These side-stackable sockets are now available in pitch packages from 0.50 mm through 0.80 mm, making them perfect for applications using BGA, LGA, and CSP. It has clearances from 0.5 to 2 mm depending on the pitch, and the socket bolt tabs are small. They can be soldered side by side, right onto the PC board. They use spring probe technology, with contact force of 12 to 15g per contact. Spring probe deflection is controlled by two chip guides in the interposer on the top of the socket. They come with an aluminum cover or an aluminum heatsink. An included nut driver tool makes sliding the lid on and off easy. The socket comes in two-bolt style for 15 mm or smaller packages, or four-bolt for 16-50 mm packages.
