ABSTRACT:
A pin-assignment method is provided for use on an IC package to arrange pin connections. The pin-assignment method can allow an improvement in the electro-static discharge (ESD) protection capability for the IC chip packed in the IC package. Specifically, the pin-assignment method organizes the no-connect pins of the IC package into groups and then assigns each of the two pins that bound each no-connect pin group to be connected to a power bus of the IC chip. This allows for an increased ESD protective capability for the no-connect pins. Moreover, the pin-assignment method can simplify the wiring complexity of the IC package.
