ABSTRACT:
An LGA connector assembly (1) includes an LGA connector (2) and a generally rectangular pick-up cap (3) mounted onto the connector. The connector defines a number of passageways (212) for receiving a corresponding number of contacts (22). The pick-up cap has a first surface (300) engaged with a vacuum suction device and a second surface (301) opposite to the first surface, a plurality of vents (302, 303) disposed therethrough, and a plurality of recesses (310) formed adjacent to the vents on the second surface. The recess with blind cavity configuration and the vent are formed a gap-depth air vent therebetween along a direction of perpendicular to the pick-up cap, thereby permitting heated air to easily and uniformly flow therethrough during mounting the connector assembly onto a circuit board by SMT.
