BALLMAP GENERATION METHOD FOR IC PACKAGE

摘要

A ballmap generation method for IC package is provided to generate automatically a ballmap by recording pad numbers of a pad list on the ballmap. An assignment process is performed to assign pad numbers of a pad list to a ballmap(S1). The pad list is defined by a user. A ballmap generation process is carried out to generate automatically the ballmap by using the pad numbers assigned to the ballmap. The assignment process further includes a process for identifying the pad numbers which are not assigned to the ballmap. The ballmap generation process includes a process(S2,S4) for recording the assigned pad numbers and position information to ball number boxes of the pad list, and a process(S5,S6) for recording pad names of the pad list on the corresponding pad number positions of the ballmap.
