| titleOfInvention | Backup sheet for laser drilling |
| abstract | A backup sheet that can be laminated and bonded to the back surface of a copper-clad plate at room temperature for irradiating a carbon dioxide laser to a thin copper-clad plate to open a through-hole for a small-diameter through hole. A resin composition to which a pressure-sensitive adhesive is added is adhered to the surface of a metal foil to form a backup sheet, which is placed on the back surface of a copper-clad plate and laminated at room temperature, and a carbon dioxide laser is applied to the copper-clad plate. Irradiate the surface to open a through hole. [Effect] By laminating at room temperature, there is no warping during laminating, small diameter through holes with good hole shape can be made at high speed with carbon dioxide laser, and thin copper clad plate can be folded even when peeling back-up sheet It is clear that it can be easily peeled off without being generated, and is excellent in workability and mass productivity. |
