Abstract: A socket connector (1) includes a dielectric housing (11) and a number of contacts (12) received in the housing. The housing defines top and bottom surfaces (111, 112) and a number of passageways (113) between the top and bottom surfaces. Each contact has a retention body (121) secured in a corresponding passageway and a contact portion extending beyond the top surface a first vertical distance for engaging with a corresponding pad (21) of an IC package (2). The body has an end projects beyond the top surface a second vertical distance. Protrusions (115) extend upwardly from the top surface toward the IC package, for supporting the IC package. Each protrusion projects the top surface a vertical height shorter than said first vertical distance but larger than said second distance. Thereby the pad can be prevented from electrically engaging the body of an adjacent contact when the IC package is pressed to mate with the connector.

Abstract: An electrical connector assembly (1) includes an LGA connector (2) and a pick up cap (3) mounted onto the connector. The connector defines a number of cells (26) for receiving a corresponding number of contacts (22). The pick up cap has a planar body (31) forming a plane top surface (300), which can be sucked by a vacuum suction device to move the connector assembly to a desired location on a PCB, and a bottom surface (301) opposite to the top surface. Several elongate passages (34) are defined in and through the planar body. Each passage extends aslant from the top surface to the bottom surface thereby preventing the contacts from dust. When curing adhesive film at high temperature, heated air can flow quickly through the passages and the cells to a bottom portion of the connector and reliable electrical connection between the contacts and the PCB are subsequently produced.
