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
| Test Type | Method | What We Verify |
|---|---|---|
| Continuity Testing | Flying probe or fixture-based | All nets are connected; no opens |
| Isolation Testing | Flying probe or fixture-based | No shorts between nets; proper isolation |
| Impedance Testing | TDR (Time Domain Reflectometry) | Controlled impedance within tolerance |
| High-Potential Testing | Hi-Pot (optional) | Dielectric strength; no breakdown |
| Low-Volume Testing | Flying probe (no fixture required) | Cost-effective verification for low volume PCB assembly |
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
| Board Type | Substrate Materials | Surface Finishes |
|---|---|---|
| Single-Sided | FR4, CEM-1, Aluminum, Ceramic | HASL, OSP, ENIG, Immersion Silver |
| Double-Sided | FR4, CEM-3, High-TG, Halogen-Free | HASL, ENIG, OSP, Immersion Tin |
| Multi-Layer | FR4, High-TG, Rogers, Halogen-Free | ENIG, Immersion Silver, Gold Plating |
| Flexible | Polyimide, Polyester | ENIG, Immersion Silver, OSP |
| Rigid-Flex | FR4 + Polyimide | ENIG, OSP, Gold Plating |
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.
