PCB circuit board is an important basic assembly part of electronic equipment. When making PCB circuit board, only when all aspects are considered clearly can we ensure that there will be no problems in the use of electronic equipment. So, what are the issues that should be paid attention to in the production of PCB circuit boards?
1. Consider the type of production
Circuit boards are divided into single-layer boards, double-sided boards, and multi-layer boards. The conductive pattern of the single-sided board is relatively simple, and only one side of the substrate has a conductive pattern. Double-sided panels have conductive patterns on both sides, and metal holes are generally used to connect the conductive patterns on both sides. The multi-layer board has many substrate layers and complex conductive patterns, and is more suitable for sophisticated and complex electronic equipment. Therefore, circuit board manufacturers should consider which type of circuit board to use when designing and manufacturing.
2. Consider the material of the substrate
The insulating laminate composed of polymer synthetic resin and reinforcing material can be used as the substrate of the copper clad laminate. There are many kinds of synthetic resins, and the reinforcing materials generally include paper and cloth. These materials determine the mechanical properties of the substrate, such as high temperature and bending resistance. Therefore, it is necessary to consider which material substrate to use when making a circuit board.
3. Consider the non-electrical technical indicators of the copper-clad board
The quality of copper-clad boards will directly affect the quality of circuit board production, and the quality of copper-clad boards is mainly reflected in non-electrical technical indicators such as peel strength, warpage, bending strength, and dip soldering resistance. Therefore, when making circuit boards, more consideration should be given to the non-electrical technical indicators of copper-clad boards.
