Claim Text:
1. A method of fabricating printed circuit boards, the method comprising: fabricating a set of signal wiring conductors onto a set of areas of an electrically insulating substrate such that a number of the set of signal wiring conductors terminates proximate to a dicing channel separating each of the set of areas from others of the set of areas in which the set of areas are to be formed into a set of printed circuit boards; fabricating a set of plated through holes through a number of the of the set of areas such that a number of the set of plated through holes connects to the number of the set of signal wiring conductors; and separating the set of areas in the electrically insulating substrate along a set of singulation lines to form the set of printed circuit boards, wherein a number of the set of singulation lines intersects with the number of the set of plated through holes to expose an exterior edge of the number of the set of plated through holes during singulation.
