PCB Laser Marking Machine

Machine Parameters:
The PCB laser marking machine’s compatibility with various PCB surface types, combined with its high-precision marking capabilities, makes it an indispensable tool in modern PCB manufacturing.
The ability to generate and mark QR codes is a significant feature of modern PCB laser marking machines. This allows for efficient traceability and identification of circuit boards throughout the production process.
In addition to QR codes, these machines can also implement barcodes for inventory tracking and management. This feature is particularly useful in high-volume manufacturing environments.
The precision of PCB laser marking machines enables the marking of characters and patterns with high accuracy. This is crucial for applications requiring detailed identification or aesthetic designs.
With 10-50 µm accuracy, these machines can handle complex designs and intricate patterns, making them ideal for a wide range of industrial applications, including those requiring copper surface laser marking. The integration of such technology with MES systems further enhances production efficiency.
By supporting various marking types, including QR codes and barcodes, and offering high precision, PCB laser marking machines play a vital role in modern electronics manufacturing, facilitating MES-integrated laser marking processes.
The latest generation of PCB laser marking machines boasts an array of sophisticated features that significantly enhance their functionality and efficiency in the PCB industry.
One of the standout features of modern PCB laser marking machines is their ability to integrate with Manufacturing Execution Systems (MES). This integration enables automated data retrieval, streamlining the marking process and reducing manual errors. By connecting directly to the MES, the laser marking machine can access critical product information, such as part numbers, serial numbers, and production dates, ensuring accurate and consistent marking.
