    摘要: A method for manufacturing a build-up multi-layer printed circuit board is disclosed which is used in the mother board of a computer, camera-incorporated VTRs, MCMs (multi chip module), CSPs (chip size package) or portable phones. In the build-up multi-layer printed circuit board of the present invention, an inner-layer connecting state is improved. The multi-layer printed circuit board is manufactured by sequentially stacking insulating resin layers and circuit conductor layers based on a build-up method. That is, a first insulating resin layer is necessarily made to undergo an exposure and a development so as to form a first via hole 122. Then a second via hole 124 which is larger than the first via hole 122 is formed on a second insulating resin layer, thereby forming a final V shaped photo via hole 120. Thus build-up multi-layer printed circuit board is manufactured.

    摘要: A method for manufacturing a build-up multi-layer printed circuit board is disclosed in which a YAG laser is used upon the formation of a via hole in the multi-layer printed circuit board, such that it can have the following advantages: the manufacturing process would become simple; the component packaging density and freedom for the design of the board would be improved; and a high speed of signal process would be ensured. The method for manufacturing a build-up multi-layer printed circuit board includes the steps of: forming a first printed circuit pattern on a copper clad laminate (CCL) by applying a general photo-etching process, the CCL having a copper foil on the one face thereof; stacking a resin-coated (on one face) copper foil (RCC) on the CCL with the first printed circuit pattern formed thereon, and heating and pressing this structure; irradiating a YAG laser to the board with said RCC stacked so as to form a via hole at a predetermined position by removing said RCC; carrying out an electroless and electro copper plating on the board with the via hole formed therein to form a plated layer; and forming a second printed circuit pattern on said plated layer to electrically connect the layers on which the first and second printed circuit patterns are formed.
