PRINTED CIRCUIT BOARD AND MANUFACTURING METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a printed circuit board in which a thermo-setting solder resist ink is applied to a ground layer, and to provide a manufacturing method of the printed circuit board.SOLUTION: A printed circuit board of this invention includes: a base substrate; a via penetrating through the base substrate; a circuit pattern formed on the base substrate; a ground pattern formed on the base substrate and used for reducing electromagnetic noise; a thermo-setting type heat radiation solder resist formed on the ground pattern and radiating heat; and an insulation layer which is applied onto the base substrate excluding the circuit pattern and the thermo-setting type heat radiation solder resist.
