Land grid array socket for electro-optical modules

摘要

An LGA socket suitable for electro-optical modules, such as transceivers having channels operable at 25 Gbit/s, or greater. A socket may include a socket body having a bottom side to face a printed circuit board (PCB), and a backstop on a top side to receive a leading edge of a module substrate. The backstop has an overhang to contact a first side of the module substrate when seated into the socket body. The socket further includes a first and a second row of electrical contacts, the first row being more proximate to the backstop than is the second row. Contacts extend through the socket body between the top and bottom sides and are positioned relative to the overhang to be compressed against contact pads on a second side of the module substrate by a torque applied to the module substrate about a fulcrum within the socket body.
