Quality Assurance & Control System

At SENDTECH, quality is the foundation of our product reliability and long-term customer trust. We have established a comprehensive Quality Assurance and Quality Control (QA/QC) system covering research & development, material sourcing, manufacturing, and final inspection.

1. R&D Quality Management

Our R&D process strictly complies with applicable national standards, industrial standards, and relevant military-grade specifications.

We implement standardized management procedures throughout product development, including:

• Design review and validation

• Prototype verification

• System-level testing and simulation

• Functional and environmental experiments

Through multi-stage verification and performance validation, we ensure high reliability, structural stability, and optimized performance before mass production.

2. Incoming Material Control

We maintain long-term strategic partnerships with internationally recognized component suppliers to ensure stable and high-quality sourcing.

All incoming materials undergo strict inspection procedures, including:

• Component specification verification

• Electrical parameter testing

• Appearance and packaging inspection

• Random sampling reliability checks

Only qualified materials are approved for production.

3. Manufacturing Process Quality

Our production line is equipped with advanced SMT (Surface Mount Technology) equipment and precision testing instruments.

Quality control measures include:

• Strict process control and documentation

• Real-time production monitoring

• In-process inspection at critical stages

• Reliability sampling during production

Before shipment, every product must pass:

• Functional testing

• Performance calibration

• Output inspection

• Final quality verification

No product leaves the factory without complete inspection approval.

4. Continuous Quality Improvement

Quality improvement is an ongoing process at SENDTECH.

We regularly conduct:

• Internal quality review meetings

• Process optimization initiatives

• Technical improvement projects

• Employee suggestion programs

• Cross-department quality team activities

Through continuous improvement practices, we enhance product reliability, manufacturing efficiency, and customer satisfaction.

Reliability Testing

To ensure that our MESH communication devices operate reliably in harsh environments, we conduct comprehensive environmental and mechanical reliability tests.

Environmental Testing

High Temperature Test

Products are exposed to elevated temperatures under specified humidity and time cycles to verify electrical performance, mechanical integrity, and appearance stability.

Low Temperature Test

Products are tested under low-temperature storage and operating conditions to ensure no structural damage or performance degradation occurs.

Thermal Shock Test

Products undergo repeated rapid temperature transitions to validate resistance to sudden environmental temperature changes.

Rain Test

Simulates water exposure caused by condensation or leakage to ensure normal operation under wet conditions.

Hot and Humid Test

Products are subjected to cyclic temperature and humidity variations to evaluate resistance to moisture and damp heat.

Salt Spray Test

Validates corrosion resistance under salt fog and harsh atmospheric conditions.

Sand and Dust Test

Under controlled temperature, humidity, airflow speed, and dust concentration, products are tested to verify resistance to dry sand and dust exposure.

Mechanical Reliability Testing

Vibration Test

Products are subjected to fixed-frequency and random high-intensity vibration tests to simulate transportation and operational conditions, ensuring structural stability and performance reliability.

Drop Test

Products and packaging are tested through repeated free-fall experiments at designated heights and angles to verify mechanical strength and shock resistance.

Shock (Crash) Test

Simulates mechanical impact conditions to validate electrical performance stability and structural durability under sudden shocks.

Solar Radiation Test

Products are exposed to controlled sunlight intensity, temperature, and duration cycles to ensure long-term resistance to UV and solar radiation.

Commitment to Reliability

Through rigorous testing and strict quality management, SENDTECH ensures that every MESH network radio system delivers:

• Stable performance
