什么是单面板,双面板,多层板,铝基板,阻抗板,FPC软板（What are single panels, double sided plates, multilayer plates, aluminum substrates, impedance plates, and FPC soft plates） First, what is a single panel? The single panel is on the most basic PCB, the parts are concentrated in one side, the wires are concentrated on the other side. Because the wires only appear on one side, we call this PCB the single panel (Single-sided). Because the single panel has many strict restrictions on the design circuit (because only one side, the wiring cannot cross and must move around the individual path), only earlier circuits use such boards; Single panel wiring diagram to Printing (Screen printing) based, that is, in the copper surface printed on the resistance agent, after etching, and then to prevent welding mark on the mark, and finally with punching processing way to complete the parts guide hole and shape. In addition, a small amount of diverse products are produced by photographic patterning of photosensitive resist. Two. What is double sided board? What is the double panel, see how a board is double sided and double sided definition, these questions I believe is very vague to some just engaged in PCB industry novice friends, often heard that a single panel, double-sided, multilayer board, aluminum plate, impedance board, FPC soft board, but not to distinguish, sometimes talk with customers are not confident enough, can not confirm whether it is correct to say that today we take these new friends to learn about how to confirm the double plate! The strict sense is a kind of double sided board PCB board is very important in the circuit board, his purpose is great, see a PCB board is double sided board is also very simple, I believe that friends of the single panel is fully grasp, double panel is a single panel extension, mean single panel the lines are not enough to go to the opposite, there are important characteristics of double panel is a via hole. In a simple way, there are two sides of the line
