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.
