Key Applications

Application Scenario Core Benefits & Output Mode Recommendation
PCB Fine Patterning (HDI Prototyping) Sub-20μm linewidth patterning for small HDI board samples; fiber-coupled mode for galvanometer scanning, spatial mode for small-panel exposure.
Microfluidic Chip Fabrication Precision structuring of polymer microchannels (width ≥50μm); spatial free-space mode ensures uniform irradiation of chip substrates without channel deformation.
Small-Format SLA 3D Printing High-resolution resin printing (layer thickness ≤50μm) for micro-components; fiber-coupled output delivers pinpoint energy to the print bed.
UV Micro-Curing Rapid curing of small-area adhesives/coatings (e.g., electronic component bonding); dual-mode switching adapts to batch and prototype curing tasks.
Lab Research Photopolymerization kinetics studies, fluorescence excitation, and material surface modification; compact design fits lab optical benches.
