Abstract:
A method of manufacturing a printed circuit board, comprising:forming first resin layers of a solvated first resin on each of two faces of a metal plate, the first and second resin layers forming a continuous first resin matrix on each of the faces of the metal plate;attaching and selectively etching first metal foils on the first resin layers;forming second resin layers of the solvated first resin on the first metal foils and the first resin layers;attaching second metal foils on the second resin layers and opening a first connection holes in the second metal foils and, the second resin layers;forming first plated layers on the second metal foils and in the first connection holes; andselectively etching the second metal foils and the first plated layers.
