The back of my brain sees hundreds of tiny little pins just waiting to get bent.
Fortunately I gather at some point they actually switched to slight protrusions on the socket that contact nearly-flat points on the CPU.
- ericd 13y agoYeah, they're just metal pads on the CPU now.
- astrodust 13y agoThis is the Land Grid Array (LGA) socket type (http://en.wikipedia.org/wiki/Land_grid_array http://en.wikipedia.org/wiki/Land_grid_array) where the pins are on the socket and the pads are on the chip. This supplants the Zero Insertion Force (ZIF) sockets (http://en.wikipedia.org/wiki/ZIF_socket http://en.wikipedia.org/wiki/ZIF_socket), those being a reworking of the Pin Grid Array (PGA) packaging (http://en.wikipedia.org/wiki/Pin_Grid_Array http://en.wikipedia.org/wiki/Pin_Grid_Array) which was a higher density version of the Dual Inline Package (DIP) standard (http://en.wikipedia.org/wiki/Dual_in-line_package http://en.wikipedia.org/wiki/Dual_in-line_package) used for the 80286 and prior chips.
- miahi 13y agoThe pins in the socket are actually more complicated. Every pin is actually a kind of spring[1], so it stays in contact with the CPU when it is pushed on them. They are not very hard to bend if you drop the CPU on them by mistake - but instead of a (maybe) unusable CPU you can have an unusable motherboard. The odds of unusable equipment is actually low, as most of the pins are just for power.
