Strictly speaking, PCB double-sided board is a very important type of PCB board in the circuit board. It has a wide range of uses, and it is easy to check whether a PCB board is a double-sided board. I believe that friends can fully grasp the understanding of single panels. Double panels are the extension of single panels, which means that the circuit of single panels is not enough to turn to the opposite side. Another important feature of PCB double-sided boards is that they have conductive holes.

　　Simply put, it means double-sided wiring, with lines on both sides! A summary is: A board with double-sided wiring is a double-sided board! Some friends may ask, for example, if a board has double-sided wiring but only one side has electronic components, is it a double-sided board or a single panel? The answer is obvious, such a board is a double-sided board, only parts are installed on the board of the double-sided board.

　　The advantages of manufacturing PCB double-sided boards are that the manufacturing cost is moderate and the application fields are wide. From household appliances to automobiles and medical devices, the figure of PCB double-sided boards can be seen. The top silkscreen top-level character dao, top soldermask top-level solder mask, top layer component surface circuit zhuanshu, bottom layer soldering surface circuit, bottom soldermask low-level solder mask, and bottom silkscreen low-level character in PCB double-sided board files, The PCB double-sided board does not have an inner layer, so the grounding wire is located on the top and bottom layers of the circuit, which requires higher wiring requirements. When handling the electrical layer, extra care is needed.
