Printed circuit boardWikipedia

Printed circuit boards were introduced to reduce the size, weight, and cost of parts of the circuitry. In 1960, a small consumer radio receiver might be built with all its circuitry on one circuit board, but a TV set would probably contain one or more circuit boards.

US6523252B1Coaxial cable, method for manufacturing a

The invention relates to a coaxial conductor having an inner conductor (S), an outer conductor (U) encasing the inner conductor (S) at least partly, and a dielectric (E) placed between the two. The coaxial conductor (K) is formed in a multi-layer circuit board (M) primarily by means of vias ( 2 a- 2 h ) and strip conductors ( 1 a- 1 i ).
