摘要 |
27 IMPROVEMENTS IN OR RELATING TO PRINTED CIRCUIT BOARDS A printed circuit board having holes provided with two or more electrical conductors on the surface of each hole. The conductors are circumferentially spaced apart around each hole so as to electrically isolate them from one another and each conductor is connected to an individual circuit line of the board. The conductors may be through-hole conductors. Alternatively, the holes are pin receiving holes for insertion of pins having two or more conductor lines for electrical contact with the conductors within the holes.
