Abstract
A printed circuit board which is easily compensation adjustable. The PCB has compensator traces which are directly above and parallel to each other. Each of the layers of the PCB contains compensator traces which are aligned in a plane such that each of the compensating traces are aligned in a direction that is perpendicular to the respective planes. Thus, compensation can be effected in each of the various layers of the PCB by drilling one hole for each of the layers since the compensation traces are vertically aligned.
Claims27
A circuit board comprising:
- a first insulative layer containing a fist set of compensating traces in a first plane of said board;
- a second insulative layer containing a second set of compensating traces in a second plane of said board;
- wherein said first compensating traces and said second compensating traces are arranged over one another such that through-holes formed in said first and second insulative layers form identical holes in corresponding compensating traces of said insulative layers.
A method of compensating a printed circuit board comprising the acts of:
- forming a first insulative layer containing a first set of compensating traces in a first plane of said board;
- forming a second insulative layer containing a second set of compensating traces in a second plane of said board;
- wherein said first compensating traces and said second compensating traces are arranged above each other;
- and
- adjusting the compensation in each of said first and second insulative layers by drilling at least one hole through said layers, wherein said at least one hole penetrates corresponding compensating traces in said insulative layers.
