    摘要: In a BGA package having electrically connected active balls and electrically disconnected dummy balls, the active balls are positioned in a radial direction at intervals of 90.degree. around the dummy balls. When a defect occurs in a solder joint, the package can be easily repaired by finding defective active ball; forming a repair hole by using a cutting means at a predetermined portion of the printed circuit board corresponding to a central position between the dummy ball and the defectively soldered active ball; inserting a solder paste injector into the repair hole to inject solder thereinto; and mutually connecting pad extensions of the dummy ball and the defective active ball with the injected solder. Therefore, the overall process can be simplified and its reliability can be improved.

    摘要: A lead assembly including a connector connecting structure having a plurality of separable portions and a plurality of leads. Each of the leads defined that they have a first end, a second end, a lead axis defined by the first and the second end, and an offset portion disposed between the first end and the second end. The offset portion being offset from the lead axis and adapted to be displaced downwardly with respect to the lead axis and bonded to a contact. The leads are preferably integral with the connecting structure. The connecting structure may be arranged outwardly of the leads, or may include parts interdispersed between groups of leads. The groups of leads may or may not correspond to individual units incorporating a microelectronic element.
