Abstract
A land grid array includes a flat-plate connector plastic housing having a plurality of terminal grooves, and a plurality of terminals having a pair of contact points and disposed in the various terminal grooves, wherein the contact points serve as connecting structures between a circuit board and another circuit board, or between an integrated circuit and a circuit board. Each terminal is formed by bending an integral metal plate, and has a fixing portion, a flexible portion and a signal transmission portion. The terminal is capable of reducing overall stress, such that the signal transmission portion is easily deformed without leaving permanent deformation. Meanwhile, wiping motions by the contact points are performed between a circuit board and another circuit board, or between an integrated circuit and a circuit board for removing oxidized thin-films on contact surfaces involved.
