The Precision Fabrication Process
Stage 1: Material Selection & Incoming Inspection
Premium materials selected based on your requirements—FR4, High-TG, Rogers, or specialty materials. Every material shipment undergoes incoming inspection: certification verification, dimensional measurement, and quality documentation review.
Stage 2: Precision Imaging
Circuit patterns are produced using advanced photo imaging equipment. High-resolution imaging ensures accurate pattern transfer with precise registration between layers.
Stage 3: Precision Etching
Controlled etching processes maintain consistent trace dimensions. AOI inspection verifies trace integrity and detects any defects.
Stage 4: Precision Drilling
Advanced drilling equipment with automated depth control ensures accurate hole positioning. Drill quality is verified through measurement and visual inspection.
Stage 5: Precision Lamination
Lamination under controlled temperature and pressure ensures uniform material properties and consistent dielectric thickness.
Stage 6: Surface Finishing
Precision application of surface finishes—ENIG, HASL, OSP, Immersion Silver, Immersion Tin, Gold Plating—with thickness verification.
Stage 7: Precision Testing
100% electrical testing; impedance testing (TDR); AOI inspection. For low volume PCB assembly, flying probe testing provides cost-effective verification.
Stage 8: Final Quality Inspection
Comprehensive dimensional verification; visual inspection; packaging verification.
