How should electronic manufacturers choose a suitable PCB laser marking machine ？
1、 Clear requirements and scenario usage positioning identification content: Do you need to print text, QR codes, barcodes, graphics, or serial numbers? Accuracy requirements: such as small characters (below 0.1mm) or high-density QR codes (such as QFN component markings). Marking speed: What is the production line speed? Do you need high-speed online marking? Environmental requirements: Is the PCB type used in a dust-free workshop, high temperature and high humidity environment, or outdoors? Is the board type painted with white or black paint? Is the marking position single-sided or double-sided? 2. Comparison of core technical parameters. Selection of marking technology: Laser marking machine: Advantages: high precision, permanent marking, no consumables, suitable for multiple materials (can cut carbide markings or color comparisons). Applicable scenarios: PCBs, ceramic substrates, QR codes/serial numbers that require long-term traceability. Attention: Fiber laser (suitable for metal and copper-clad laminates), UV laser (suitable for plastic/flexible boards), CO2 laser (for boards without white oil blocks). Inkjet printer: Advantages: Color marking, suitable for temporary information (such as date/batch). Limitations: Consumables (ink) are required, markings are prone to wear and tear, and are not suitable for high-precision requirements. Key parameter matching accuracy: It needs to reach the level of 0.01mm (such as QFN component labeling). Speed: Online marking requires ≥ 1pcs/s (depending on the production line rhythm). Wavelength/power: Fiber laser (1064nm) is suitable for metals; UV laser (355nm) is suitable for plastic/copper surfaces; Carbon dioxide laser (10640nm) is suitable for non-metallic materials; Work format: Based on PCB size (e.g. maximum coverage of 450 × 450mm).
3、 Does compatibility and scalability automation integration need to be integrated with the production line? MES system integration. Is it necessary to equip a lower plate machine for online or offline work. Software Function Data Interface: Supports importing serial numbers into Excel or databases, or generating dynamic data in real-time (such as timestamps). Marking template: Supports vector graphics (DXF/AI) and automatic segmentation of large files (such as large format PCB panels). Traceability system: Can it be integrated with factory MES/ERP to achieve data binding and querying. Maintenance and consumables costs: Laser equipment requires regular maintenance of lenses, and inkjet requires ink consumption. Failure rate: Modular design is preferred, with long lifespan of core components (such as lasers) to avoid frequent shutdowns. After sales service: supplier response speed, spare parts inventory, and technical support capabilities. 4、 Supplier evaluation and testing case investigation require providing industry cases to verify equipment stability. Visit supplier factories, assess their scale, and test the actual marking effect (such as character clarity and edge sharpness) through machine testing. Sample testing provides our own PCB samples for marking testing, with a focus on observing: software stability and ease of use (the software conforms to the habits of SMT users, such as software operation similar to milling cutters and splitting machines); Accuracy consistency (offset of multiple marking positions); Code level (painted white, usually reaching A level). Price and cost-effectiveness should avoid blindly pursuing big brands. The core lasers are mostly purchased externally and then integrated with software and hardware by the manufacturer's system. Be wary of hidden costs (such as the lifespan of ultraviolet lasers, which can require a warranty period of at least 18 months). 5、 Recommended selection strategy with low budget cost: Choose a fixed PCB laser marking machine with a laser head, which has a larger marking range and lower laser coding level. Moderate budget: Choose a mobile PCB laser marking machine with a laser head, without flip board, and can print codes up to A-level. Adequate budget: Choose a mobile PCB laser marking machine with an optical head, equipped with a flip board, to achieve double-sided marking, and the coding can reach up to A-level. There are three steps for electronic manufacturers to choose a PCB marking machine: requirement analysis (QR code size, whether to brush white oil, maximum PCB size, whether double-sided marking is needed); Technical matching (laser type, power, software function); three Risk avoidance (testing and verification, on-site inspection of supplier qualifications, after-sales support).
