METHOD FOR FORMING A PRINTED CIRCUIT BOARD

摘要

PURPOSE: A method for forming a printed circuit board is provided to reduce distortion of a signal inputted to a signal line by suppressing noises applied to a power voltage and a ground voltage. CONSTITUTION: A wire connected to a signal, a power voltage, and a ground voltage is formed on a substrate(10). A signal line unit(20) includes a first signal line(21) and a second signal line(22). A power line unit(30) includes a first power line unit(31) and a second power line unit(32). The first power line unit includes a first power line(31a), a first via(31b), and a first plate(31c). The second power line unit includes a second power line(32a), a second via(32b), and a second plate(32c).
