Normally, this perforation is provided in a later state, same as are other perforations indicated and symbolizing 215 , 216 , 217, and 218, after folding and laminating has been carried out.
Upon folding, dielectric strip 9 , 84 , 598 , 605 insulatively separates crossovers 99 of conductive paths 90 and 91, for preventing short circuits between the latter.
