PCB Industry
Industry Overview
The PCB (Printed Circuit Board) industry is the foundational backbone of modern electronics, enabling connectivity and functionality across 3C electronics, automotive, communication, medical, and industrial applications. As devices evolve toward miniaturization, high-frequency signal transmission, and multilayer integration, PCB manufacturing requires increasingly precise, efficient, and clean processing technologies.
Laser technology, with its non-contact, precise, and adaptive advantages, is rapidly becoming the go-to solution for drilling, cutting, marking, and surface treatment in advanced PCB production.
Industry Challenges
Micron-level precision in drilling micro-vias, especially for HDI and flexible PCBs
Delicate substrates (e.g., polyimide, LCP, CCL, ceramics) sensitive to heat and deformation
Complex board structures: Rigid-flex, multilayer, or ultra-thin materials require flexible tooling
Environmental regulations demand cleaner, chemical-free processes
Need for traceability and automated integration with smart production lines
