100% Incoming Material Inspection

Quality starts with qualified materials.

All incoming components, PCBs, electronic parts, plastic housings, batteries, cables, and packaging materials undergo strict inspection before entering production.

Depending on project requirements, we perform:

• Visual inspection
• Dimension verification
• Functional testing
• Supplier compliance verification
• Material consistency checks

For critical components, we conduct 100% inspection to ensure conformity with specifications.

Monitoring Every Manufacturing Step

During production, our IPQC team continuously monitors manufacturing quality and process stability.

Inspection checkpoints are established throughout the assembly process to verify:

• Assembly accuracy
• Soldering quality
• Process consistency
• Functional performance
• Work instruction compliance

This proactive approach helps identify and eliminate potential issues before they affect finished products.

100% Functional and Cosmetic Inspection

At the FQC stage, every assembled product undergoes comprehensive inspection before packaging.

Inspection items typically include:

• Product appearance
• Functional testing
• Button operation
• Charging performance
• Sensor verification
• Camera image quality
• Waterproof verification (where applicable)

Only products that pass all inspection requirements proceed to packaging.

Final Verification Before Shipment

Before shipment, our OQC team performs another round of inspections to verify:

• Product functionality
• Cosmetic condition
• Packaging quality
• Label accuracy
• Shipment compliance

This final verification ensures only qualified products leave our facility.

Before mass production and during product validation, we perform various reliability tests according to project requirements, including:

• Waterproof testing
• Airtightness testing
• Drop testing
• Temperature testing
• Aging testing
• Battery charging and discharging verification
• Environmental testing
• Noise Level testing

These tests help verify long-term durability and product reliability under real-world conditions.

Quality management does not end when products leave our factory.

If a customer reports a quality concern, our quality team immediately initiates a structured investigation process.

Our corrective action procedure includes:

Problem Analysis

• Data collection
• Failure verification
• Production record review

Root Cause Investigation

• Using structured analysis methods to identify the actual source of the issue.

Corrective Actions

• Process improvements
• Supplier corrective actions
• Engineering changes
• Additional inspection controls

Preventive Actions

Implementation of preventive measures to reduce the likelihood of recurrence.

This closed-loop quality management process allows us to continuously improve product reliability and customer satisfaction.
