A METHOD OF MANUFACTURING A PRINTED CIRCUIT BOARD FOR OPTICAL WAVEGUIDES

摘要

PURPOSE: A method for manufacturing a printed circuit board for an optical waveguide is provided to automatically correct the pattern matching using a laser process facility with an auto scaling function. CONSTITUTION: A lower clad layer(102) is formed on a base substrate(101). A core material is stacked or coated on the lower clad layer by dispensing or ink-jetting. A core layer(105) with a core pattern is formed by processing the core material with the laser. An upper clad layer(106) is formed on the lower clad layer and the core layer.
