PCB laser marking applies permanent identifiers directly to suitable circuit board surfaces. Serial numbers, Data Matrix codes and other information can link an assembly to production and quality records without relying solely on an attached label.
The laser process must suit the board material and available marking area. Contrast, code size and surface response influence readability. Parameters should be validated to create the required mark without damaging the PCB or affecting features needed for assembly.
Evaluate board positioning, working area and cycle time within the intended production flow. Where available, camera verification can check whether the code meets the defined reading requirement. Code data should remain connected to the correct product record, including any rejected or reworked boards. Extraction and maintenance should account for the material processed during marking.
