What is ZIF socket (zero insertion force socket)?
What is ZIF Socket (Zero Insertion Force Socket)? Short for zero insertion force socket, the ZIF socket was designed by Intel and included a small lever to insert and remove the computer processor. Using the lever, lets you add and remove a computer processor without any tools and requires no force (zero force).
What does ZIF stand for?
Zero insertion force. Zero insertion force ( ZIF) is a type of IC socket or electrical connector that requires very little 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 -...
What is the difference between Lif and ZIF sockets?
Low insertion force (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. Large ZIF sockets are only commonly found mounted on PC motherboards, being used from about the mid 1990s forward.
How do you remove a ZIF socket from a processor?
Processors that use a ZIF socket can easily be removed by pulling a small release lever next to the processor and lifting it out. The replacement processor is then placed in the socket and secured by pushing the lever in the opposite direction -- hence the phrase, "zero insertion force."
What is a ZIF socket and what is its purpose?
(Zero Insertion Force socket) A type of socket designed for easy insertion of pin grid array (PGA) chips. The chip is easily dropped into the socket's holes, and a lever is pulled down to lock it in. Pulling the lever moves the top plate of the assembly, pushing the pins into their contacts.
How do ZIF sockets work?
ZIF sockets normally work with a two-piece plastic housing. One piece affixes the contacts to the PCB and the second piece is cam activated with a lever or screw fitting to close the contact beam after the package under test is fully inserted.
What is a ZIF CPU socket?
A zero insertion force (ZIF) socket is a type of integrated circuit (IC) socket which is designed so that it requires no force at all, except gravity, to insert an IC into the socket.

Where is ZIF?
Zif (Arabic: زيف) is a Palestinian village located 7 kilometers (4.3 mi) south of Hebron. The village is in the Hebron Governorate in the southern West Bank. According to the Palestinian Central Bureau of Statistics, Zif had a population of 848 in 2007.
Is Intel PGA or LGA?
In the current market, Intel primarily uses the LGA technology whereas the AMD uses the PGA technology for their processors. The type of surface mounting a CPU uses also affects how the CPU socket is designed on the motherboard as well.
How does the ZIF socket hold the CPU in place?
3. ZIF sockets. ZIF (Zero Insertion Force): This is an evolution of the PGA, where the pins are carried by the microprocessor and inserted into the socket connectors. This mechanism is defined by not exerting any pressure (Zero Insertion Force) when installing or removing the processor from the socket.
How do I release ZIF connector?
Step 1 ZIF Connectors As the name implies, no force is needed to plug in or remove the cable. To disconnect the cable, use the tip of a spudger or your fingernail to flip up the small locking flap. Then, you can safely pull the cable out.
How is a chip installed in a zero insertion force ZIF socket?
These Zero Insertion Force (ZIF) sockets clamp onto a chip, making a good electrical connection, when you push the lever down. When you release the lever, it releases the chip. This allows you to repeatedly insert or remove a chip from the socket without damage to either.
What is a ZIF socket quizlet?
What is a ZIF socket? A special socket for inserting and securing a processor. Explanation. Newer motherboard use a ZIF (Zero Insertion Force) socket for inserting the processor. A ZIF socket has a lever or screw that opens to install the processor and closes to lock the processor into place.

What is ZIF wire to board connector?
ZIF wire-to-board connectors are used for attaching wires to printed circuit boards inside electronic equipment. An example would be the cable between the LCD screen and motherboard in laptops. The wires, often formed into a ribbon cable, are pre-stripped and the bare ends placed inside the connector.
What is a ZIF tape?
ZIF tape connections are used for connecting Parallel ATA and Serial ATA 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. Mini-SATA (mSATA) can be used where even smaller form factors are required.
What is a low insertion force socket?
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. Low insertion force (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.
What is the width of a DIP?
Standard DIP packages 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 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 drop allowing devices of differing widths to be inserted.
Why is ZIF socket important?
The ZIF socket was specifically designed to combat the issue of IC and pin damage due to insertion and removal.
What Does Zero Insertion Force Socket (ZIF Socket) Mean?
A zero insertion force (ZIF) socket is a type of integrated circuit (IC) socket which is designed so that it requires no force at all, except gravity, to insert an IC into the socket. This is achieved through the use of a slider or lever, which, when used, parts the spring-loaded contacts so that the IC can simply be placed on top of the socket with the pins meeting zero resistance as they are inserted into the openings between the contacts. When the lever or slider is moved back to its original position, the contacts close and grip the pins of the IC.
What is zero insertion force?
The zero insertion force socket is an important innovation used to protect an IC from being damaged during insertion or from frequent removal and reinsertion from a socket. Most IC sockets require that the IC be pushed into sprung contacts which grip the pins through friction, with friction also acting as resistance during insertion. For an IC with hundreds of pins such as a processor (CPU), the total insertion force can be very large, and it carries a large chance of damaging the IC or even the board. Even with ICs which have a relatively smaller number of pins, removing it from a regular socket carries significant risk of bending the pins.
What is ZIF connector?
The ZIF approach is also often chosen for connectors mating flat flexible cables to PC boards. In this case, the motivation is to make the connector as low profile as possible. The assembly operator opens the top of the connector, inserts the flat cable, then snaps the door closed on the top of the connector, generating the normal force needed for a reliable connection. This low profile connector design is well suited for laptops, tablets, and other handheld devices, especially for the flex circuits leading to displays, keyboards, and switches.
Why is ZIF connector so easy to use?
High mating cycle life is easy with ZIF connectors because they have no frictional mating wear. Frequently, the engagement handle can be activated with one hand, making it handy for locations where it is difficult to access with two hands or tools.
How does a ZIF handle work?
The handle for the ZIF mechanism can do double-duty by mating signal contacts inside a metal housing with suitable EMI containment shielding minimizing or eliminating electrical interference
Why do we use ZIF?
Test applications prefer ZIF approaches because they do not damage the device under test, especially important for high pin count devices.
What is the mate force of a Bendix connector?
In my last post, I wrote about the Bendix—Amphenol Bristle Brush connectors that had mating forces of 1.5 oz per contact. (To compare, most dual beam contact designs have mating forces in the range of 5 oz per contact.) High mating forces can be a problem for many connector designs, including IO connectors that are frequently mated and unmated, test sockets that mate hundreds or thousands of times per day, and especially for high pin count connectors. Many system designs can really benefit from using connectors designed to mate with zero insertion force.
Overview
Zero insertion force (ZIF) is a type of IC socket or electrical connector that requires very little 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. …
Design
A normal integrated circuit (IC) socket requires the IC to be pushed into sprung contacts which then grip by friction. For an IC with hundreds of pins, the total insertion force can be very large (hundreds of newtons), leading to a danger of damage to the device or the circuit board. 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 i…
Universal test sockets
Standard DIP packages 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 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 drop allowing devices of differing widths to be inserted.
Ball grid array sockets
ZIF sockets can be used for ball grid array 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.
