As far as it is concerned, with the launch of new products, the demand for printed circuit boards remains high. In the global industrial chain, the PCB industry can be said to have a pivotal position.

CCL (Copper Clad Laminates) is used as the basic material source of printed circuit boards. Its production process is to impregnate epoxy resin into glass fiber cloth, and then process it to form an adhesive film (A) with a certain thickness. For insulation and support between components, traditionally, as shown in Figure 1, manual weighing is mostly used to measure the thickness of the adhesive film. After completing the processing of the adhesive film (A), the operator (C) Use the cutting tool (T) to cut a specific area and weigh it to get the thickness value of the adhesive film (A). Angle, cutting proficiency, and even the broken state of the adhesive film (A) after cutting will affect the results of thickness measurement after cutting. Furthermore, when cutting the adhesive film (A), it is necessary to use the CCL preparation machine Offline operations are performed, and the thickness cannot be measured online to correct the relevant parameters of the CCL preparation machine in real time. On the other hand, it is difficult to obtain relevant information on the uniformity of epoxy resin impregnated in glass fiber cloth by traditional methods. In addition, in order to solve the above problems, a method of measuring thickness using laser has also been developed, but the laser spot is often too small, and the surface of the adhesive film has different roughness to cause fluctuations in height, so that the small spot laser Errors in measurement results are also prone to occur.

Therefore, the present invention explains how to use innovative hardware design to effectively improve the errors of thickness measurement results caused by manual weighing and the shortcomings of inability to measure thickness in real time. It is still the developer of related industries. Issues that need to be overcome and solved continuously by related researchers.

In view of this, in order to improve the problems derived from the traditional measurement of the thickness of composite materials such as adhesive films, the inventors, with the assistance of their rich professional knowledge and practical experience, developed the present invention accordingly.
