    • A method for measuring amount of heat in metal foils wherein a small amount of laser light is directed to a metal foil and the amount of heat absorbed by the metal foil is measured by a sensor disposed on the back surface of the metal foil is disclosed. It is also disclosed an apparatus for measuring amount of heat in metal foils comprising a laser light introducing pipe having a light-reflective inner surface; a unit for placing a metal foil, which is subjected to measurement of amount of heat, on the bottom portion of the laser light introducing pipe; and a sensor for measuring amount of heat, which is in close contact with the back surface of the metal foil. A method for forming a small interlayer connection hole (through hole) in a printed circuit board wherein the amount of heat in a metal foil is measured for efficiently forming the interlayer connection hole and drilling with a laser can be conducted easily is disclosed. The resulting small interlayer connection hole (through hole) is excellent in quality and stable. An apparatus used therefor is also disclosed.
    • 公开了一种用于测量金属箔中的热量的方法,其中少量的激光被引导到金属箔,并且通过设置在金属箔的背面上的传感器来测量由金属箔吸收的热量。 还公开了一种用于测量金属箔中的热量的装置,包括具有光反射内表面的激光导入管; 在激光导入管的底部放置被测量热量的金属箔的单元; 以及用于测量与金属箔的背面紧密接触的热量的传感器。 公开了一种用于在印刷电路板中形成小层间连接孔(通孔)的方法,其中为了有效地形成层间连接孔和用激光钻孔来测量金属箔中的热量。 所得到的小夹层连接孔(通孔)质量优良且稳定。 还公开了一种用于其的装置。
