Full In-House Process Flow

Cutting to Packing — No Outsourcing

Every step of the double-sided and multilayer process happens inside our factories, monitored by ERP from engineering release to final packing.

  • Front end: engineering, CAM, cutting, CNC drilling (32 machines)
  • Plating & imaging: PTH / panel plating, dry film, LDI-class exposure, DES pattern plating
  • Solder mask & legend: solder-mask printing, exposure, develop; silk-screen legend
  • Surface finish & out: ENIG / immersion tin / OSP, routing, V-CUT, e-test, FQC, packing
