　　Manufacturing PCB circuit boards can be divided into multi-layer PCB circuit boards based on the number of layers: single-sided PCB board, double-sided PCB board, 4-layer PCB board, 6-layer PCB board, 8-layer PCB board, etc. Single-sided PCB board refers to a PCB board with only one printed circuit board. Secondly, double-sided PCB board is not much different from other multi-layer boards from the physical board, and can only be distinguished by special technology slicing. Is there any other method to distinguish the number of layers of double-layer 4-layer, 6-layer, 8-layer PCB board?

　　Method 1: Distinguish through the "holes" on the PCB board. If it can be seen through at a glance, it is mostly a double-sided four layer board. If it cannot be seen through, it is at least 6 layers or more.

　　Method 2: Export Gerber data, carefully examine each layer of data inside (such as drilling layer, character layer, impedance layer, circuit layer, outer frame layer, etc.), use tools to hide other layers except for circuit layer, and you can clearly see the number of PCB circuit board layers.

　　Method 3: In the absence of any PCB files, identification can be achieved through reverse inference board copying software.

　　Method 4: Most factories can provide PCB slice resolution reports, which can be cut and placed on dedicated instruments for layer identification through professional technology.
