This test used a GM-200 fiber laser to engrave a circuit-style graphic onto a PCB copper-clad board. The purpose was to verify whether the machine configuration could produce a clear circuit pattern on the material surface.
1. Test Goal
The goal was to test circuit pattern engraving on PCB copper-clad board using the GM-200 fiber laser.
The test focused on whether the engraved lines, pads, and graphic details could be clearly formed with the selected machine configuration.
2. Test Requirement
The required process was to engrave a circuit diagram-style design on PCB copper-clad board and save the tested laser parameters for later reference.
The test needed to confirm whether the setup could produce a clean and readable circuit-style effect on the sample.

5. Test Result
The engraving test was completed successfully, and the recorded result was good. The final sample showed clear circuit-style linework, visible pad details, and strong contrast between the engraved pattern and the PCB copper-clad board surface.

6. Test Conclusion
This test shows that the GM-200 fiber laser can engrave detailed circuit-style graphics on PCB copper-clad board. The result demonstrates clear line definition and readable decorative circuit details on the tested surface.
This type of process may support sample validation, circuit-style artwork, electronic-themed decorative panels, PCB material testing, and small-batch customization. Before batch production, the final parameter values should be confirmed with the same material, artwork file, lens setup, and marking software.
