METHOD FOR PROVIDING A PRINTED CIRCUIT BOARD USING LASER ASSISTED METALLIZATION AND PATTERNING OF A SUBSTRATE, PRINTED CIRCUIT BOARD, AND SYSTEM COMPRISING A PRINTED CIRCUIT BOARD

摘要

A printed circuit is made by laser projection patterning a metal panel (1000)of a substrate, laminating a dielectric layer (1200) on the metal panel, laserirradiating the substrate to form vias (1400) in the substrate, laser activatinga seed (1510) coat on the substrate, washing the seed coat from an unpatternedportion (1620) of the substrate, forming a patterned build-up layer on the substrate,and etching away the metal panel for forming metal protrusions.
