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 of a substrate, laminating a dielectric layer on the metal panel, laser irradiating the substrate to form vias in the substrate, laser activating a seed coat on the substrate, washing the seed coat from an unpatterned portion of the substrate, forming a patterned build-up layer on the substrate, and etching away a metal plating forming metal protrusions.
