| titleOfInvention | Manufacturing method of copper-clad laminate |
| abstract | PROBLEM TO BE SOLVED: To provide a method for manufacturing a highly visible metal-clad laminate. SOLUTION: For a copper-clad laminate, A) a step of preparing a dot pattern two-dimensionally distributed in a copper foil layer, B) a step of photographing a dot pattern through a polyimide layer and generating it as an output image, C. ) Divide the output image into the same number of dots as the dot pattern that is the input image, classify each dot into white dots or black dots, quantify the brightness for each dot to obtain the frequency distribution, and calculate the mean value and standard deviation. The visibility of the dots was evaluated by a visibility evaluation method including the step of performing and D) the step of calculating the signal-to-noise ratio based on a predetermined formula, and the visibility was evaluated by setting the amount of light within a predetermined range. In this case, it is manufactured so that the signal-to-noise ratio is 6 or more. [Selection diagram] None |
