Abstract
An electrical connector ( ) for connecting a land grid array (LGA) chip ( ) with a printed circuit board includes a housing ( ) and terminals ( ) received in the housing. Two cylindrical posts ( ) extend upwardly from diagonally opposite corners of the housing. Two recesses ( ) are defined in diagonally opposite corners of the LGA chip. The LGA chip is inserted into the LGA connector, with the recesses interferentially receiving the posts. Thus the LGA chip is securely mounted on the housing, with the posts and the recesses cooperating to precisely position the LGA chip on the LGA connector. This ensures that engagement between contact pads ( ) of the LGA chip and the terminals is highly accurate and reliable. Further, the posts are sized differently from each other, and the recesses are correspondingly sized differently from each other. Mismating of the LGA chip with the LGA connector is prevented.
