Overview

Electrical integrity is the most critical quality metric for PCBs—a single open circuit or short can render an entire board useless. Studio Electronics offers Quality PCB Fabrication with 100% electrical testing on every board. As a quality-focused provider of PCB assembly in China, we combine advanced fabrication capability with comprehensive electrical testing—flying probe or fixture-based—to verify continuity and isolation on every board. Our complete turnkey service covers PCB fabrication, component sourcing, SMT assembly, testing, and shipping.

100% Electrical Testing – Our Commitment

The Fabrication Process with 100% Testing

Stage 1: Material Procurement & Incoming Inspection
We source all materials from qualified suppliers. Incoming inspection verifies material certifications, dimensional compliance, and quality documentation.

Stage 2: Imaging & Etching
Circuit patterns are produced through photo imaging and controlled etching. AOI inspection verifies trace integrity and detects any defects.

Stage 3: Lamination
Layers are laminated under controlled temperature and pressure. X-Ray inspection verifies layer alignment and registration.

Stage 4: Drilling & Plating
Precision drilling creates vias and through-holes. Plating processes ensure reliable electrical connections. Plating thickness is verified through cross-section analysis.

Stage 5: Surface Finishing
Surface finishes applied—ENIG, HASL, OSP, Immersion Silver, Immersion Tin, Gold Plating—with thickness verification.

Stage 6: 100% Electrical Testing
Every board undergoes comprehensive electrical testing:

• Continuity Testing – Verifies all nets are connected

• Isolation Testing – Verifies no shorts between nets

• Impedance Testing – Verifies controlled impedance (when specified)

• Flying Probe Testing – Used for low volume PCB assembly; eliminates fixture costs

• Fixture-Based Testing – Used for volume orders; rapid testing

Stage 7: Final Inspection & Shipping
Comprehensive AOI inspection; dimensional verification; visual inspection; professional packaging.

Substrate Materials & Surface Finishes

Why 100% Electrical Testing Matters

• Zero Defects – Every board verified; no opens or shorts escape

• Reliability – Electrical integrity confirmed before assembly

• Traceability – Test results documented per board

• Cost Efficiency – Catch defects early; avoid costly assembly rework

• Regulatory Support – Documented testing supports regulatory submissions

• Low Volume Support – Flying probe testing for low volume PCB assembly

Studio delivers Quality PCB Fabrication with 100% electrical testing—every board verified, every defect eliminated.
