18. Design of IC sockets ได้แก่ ZIF , LAG,PGA

19. ZIF 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. 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 (tens of newtons), leading to a danger of damage to the device or the PCB. Also even with relatively small pin counts each 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 the board is crowded), as can be seen with the unpopular front-loading mechanism of the Nintendo Entertainment System. Low insertion force (LIF) sockets reduce 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. * ปัจจุบัน ค่ายบ้างค่ายที่ผลิตเมนบอร์ดก็เลิกใช้ socket ก็เลิกใช้ไปแล้ว ZIF เป็น socket ที่ช่วยป้องกันการเปิดขา cpu ที่นำเข้าบิดงอหรือหักได้

21. LAG The LGA is used as a physical interface for microprocessors of the IntelPentium 4, Intel Xeon, Intel Core 2, Intel Core i7 and AMDOpteron families. Unlike the pin grid array (PGA) interface found on most AMD and older Intel processors, there are no pins on the chip; in place of the pins are pads of bare gold-plated copper that touch pins on the motherboard. While LGA sockets have been in use as early as 1996 by the MIPSR10000 and HPPA-8000 processors, the interface did not gain widespread use until Intel introduced their LGA platform starting with the 5x0 and 6x0 sequence Prescott core Pentium 4 in 2004. All Pentium D and Core 2 desktop processors currently use an LGA socket. As of Q1 2006 Intel switched the Xeon server platform to LGA starting with the 5000-series models. AMD introduced their server LGA platform starting with the 2000-series Opteron in Q2 2006. AMD offers the Athlon 64 FX-74 on socket 1207FX through ASUS's L1N64-SLI WS motherboard as the only desktop LGA solution in the desktop market from AMD currently.

22. The most common Intel desktop LGA socket is dubbed LGA 775 (Socket T) while the server variant is dubbed LGA 771 (Socket J). However, the new Intel Core i7 family uses the LGA 1366 (Socket B) socket. Intel supposedly decided to switch to an LGA socket because it provides a larger contact point, allowing, for example, higher clock frequencies. The LGA setup provides higher pin densities, allowing more power contacts and thus a more stable power supply to the chip. Motherboard vendors have complained that LGA packaging was introduced solely to move the burden of bent pin problems from Intel to the electronics vendors. The AMD server LGA socket is designated Socket F (LGA 1207) Similar to Intel, AMD decided to use an LGA socket because it allows higher pin densities. The required size of a 1207-pin PGA would simply be too large and would consume too much space on motherboards. นิยมใช้การมากในรุ่น cpu ใหม่ๆ หรือ ณ ปัจจุบัน
