PCB Laser Marking by Southern Machinery: Choosing the Right Laser Source for Traceability
Laser marking is now a hard requirement in PCB Assembly — and the laser source you choose (CO2, fiber, green, or UV) determines whether your marks are legible, durable, and grade-A scannable on your specific substrate. This guide from Southern Machinery explains how the S-4545DT PCB laser marking machine selects the right source for FR4 PCB, FPC, and metal-shield surfaces, covering power class, service life, supported barcode types, double-side marking, and in-line CCD grade verification. Learn which laser source fits your production line and how MES-integrated, permanent marking reduces traceability defects, rework, and warranty exposure across automotive, medical, LED, and appliance electronics.
