Those you do not know the double panel knowledge
Do you know what is a double panel? What are the characteristics of it?
Double board is printed circuit board, printed circuit board, Kunshan circuit board, built and circuit boards, special circuit boards, special circuit boards, circuit board factory, circuit board factory, soft circuit board, soft board, flexible board, flexible circuit PCB, circuit boards, circuit boards, printed circuit board mills, aluminum plate, high-frequency board, PCB.
But to use the two sides of the wire, must be between the two sides have the appropriate circuit connection Caixing. The "bridge" between such circuits is called a through hole (through hole). The guide hole is a small hole filled with metal on the PCB, which can be connected to both sides of the wire. Because double-sided panels are twice as large as single-sided panels, and because cabling can be staggered (can be routed to the other side), it is more suitable for use on more complex than single-panel circuits.
Strictly speaking, the double panel is a very important board in a PCB board, his use is great, to see a board PCB board is not a double panel is also very simple, I believe that friends on the understanding of a single panel is completely Grasp the double panel is the extension of a single panel, meaning that the single-sided line is not enough to use to turn to the opposite, there are important features of double-sided panels are vias. Simple point is double-sided line, both sides of the line is a summary is: Double-sided board is a double-sided board Some friends will ask such as a board double-sided line, but only one side of the electronic parts, such a board in the end is a double panel or a single panel? The answer is obvious, this board is double-sided, but in the double-panel plate with the parts installed.
