Presented here is a laser marking system our engineers designed and built in 2020, specifically tailored for printed circuit boards (PCBs). Equipped with a CO2 laser mounted on a XYZ gantry, off-axis machine vision, barcode reader, and a conveyor, this advanced machine showcases remarkable capabilities.
The off-axis machine vision system plays a crucial role in achieving precision. By locating the board fiducials, it ensures that the markings align flawlessly in their designated locations. The camera’s strategic angle and distortion correction software enable accurate detection and verification of markings on the board.
The laser marking process begins by etching one side of the board with crucial information and identifications. Simultaneously, the system marks a barcode along the edge, serving as a reference for the marking of corresponding data on the bottom side once the board is flipped and re-entered into the machine. This seamless transition allows for continuous and uninterrupted production, optimizing productivity and minimizing downtime.
Flexibility and customization are at the core of this laser marking system’s design. Engineers can tailor the process to meet specific needs, whether it entails integrating seamlessly with existing databases, connecting to sophisticated Surface Mount Technology (SMT) lines, incorporating external board stackers and destackers, or adopting various board flipping configurations—this system can adeptly accommodate it all.
Engineers in the PCB manufacturing industry can rely on this cutting-edge laser marking system as a powerful tool to enhance their production processes. Its precision, speed, and adaptability provide a remarkable competitive edge, ensuring immaculate and reliable results in every batch.
Elevate your PCB manufacturing processes with this remarkable laser marking system—engineered to meet the most demanding requirements and deliver unrivaled performance, making it an indispensable asset in the world of advanced electronics manufacturing.
