ABSTRACT:
An auxiliary device comprises a body with a planar surface for engaging with a vacuum nozzle. A pair of supporting portions perpendicularly extends from lateral edges of the body and forms a receiving space for receiving the assembled electrical connector. A stand-off portion is formed at a free end of each supporting portion. The height of the stand-off portion is less than the height (diameter) of the solder balls before soldering, and equal to the height of solder balls after soldering. Thus, the height of the solder balls is determined by the height of the stand-off portions and the planarity of the electrical connector is ensured by the stand-off portions. The provision of the stand-off portions also prevents solder wicking.
