发明名称 Method of manufacturing printed circuit board having landless via hole
摘要 Disclosed is a method of manufacturing a printed circuit board having a landless via hole. Specifically, this invention provides a method of manufacturing a printed circuit board having a landless via hole without the upper land of a via hole using a photoresist (P-LPR) which is loaded in the via hole. Therefore, in this invention, since a circuit pattern is formed using only copper of a copper clad laminate, the width thereof is minimized, thus easily realizing a fine circuit pattern. Further, the landless via hole structure is applied, resulting in a highly dense circuit pattern.
