Minimizing Nicks in Active PC Conductors

Protective dummy, i.e., non-functional, printed circuit (PC) conductors are provided around the periphery of an array of active, i.e., functional, PC conductors concurrently with the fabrication of the array.

The dummy conductors act as a strain relief for the photoresist used in the associated process(es). As a result, the nicks and voids, which would normally appear along the outer sides of the outside active conductors of an array not having the protective conductors, are transferred to the dummy conductors, thereby maintaining the integrity of the active conductors. This is particularly useful for PC boards fabricated with peel-apart conductive structures.
