0.4mm-3.2mm Board Double Sided PCB Fabrication Service High Density

Double-sided PCBs provide higher circuit density than single-sided boards, enabling more complex designs in a compact footprint—ideal for power supplies, automotive electronics, industrial controls, and communication devices. Studio Electronics offers Double-Sided PCB Fabrication with high-density capability and rigorous quality control. As a leading provider of PCB assembly in China, we fabricate double-sided boards with plated through-holes, fine traces, and precise registration—ensuring reliable electrical connections between layers. Our complete turnkey service covers PCB fabrication, component sourcing, SMT assembly, testing, and shipping.

Stage 1: Material Procurement
We source FR4, CEM-3, High-TG, Halogen-Free, and metal base materials from qualified suppliers. Every material shipment undergoes incoming inspection.

Stage 2: Circuit Pattern Formation
Circuit patterns are produced on both sides through photo imaging and etching. Precise layer-to-layer registration is maintained through advanced imaging equipment.

Stage 3: Drilling & Plating
Precision drilling creates through-holes for vias and component leads. Plating processes ensure reliable electrical connections between top and bottom layers. Plating thickness is verified through cross-section analysis.

Stage 4: Surface Finishing
Multiple surface finish options: ENIG (for fine-pitch components), HASL (for solderability), OSP (cost-effective protection), Immersion Silver (high-frequency applications), Immersion Tin (flat surfaces), and Gold Plating.

Stage 5: Electrical Testing
Every board undergoes 100% electrical testing—flying probe or fixture-based. For low volume PCB assembly, flying probe eliminates fixture costs.

Stage 6: Final Inspection & Shipping
AOI inspection for trace integrity; dimensional verification; visual inspection; professional packaging.
