    • A sheet for drilling is provided to be used for a cover plate providing a high-quality product when a printed circuit board is manufactured. A sheet for drilling is coated with an organic material layer, a metal layer, and an anti-slip layer. The organic layer provides a lubricant function. The metal layer is formed in adjacent to the organic material layer to endow the lubricant function. The anti-slip layer is formed at a remaining surface of the metal layer. The anti-slip layer has a composition identical to that of the organic material layer. The anti-slip layer includes polymer or co-polymer obtained by at least one monomers selected from ethylene, ethylene vinyl acetate, ethyl acrylate, andethyl meta acrylate. The anti-slip layer has a colored layer.
    • 提供了用于钻孔的片材,用于在制造印刷电路板时提供高质量产品的盖板。 用于钻孔的片材涂覆有有机材料层,金属层和防滑层。 有机层提供润滑功能。 金属层与有机材料层相邻地形成以赋予润滑剂功能。 防滑层形成在金属层的剩余表面上。 防滑层具有与有机材料层相同的组成。 防滑层包括通过至少一种选自乙烯,乙烯乙酸乙烯酯,丙烯酸乙酯和间丙烯酸乙酯的单体获得的聚合物或共聚物。 防滑层具有着色层。

    • A punching sheet is provided to improve an adhesion property between the sheet and a substrate, so that the slip phenomenon between layers is prevented. A punching sheet includes an organic material layer and a metal layer having a lubricant function. The slope of one surface of the metal layer is tested through a slip scheme using a slip tester. The surface of the metal layer is inclined at an angle of 20 degrees with respect to a slip time point for a cooper foil. The surface of the metal layer includes an anti-slip layer including composition different from that of the organic material layer. One of the organic material layer and the anti-slip layer having the lubricant function has a colored layer. The surface of the metal layer has an average illumination value of 0.3mum or more.
    • 提供冲压片以改善片材和基底之间的粘附性,从而防止层之间的滑移现象。 冲压片包括有机材料层和具有润滑功能的金属层。 金属层的一个表面的斜率通过使用滑移测试仪的滑动方案进行测试。 金属层的表面相对于铜箔的滑移时间点以20度的角度倾斜。 金属层的表面包括防滑层,其包含与有机材料层不同的组成。 有机材料层和具有润滑剂功能的防滑层之一具有着色层。 金属层的表面的平均照明值为0.3μm以上。
