| titleOfInvention | A multiple metal foil clad board suitable for drilling with a carbon dioxide laser and a printed wiring board using the same. |
| abstract | (57) [Problem] To obtain a metal foil clad board using a metal foil capable of drilling a through hole and / or a blind via hole when directly irradiating a carbon dioxide gas laser even if the metal foil surface is rubbed and scraped, A high-density printed wiring board using the same is obtained. SOLUTION: A multi-layer metal foil clad board comprising a copper layer and a nickel layer or a nickel alloy layer is preferably a metal foil clad board in which a metal foil formed such that the shiny surface is preferably a nickel layer or a nickel alloy layer is arranged. A printed wiring board formed by directly irradiating a carbon dioxide laser having an output selected from 5 to 60 mJ directly onto the shiny surface to form through holes and / or blind via holes. [Effect] A metal foil clad board capable of efficiently drilling through holes and / or blind via holes by direct irradiation with a carbon dioxide laser without defects and producing a high-density printed wiring board. Was completed. |
