In the conventional manufacturing process of the CCL (Copper Clad Laminates) as a base material source of the printed circuit board, epoxy resin is impregnated in glass fiber cloth, and then a prepreg a with a certain thickness is processed and formed to be used as an insulation and support between electronic components, as shown in fig. 1, a manual weighing method is mostly adopted for measuring the thickness of the prepreg, after the processing of the prepreg a is completed, an operator C performs cutting of a specific area by using a cutting tool T and scales the weight to push out the thickness value of the prepreg a, however, in the manual weighing process, the measurement of the thickness of the prepreg a is easily affected due to the cutting tool, the angle during cutting, the cutting skill, even the state of the cut prepreg a broken, and the operation of the CCL preparation machine is required to be performed offline, and the measurement of the thickness on-line cannot be performed to correct the relevant parameters of the conventional CCL preparation machine in real time, and on the other hand, the manufacturing method of epoxy resin is also difficult to obtain the relevant information on the uniformity of the glass fiber cloth. In addition, although a method for measuring thickness by using a laser has been developed to solve the above problems, the laser beam with a small light spot is too small, and the surface of the adhesive sheet has different roughness, which causes fluctuation of height, so that the laser beam with a small light spot is also prone to error of the measurement result.

Therefore, the present invention is directed to a method for effectively overcoming the defects of the conventional thickness measurement result error caused by manual weighing and the inability to measure the thickness in real time by means of innovative hardware design, and still needs to continuously overcome and solve the problems of the related industry developers and related researchers.
