Every PCB, the foundation of electronic devices, must be coded and marked to enable complete traceability and quality control throughout the manufacturing process.There are several ways to mark PCBs, however, laser marking is the most efficient in our practice.
It delivers high contrast and exact marking, saves time and energy, and doesn't contaminate the PCB panel's solder connections or circuitry.
At our facility, for laser engraving of PCBs we use the CO2 marking laser NUTEK LMC-S3. This machine features a fiducial mark, a PCB orientation check function, a program-controlled conveyor width adjustment, and an inbuilt inverter for double-sided marking. The option to engrave design features such as a logo is also available with this system. Additionally, we recently acquired a new generation NUTEK LMC-5S lasers. They are made to mark PCBs as they move along the assembly line, speeding up production.
By scanning the QR code, all the manufacturing steps can be tracked, helping to assure the PCB is assembled in quality.
