Bench Testing Protocol
Load simulation, communication verification, and functional validation under real-world operating conditions
Power-on test: Verify voltage rails, current draw, and startup sequence
Load simulation: Test under simulated operating conditions
Final QC Gates
Visual inspection, functional validation, and 24-hour burn-in test to ensure long-term reliability
Visual inspection: Solder joints, component placement, board cleanliness
Functional validation: Re-test all control functions and communication
Component-Level Expertise You Can Trust
Every controller goes through our rigorous 5-step process with bench testing, load simulation, and 24-hour burn-in validation. We don't just fix symptoms—we diagnose root causes and restore OEM performance.
3-Point QA Gates
Every controller passes through rigorous quality checkpoints before shipment
Visual Inspection
Solder joint quality and integrity
Component placement and orientation
Board cleanliness and contamination
Electrical Testing
Power supply voltage rails (±5%)
Current draw under load conditions
Ground continuity and isolation
Functional Validation
CAN bus communication verification
Control output signal validation
Sensor input response testing
✓ Quality Assured Before Shipment
Our 3-point QA process ensures every controller meets OEM specifications. We don't ship until it passes visual inspection, electrical testing, and functional validation—including a 24-hour burn-in test.
