Station 01
IQC (Incoming Quality Control)
Pre-assembly inspection of display panels, sensors, battery cells, housing frames, and flexible silicone/metal straps.
Rigorous QA Framework
Engineering Reliability into Every Smart Wearable
At Dongguan Brainox Technology Co., Ltd., we understand that global consumer electronics brands, health-tech companies, and telecommunications distributors demand zero compromise on product durability and sensor accuracy. Our dedicated in-house reliability laboratory validates every component and finished wearable under extreme operational and environmental conditions.
From initial component screening through IQC to mass production aging, air-tight waterproof validation, and simulated freight vibration tests, our systematic 19-step testing framework ensures all exported devices comply with CE, RoHS, and FCC market expectations.
Comprehensive Defect Prevention
Strict IQC component screening prevents defective displays, batteries, or PCBAs from entering the production line.
Extreme Environment Stress Testing
Programmable climatic chambers, drop drums, and salt spray chambers ensure robust performance in harsh climates.
Four-Tier Quality Gate
Standardized Quality Assurance Workflow
1. IQC Inspection
100% incoming testing of battery capacity, display resolution, touch responsiveness, and waterproof gasket integrity.
2. In-Process Validation
RF power calibration, Bluetooth pairing latency, micro-air pump pressure calibration, and electrode continuity checks.
3. Environmental Stress
Full-cycle aging, high/low thermal shock, salt-spray anti-corrosion, and structural drop resistance simulations.
4. OQC & Freight Check
100% finished cosmetic review, carton vibration testing, and lithium battery air-freight compliance checks.
