Abstract
Abstract The reinforcing fibers in a printed circuit board laminate are arranged in an ordered manner to leave fiber-free zones for the formation of holes. The holes may be oblong to enhance the connection to electrical leads of components mounted on the printed circuit board. The holes may be oriented with their long dimensions transverse to the side of an electrical component, and the electrical component may have its leads correspondingly oriented, to improve wiring flexibility and allow more direct wiring paths.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
71 words
A substrate of reinforced material, said substrate including: reinforcing members arranged with spaces therebetween at desired locations to permit the formation of holes in said spaces; and a material surrounding said reinforcing members and filling said spaces, said material being more easily penetratable at said spaces due to the absence of said reinforcing members than at other locations of said substrate to thereby permit the formation of holes in said spaces.
Claim 2
Dependent Claim
71 words
A substrate of reinforced material, said substrate including: reinforcing members arranged with spaces therebetween at desired locations to permit the formation of holes in said spaces; and a material surrounding said reinforcing members and filling said spaces, said material being more easily penetratable at said spaces due to the absence of said reinforcing members than at other locations of said substrate to thereby permit the formation of holes in said spaces.
