How It's Made

Manufacturing Process

Advanced rigid PCB fabrication with strict quality control at every stage

Material Preparation

Rigid laminates (FR4/Rogers) are cut to production panel size. We verify surface quality and thickness consistency before inner layer processing.

FR-4LaminationPanelization

High-Precision Drilling

CNC mechanical drilling for through-holes and CO2/UV laser drilling for HDI micro-vias. Accuracy maintained within ±25 µm.

CNC DrillLaser Vias±25µm

Pattern & Plating

Advanced electroplating for hole wall metallization followed by LDI (Laser Direct Imaging) for ultra-fine circuit pattern transfer.

LDI ImagingCopper PlatingFine-Line

Surface Finishing

Application of ENIG, HASL, OSP or Immersion Silver to protect copper and ensure superior solderability during PCB assembly.
