PCB Testing Services
for Electronic Products
Product-level functional testing, assembly inspection, and shipment-ready verification for assembled electronic products.
Verify key product functions after assembly
Check PCBA, wiring, buttons, displays, sensors, and connectors
Follow customer-defined testing points and acceptance criteria
What Our Functional Testing Covers
Testing points are arranged according to product function, assembly structure, usage scenario, and customer-defined acceptance criteria.
Product-Level
Functional Testing
We verify assembled electronic products after PCBA installation, wiring connection, enclosure fitting, and final assembly.
Power & Basic Check
- Power-on response
- Indicator or LED status
- Charging or connection behavior
Interface & Control Testing
- Button and switch operation
- Display or touch response
- Control interface behavior
Sensor, Signal & Audio Check
- Sensor feedback
- Signal response
- Speaker, buzzer, or sound output
Assembly-Related Function Review
- Cable and connector condition
- PCBA installation status
- Housing fit and appearance
After-Assembly Problems We Help Catch
Some issues only appear after the PCBA, enclosure, cables, buttons, sensors, and display are assembled into the final product. Functional testing helps identify these problems before packaging and shipment.
Assembled Product
Functional Check
Before final packaging
and shipment
Function Response
Product powers on but does not respond correctly.
Connector Condition
Connector is not fully seated or locked.
Display Alignment
Display, LED, or sensor window is not aligned.
Button Operation
Button or switch travel is blocked by the housing.
Cable Routing
Cable is pinched or pulled during final assembly.
Port Position
Charging port or interface does not match the opening.
By checking the complete assembled product, we help reduce functional risks before final packaging and delivery.

Detailed Testing Services
Automated Optical Inspection (AOI)
High-resolution imaging to detect solder joints, component alignment, and surface defects.
- Principle: Optical vision compares captured images with golden reference.
- Applications: Fine-pitch, HDI boards, BGA/QFN alignment.
- Capabilities: Resolution ≤ 5–10 µm; false-call rate < 0.1%.
- Client Benefits: Reduce rework & defects; faster feedback to process.
In-Circuit Testing (ICT)
Electrical verification of nets, values, orientation, and shorts/opens before final assembly.
- Principle: Probe matrix measures component values and continuity.
- Applications: Mass production with stable test coverage.
- Capabilities: Up to 2048 nodes; boundary-scan optional.
- Client Benefits: Catches early failures; stable quality at scale.
Functional Verification
Simulates real operating conditions to validate firmware, interfaces, and performance.
- Principle: Power-on, I/O simulation, interface loopback & load tests.
- Applications: MCU/FPGA boards, IoT devices, communication modules.
- Capabilities: USB/UART/CAN/Ethernet; programmable loads 0–10 A.
- Client Benefits: Ensures user-level functionality before shipment.
Environmental & Reliability Tests
Stress tests for durability under temperature, humidity, and vibration cycles.
- Principle: Accelerated aging by thermal/humidity or mechanical stress.
- Applications: Automotive, outdoor, industrial control electronics.
- Capabilities: −40 °C ~ +85 °C; 10–95 %RH; vibration per spec.
- Client Benefits: Predict field reliability; lower warranty risk.
