According to the number of layers, PCB circuit boards can be divided into: Single-sided PCB board/double-sided PCB board/4-layer PCB board/6-layer PCB board/8-layer PCB board and other multi-layer PCB circuit boards.
Single-sided circuit board refers to a PCB board with only one side printed with wiring. Double-sided circuit boards are not much different from other multi-layer boards from the physical board, and the number of layers can only be identified after slicing with special technology.
Method 1: Distinguish by the “holes” on the PCB board. If you can see through most of the double-sided four-layer boards at a glance. If you can’t see through it, it is at least 6 layers or more.
Method 2: Export the Gerber data and view each layer of data in detail (such as: drilling layer, character layer, impedance layer, circuit layer, outer frame layer, etc.). Use the tool to hide the other layers except the circuit layer, and you can clearly see the number of layers on the PCB.
Method 3: In the absence of any PCB file, it can be identified by anti-reasoning copy software.
Method 4: Most factories can provide PCB slicing resolution reports. Through professional technology, the PCB board is cut open and placed on a special instrument for layer identification.
