Image Number 3 for United States Patent #6561818.
An electrical connector for connecting an electronic package (1) with a circuit substrate. A preferred embodiment of the electrical connector is a land grid array connector, which includes a parallelepiped-shaped insulative housing (2) and a plurality of retention arms (3). The housing includes four raised sides (21), and the retention arms are located in two contiguous raised sides. The retention arms include engaging portions (32) for resiliently abutting side walls of the electronic package. A material of the retention arms is different from a material of the housing. In the preferred embodiment, the material of the retention arms is metal. Thus the retention arms have superior resiliency, especially compared to the material of the housing.
