Printed Circuit Board Registration Testing

摘要

A structure for determining misregistration of layers of a printed circuit board. A first conductive pattern is on a first layer of the printed circuit board. A second conductive pattern on a second layer of the printed circuit board. There is a hole through the first layer and the second layer of the printed circuit board. There is electrically conductive material in the hole. If the first layer and the second layer of the printed circuit board are registered properly, the first conductive pattern and the second conductive pattern are not electrically continuous with the conductive material in the hole. If either or both of the first layer and the second layer are a misregistered layer, the conductive trace on the misregistered layer is electrically continuous with the conductive material in the hole.
