AND CPU SOCKETS

ZIFS; Zero Insertion Force; ZIF socket

Zero Insertion Force

<hardware> (ZIF) A kind of socket for integrated circuits. A ZIF socket can be opened and closed by means of a lever or screw. When open, there the chip may be placed in the socket without any pressure at all, the socket is then closed, causing its contacts to grip the pins of the chip. Such sockets are used where chips must be inserted and removed frequently, such as in test equipment. They are more expensive and usually take up more space than conventional IC sockets. (1994-12-05)

ZIF socket

¦ noun a socket for electronic devices that is designed not to damage them during insertion.

Origin

acronym from zero insertion force.

Insertion (genetics)

ADDITION OF ONE OR MORE NUCLEOTIDE BASE PAIRS INTO A DNA SEQUENCE

Insertional mutation; Gene insertion; Insertion mutation; Genetic insertions; Genetic insertion

In genetics, an insertion (also called an insertion mutation) is the addition of one or more nucleotide base pairs into a DNA sequence. This can often happen in microsatellite regions due to the DNA polymerase slipping.

Wikipedia

Zero insertion force

Zero insertion force (ZIF) is a type of IC socket or electrical connector 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 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.
