Problems solved by technology

The existing printed circuit board industry generally uses conventional dry film treatment methods and liquid brushing methods to transfer circuit graphics. This method is more suitable for larger printed circuit boards. Small and exquisite, developing in a more subtle direction, the graphic lines produced by the conventional line graphic production method in the prior art can no longer meet the requirements of small and clear
In order to solve the above problems, those skilled in the art have been doing a lot of research, but have not found a solution to the problem
