双面电路板主要用于解决模板的复杂设计和面积，在板两侧安装组件。

双面PCB在复杂的过程中解决传统的柔性电路，双PCB易于出现虚拟焊接，仅适用于缺缺的小电流，电路板的前后通过铜包层压板或铝 -作为基板通过蚀刻形成的导电层，特性是正导电层的导电层和背面设置有通过穿刺模式形成的通孔，在需要导电通过的位置。双PCB本实用新型采用刺穿，部件表面和导电层背面的电导率快速方便，双PCB可节省大量复杂的过程并提高生产效率。

双面PCB的两侧都有布线。但是，要使用电线的两侧，必须在双面之间具有相应的电路来连接。电路之间的“桥”称为引导孔（通过）。引导孔位于PCB上，填充或涂抹金属小孔，它可以与两侧连接导体。由于双面PCB区域大于单面板，双重PCB和由于接线可以彼此隔行（可以绕过另一边），因此更适合于比单个面板更复杂在电路上。在严格的意义上，双面电路板是一个非常重要的PCB板，他的使用非常大，看到一个板PCB不是双面PCB也很简单，我相信单一面板的朋友的理解是完全可以掌握，双面PCB是单面的延伸，双面PCB意味着单面板线路不足以转向对面，双面电路板还具有重要的特点有传导通孔。简单的点是双面步行线，双方都有线！ A word is: double-sided line of the board is double-sided PCB! Some friends will ask such as a board double-sided line, Double PCB but only one side has electronic parts, such a board in the end is double-sided PCB or single panel it? The answer is obvious, such a board is double-sided PCB, just on the double-sided PCB board on the plate on the parts. Multilayer circuit board to distinguish the PCB according to the number of wiring surface to determine the process of difficulty and processing prices, ordinary circuit board side-by-side line and double-sided line, commonly known as single-sided and double-sided PCB, Double PCB but high-end electronic products, due to product space design constraints, in addition to surface wiring, the interior can be superimposed multi-layer lines, production process, The production of each layer after the line, and then through the optical equipment positioning, compression, so that multi-layer lines superimposed on a circuit board.
