Single Side Board And Double-sided Circuit Board Distinction
Jun 23, 2017

Single Side Board history:

Single-sided printed circuit board is the early 1950s with the emergence of the transistor, the United States as the center developed products, when the main production methods to copper foil direct etching method for the mainstream. 1953 ~ 1955, Japan imported copper foil for the first time made of paper phenolic copper foil substrate, and a large number of applications in the radio. In 1956, the Japanese circuit board professional manufacturers, Single Side Board manufacturing technology immediately rapid progress. In the material, the early to paper-based phenolic copper foil-based, but because of the then phenolic material electrical insulation is low, poor heat resistance welding, twisting and other factors, one after another paper glow resin, glass fiber epoxy resin Development, the current consumption of electronic equipment required for a Single Side Board, almost using paper phenolic substrate board.

Single Side Board features:

The Single Side Board is on the most basic PCB, the parts are concentrated on one side, the wires are concentrated on the other side. Because the wires only appear on one side, we call this kind of PCB called single-sided. Because there are many strict restrictions on the design of the single-sided board (because there is only one side, the wiring can not cross and must be around the path), so only the early circuit to use such a board;

Single Side Board wiring diagram to network printing (ScreennPrinting), that is, the copper surface printed on the resistance agent, after etching and then to the resistance of the printed mark on the resistance, and finally punching processing to complete the parts of the hole and shape The In addition, a small number of diverse production of products, the use of photoresist to form a pattern of photographic

Double-sided (Double-Sided Boards) on both sides of the 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 on the PCB, filled with or coated with metal holes, it can be connected with the two 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 in more complex than Single Side Board circuit.

The following are the same as the "

Strictly speaking, the double panel is a very important board in the 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 Side Board is completely Grasp the double panel is the extension of a Single Side Board, meaning that the single-sided line is not enough to go to the reverse side, there are important features of double-sided panels are vias. Simple point is double-sided line, both sides have a line! A generous is: double-sided board is a double board! Some friends will ask, for example, 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 Side Board? The answer is obvious, this board is a double panel, but only in the double plate of the plate loaded on the parts only.
