Driven by the wave of digitalization, emerging industries such as 5G communications, smartphones, automotive electronics, and wearable devices are booming, placing higher demands on electronic components for miniaturization, integration, and high performance. As the core foundation of electronic products, Printed Circuit Board (PCB) plays a crucial role in electrical connection and structural support. To meet the demand for higher precision and more complex designs, PCB manufacturing processes have evolved, from single-layer boards to multi-layer boards and rigid-flex boards. The processes of depaneling and marking are becoming increasingly refined. Against this backdrop, laser technology, especially PCB laser cutting and laser marking, is gradually shifting from a “supporting role” to the “leading role,” injecting strong momentum into the PCB industry’s upgrade.
However, traditional methods for PCB cutting and marking still widely use mechanical tools, die-cutting, or inkjet marking. While these methods have low initial investment costs, their limitations are becoming more apparent. Mechanical cutting causes issues like stress concentration, dust pollution, burrs, and equipment wear, which can easily damage precise circuits and affect product reliability. Traditional inkjet marking tends to fade in high-temperature, high-humidity, or corrosive environments, failing to meet increasingly strict requirements for quality traceability and brand anti-counterfeiting. Moreover, the growing trend of PCB product diversification and personalization means that traditional processes lack flexibility and incur high line change costs, making it difficult to adapt to small-batch, multi-batch orders. This severely restricts the production efficiency and delivery capability of PCB manufacturers.
The rise of laser processing technology provides an effective solution to these challenges. Laser cutting is a non-contact thermal process that requires no consumables or mechanical wear, achieving stress-free, burr-free, and ultra-high precision cuts. It is particularly suitable for high-precision materials like FPC (Flexible Printed Circuits), ceramic substrates, and cover films. Laser marking, on the other hand, uses high-energy laser beams to create permanent marks on the PCB surface, such as QR codes, barcodes, serial numbers, or patterns. These marks are highly scratch-resistant and stable in various environments, and can achieve high-speed online marking with database integration for intelligent traceability systems. Particularly, UV lasers, with their “cold processing” characteristic, significantly reduce the impact on heat-sensitive materials, and are widely used in semiconductor packaging and precision electronic components.
