CPU socket
A CPU socket is a physical interface on a computer motherboard where a central processing unit (CPU) can be installed.
CPU sockets can be made in two different main types: PGA sockets and LGA sockets.
Manufacturing[edit]
CPU sockets can be injection molded. The socket is injection molded, then the pins are inserted. Then, solder balls are applied to the bottom of the pins. Afterwards, a cap is added to the top for pick-and-place.[1]
An injection molding machine that can be used is a Fanuc Roboshot S2000iA.[1]
Materials[edit]
Intel recommends a thermoplastic or equivalent with UL 94 V-0 flame rating capable of withstanding 260 °C for 40 seconds.[2]
Celanese's Vectra LCP and Zenite LCP are advertised as suitable materials for injection-molded CPU sockets.[3] They are specifically designed for CPU sockets.[1] For example, Zenite 5145L.[1]
Other materials that can be used include Vectra FIT30 and Vectra E488i.[1]
E488I, FIT30, and 5145L have been used by Lotes to manufacture LGA 2011 sockets, also called Socket R.[1]
Companies[edit]
A company that has made CPU sockets is TE connectivity.[4]
Lotes is one of the world’s major suppliers of CPU sockets, especially for Intel processors.[5]
- Foxconn Interconnect Technology (FIT)[1]
