New Solutions for FPC Laser Cutting Machine

With the explosive growth of 5G and new energy vehicle industries, FPC (flexible printed circuit) processing faces stringent demands for “high precision, rapid iteration, and low damage.” Traditional mechanical stamping processes are gradually being phased out due to high mold costs, insufficient precision (only ±50μm), and the tendency to produce burrs. A new laser cutting solution has emerged to address these challenges.

This solution, centered on 355nm ultraviolet lasers and femtosecond lasers, achieves a non-contact “cold processing” breakthrough:

Through dynamic power adjustment technology, it adapts to complex structures such as rigid-flex PCBs. Energy levels are set at 80-100 mJ/mm² for rigid areas and reduced to 50-60 mJ/mm² for flexible areas, increasing yield from 75% to 95%. Coupled with an intelligent vision compensation system, the focused spot size is reduced to within 15μm, achieving a positioning accuracy of ±5μm, meeting the requirements for 0.2mm ultra-fine line cutting, a three-fold improvement over traditional processes.

Simultaneous upgrades in efficiency and flexible production are the core advantages of this new solution. Multiple lasers working in conjunction increase efficiency by 4-6 times compared to stamping presses, and zero-gap layout improves material utilization by more to than 30%. Direct import of CAD files enables rapid prototyping in 30 minutes, shortening the new product development cycle by 70%. Femtosecond laser technology further controls the heat-affected zone to within 10μm, perfectly suited for high-frequency materials such as LCP, making it the preferred choice for 5G base station and automotive FPC processing.

In the consumer electronics field, 20W ultraviolet laser equipment achieves a daily production capacity of over 50,000 pieces; in the automotive electronics field, the failure rate is reduced to 0.03% in environments ranging from -40℃ to 125℃. This new solution, which combines high precision, high efficiency, and environmental friendliness, is driving the transformation of FPC processing from “mold-dependent” to “intelligent and flexible,” becoming a core support for the upgrading of the electronics manufacturing industry.
