ABSTRACT:
A PC board for mating with a card-edge connector having a selectively configured projecting tab which defines a desired insertion force profile to facilitate engagement. A portion of the projecting tab is notched to delay the initial contact from the internal spring contacts of the mating card-edge connector until a proportional amount of contacts have opened and wiped some of the PC board terminals first, and then to allow the remaining contacts to engage the notched portion. Initial insertion force is relieved in proportion to the PC board edge profile.
