MANUFACTURING METHOD OF WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide the manufacturing method of a wiring board capable of simply manufacturing the wiring board at a low cost with high reliability because of a few joints between different materials, with ease of minute wiring, and with less wire resistance because of employing a high groove aspect ratio.

SOLUTION: The manufacturing method adopts a step wherein grooves and through-via holes are formed to an insulator sheet on the surface of which an exfoliable sheet is formed, conductor paste is filled into the grooves and through-via holes, and the exfoliable sheet is exfoliated.
