	Low Insertion Force - Biocrawler (Site not responding. Last check: )
		Low Insertion Force (LIF) is a type of socket often used for PGA or SPGA integrated circuits (ICs).
		Most modern motherboard processor sockets are now Zero Insertion Force (ZIF) rather than LIF.
		The reason many motherboards are going to the ZIF style rather than the LIF style is because it became difficult to apply equal pressure onto a processor into a LIF port without the processor becoming misaligned in the LIF socket.

	Low insertion force card reader - Patent 4236667
		A low insertion force, handfed card reader is disclosed comprising a housing having a profiled passageway therein opening to a frontal side.
		It will be noted that insertion is freely achieved, as no contact between the contact tips 42 and the card has occurred through this point in the operating sequence.
		It will be appreciated that the operation of the subject card reader requires low insertion force since the card is substantially completely inserted before encountering resistance.

	ZIF - Wikipedia, the free encyclopedia
		ZIF is an acronym for zero insertion force, a concept used in the design of IC sockets, invented to avoid problems caused by applying force upon insertion and extraction.
		For an IC with hundreds of pins, the total insertion force can be very large (tens of newtons), leading to a danger of damage to the device.
		Low insertion force (LIF) sockets reduced the issues of insertion and extraction but the lower the insertion force of a conventional socket, the less reliable the connection is likely to be.

	Low insertion force - Wikipedia, the free encyclopedia
		Low-insertion-force sockets (LIF) are literally IC sockets specially designed so the insertion force is low.
		As the pin count increases (e.g PGA or SPGA vs DIP) low insertion force changes from something handy for chips that are changed frequently to an almost essential feature.
		The reason many motherboards are going to the ZIF style rather than the LIF style is because the higher pin count meant that even with a low insertion force design the overall insertion force of the huge numbers of pins becomes too high for the chip to be easily inserted and removed.
