Double-sided Circuit Board Features

Both sides of the two-sided circuit board have wiring. 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 via. The guide hole is a small hole filled with metal on the PCB, which can be connected to both sides of the wire. Because the area of the double-sided circuit board is twice as large as that of the single-sided board, Double PCB and because the wiring can be staggered (can be wound on the other side), it is more suitable for use in more complex than the single-sided circuit. Strictly speaking, double-sided circuit board is a very important board in a PCB board, his use is great, Double PCB to see a board PCB board is not double-sided circuit board is also very simple, I believe that friends on the single Understanding is completely able to grasp the double-sided circuit board is a single-panel extension, meaning that the single-sided line is not enough to go to the reverse, double-sided circuit board is an important feature is a vias. Simple point is double-sided line, both sides have lines! A generous is: double-sided board is a double-sided circuit board! Some friends will ask such as a board double-sided alignment, but only one side of the electronic parts, such a board in the end is a double-sided circuit board or a single panel? The answer is obvious, this board is a double-sided circuit board, Double PCB but in the double-sided circuit board plate mounted on the parts only.

Duplex circuit board drawing circuit diagram

1, there are a variety of dedicated PCB mapping software, such as Protel, etc., can draw drawing circuit diagram, multi-layer is aligned in the position, and there are holes between the layers of the line connected to achieve cross- Easy layout. Double PCB After the layout can be done by the professional system board into a specific circuit of the circuit board.

2, double-sided circuit board to reverse the schematic diagram of the circuit can be divided into two steps. The first step: first the main components such as IC and other symbols according to the location of the circuit board to the paper, the foot connection and external components appropriate layout and painting, complete the sketch. Double PCB Step two: analyze the principle, according to customary painting to the circuit diagram finishing. You can also use the circuit schematic software, line up the components after the connection, and then use its automatic typesetting function to organize.

Double-sided circuit board on both sides of the lines to accurately alignment, you can use the tweezers of the two tip positioning, flashlight transmission, multimeter multimeter suppliers to measure off and other methods to determine the solder joints and lines of connectivity and orientation, Double PCB if necessary Remove the components to observe the following line direction.
