ABSTRACT:
A printed circuit board substrate is subdivided into sections, the boundary of each section being defined by notches which weaken the substrate and thereby permit the substrate to be fractured at the boundaries of the sections to permit the removal of a defective section. Printed conductors which electrically connect one section to another pass over the weakened substrate regions and when a section is removed, these conductors fracture at the boundary of the removed section. A replacement section may then be substituted for the removed defective section and its conductors connected to corresponding fractured conductors on the substrate.
