What is double sided PCB?

What does pcb double-layer board mean? The double-sided PCB with copper and metallized holes is a PCB double-layer board. This kind of circuit board will have wiring on both sides, but if you want to use two-sided wires, you must first have a proper circuit connection between the two sides. PCB can be classified according to the number of layers: single-sided double-sided multi-layer board. The electronic components of the single-sided board are concentrated on one side, and the wires are all on the other side. This is the PCB single-sided board. In terms of circuit design, the single-sided board has only one side and cannot cross and must go around its own path, so in general, the single-sided board is rarely used. The double-sided double-sided board has wiring on both sides, but there are also wires on both sides.

According to the number of layers, pcb can be divided into:
Single panel
Double panel
Multilayer board
Single panel
Electronic Components are concentrated on one side, and all wires are on the other side. This is the PCB single-sided board.
In terms of circuit design, the single-sided board has only one side and cannot cross and must go around its own path, so in general, the single-sided board is rarely used.

Double panel
There are wiring on both sides of the double-sided board, but there are also wires on both sides, and there must be a proper circuit connection between the two sides. The double-sided board solves the difficulty in the single-sided board because of the staggered wiring.
Double-sided boards have many advantages, such as convenient and simple wiring, less labor-intensive wiring, and shorter wiring length.
Multilayer board
There are more single or double-sided wiring boards on the multilayer board.
The number of layers on the board does not mean how many independent wiring layers there are. In some cases, empty boards are added.
