See the development of an industry through printed circuit board

The name of PCB is also called aluminum board, high frequency board, ultra-thin printed circuit board and copper etched circuit board. There are many names in industry, but we generally call PCB printed circuit board. The miniaturization of printed circuit board plays an important role in the mass production of fixed circuits and circuit optimization, which is also the reason why printed circuit board can be widely used in the electrical industry.

The elements to be noted in the design and layout of printed circuit boards are as follows. Printed circuit boards are usually very low-cost. Components or jumpers may be required to skip the routing in the printed circuit board during circuit layout. If they are too many, double-sided boards should be considered. In small circuit design, double-sided panels can be used without even using PTH. PTH board is expensive and can only be used when circuit complexity and density are required. In the circuit layout design of printed circuit board, the number of wires on the component side shall also be minimized so that the required materials can be easily obtained.

On printed circuit boards, metal through holes are used only for electrical connections, not for mounting components. For economy and reliability, the number of holes should be kept to a minimum. When selecting one or both sides, it is important to consider the surface area of the part. The ratio relative to the total area of the printed circuit board is a reasonable and consistent ratio, which is very useful when installing components. Note that this usually refers to the area on one side of the panel.

When manufacturing a printed circuit board, a ratio between the pad diameter and the maximum line width is required. It enables you to create printed circuit boards, printed circuit boards, PCB factories, aluminum boards, high-frequency boards, printed circuit boards, etc. This also greatly reduces the cost of manufacturing printed circuit boards, because the production cost is low. In industrial production, our printed circuit boards are used in almost every electrical industry. The current achievements of printed circuit boards are related to the research and continuous optimization of their own R & D team, which is also the reason for the progress of modern science and technology.
