Double-sided Circuit Boards Both Sides Have Lines
- Sep 29, 2017 -


Double-sided circuit board is mainly to solve the complex design and area of the limit, on both sides of the board to install components.

Double-sided PCB to solve the traditional flexible circuit in the process of complex, Double PCB easy to appear virtual welding and only suitable for small current through the defects, the front and back of the circuit board is provided by copper clad laminate or aluminum-clad plate as the substrate through the etching formed conductive layer, The characteristic is that the conductive layer of the positive conductive layer and the back is provided with a pass hole formed by the puncture mode in the position where the conduction pass is needed. Double PCB The utility model is puncture-piercing, the conductivity of the component surface and the back of the conductive layer is fast and convenient, Double PCB which saves a lot of complicated processes and improves the production efficiency.

Both sides of the double-sided PCB have wiring. However, to use the two sides of the wire, you must have the appropriate circuit between the two sides to connect. The "bridge" between the circuits is called a guide hole (via). The guide hole is on the PCB, fills or spreads the metal the small hole, it may connect with the two sides the conductor. Because the two-sided PCB area is a lot larger than the single panel, Double PCB and because the wiring can be interlaced with each other (can go around the other side), it is more suitable for use in more complex than the single panel on the circuit. In strict sense, double-sided circuit board is a very important PCB board, his use is very large, see a board PCB is not double-sided PCB is also very simple, I believe that the Friends of the single panel of the understanding is completely can be grasped, double-sided PCB is the extension of single-sided, Double PCB It means that the line of single-sided board is not enough to turn to the opposite side, the double-sided circuit board also has the important characteristic is has the conduction pass hole. The simple point is two-sided walk line, both sides have the line! 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.
