PRINTED CIRCUIT BOARD FOR OPTICAL WAVEGUIDES AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A printed circuit board for an optical wave guide and a manufacturing method thereof are provided to minimize the influence of stress applied to a circuit pattern. CONSTITUTION: An optical waveguide(60) is formed on the upper center of a base board(10) and includes a lower clad(60a), a core(60b), and an upper clad(60c). The core is formed on the upper center of the lower clad. The lower clad surrounds the upper side and lateral side of the core. A lateral substrate(80) is formed on the base substrate and includes a penetration hole(50) through which an optical waveguide passes and a first circuit pattern.
