Quality PCB Fabrication – 100% Testing Electrical
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 |
