PRINTED CIRCUIT BOARD AND METHOD FOR MANUFACTURING SAME

摘要

A printed circuit board includes a first electrically conductive circuit pattern, a substrate layer, an adhesive sheet, and a second electrically conductive circuit pattern, which are arranged in the above described order. The printed circuit board includes a single layer electrically conductive circuit area. The adhesive sheet defines a first opening spatially corresponding to the single layer electrically conductive circuit area. The adhesive sheet includes a first inner sidewall surrounding the first opening. The second electrically conductive circuit pattern defines a second opening spatially corresponding to the single layer electrically conductive circuit area. The second electrically conductive circuit pattern includes a second inner sidewall surrounding the second opening. The first inner sidewall and the second inner sidewall are not completely coplanar.
