| titleOfInvention | Copper-clad laminate and circuit board |
| abstract | A copper-clad laminate and a circuit board that can maintain high visibility even when the amount of light changes are provided. A copper-clad laminate has a polyimide layer and a copper foil layer, and A) a step of preparing a dot pattern distributed two-dimensionally in the copper foil layer, and B) a dot through the polyimide layer. Step of capturing pattern and generating output image C) Dividing the output image into the same number of dots as the dot pattern of the input image, classifying each dot into white or black dots, and digitizing the brightness for each dot A step of calculating a frequency distribution and calculating an average value and a standard deviation; D) a specific expression using as parameters the average value of the luminance of black dots and white dots and the larger standard deviation of the luminance of black dots or white dots Assuming that the thickness of the polyimide layer is 38 μm by setting the light quantity at the time of photographing in the step B within the range of 1 to 8 mW / cm 2 by the visibility evaluation method including the step of calculating the signal to noise ratio based on When When evaluating the 認性 is the signal to noise ratio of 5 or more.
