Chinese PCB manufacturer tells you
What is the difference between a double-sided PCB and a single-sided PCB?
The difference between 1:
The single layer PCB is only on one side of the PCB, while the double Layer PCB can be connected between two sides of the PCB with holes through the middle.
The difference between 2:
Parameters of double-sided PCB double-sided PCB production and single-sided PCB in addition to the production process is not the same, but also one more copper sinking process, that is, the process of the double-sided circuit.
A. The single-sided printed circuit board usually adopts single-sided copper-clad laminate. The etched circuit pattern is made on the copper surface by means of screen printing or photogenic imaging, and the excess copper foil is removed by chemical etching to form the conductor pattern.
B. Double-sided printed circuit board has two layers of conductors, and the upper and lower through holes are connected by expensive holes.In printed circuit board processing, the perforated hole wall is plated with copper layer to make the upper and lower layers conductive, double-sided printed circuit board is usually double-sided copper foil laminate, screen printing or photoimaging method on the copper surface to produce corrosion resistance line graphics, through chemical etching to remove the excess copper foil to form conductor graphics.
Double-sided PCB and single-sided PCB can be basically distinguished from each other in appearance. Single-sided PCB is a circuit board with only one layer and a line layer, while double-sided PCB is a circuit board with two wiring layers and through holes in the middle, so this is the difference between single-sided and double-sided PCB.
