Guangdong Deci Technology Co., Ltd.: Building Excellence in Piezoelectric Ceramics through Core Reliability Testing

As a leading R&D and manufacturing enterprise of piezoelectric ceramic materials in China, Guangdong Deci Technology Co., Ltd. has always regarded product reliability as the lifeline of its operations. Piezoelectric ceramics, serving as core components in sensors, transducers, and precision actuators, directly impact the lifespan and safety of end-use equipment through their performance stability. To this end, we have established a comprehensive reliability testing system spanning the entire production chain, ensuring every product delivers exceptional performance under complex operating conditions through rigorous testing protocols.

I. Why Prioritize Reliability Testing for Piezoelectric Ceramics?

The reliability of piezoelectric ceramics hinges on multidimensional factors including material stability, structural integrity, electrical performance, and environmental adaptability. In high-end applications such as medical devices, industrial automation, automotive electronics, and aerospace, components may face extreme conditions like high temperatures, vibrations, humidity, and prolonged loads. Insufficient validation could lead to signal distortion, efficiency degradation, or functional failure. Through scientific testing frameworks, Guangdong Deci proactively identifies risks, delivering "zero-defect" product assurance to clients.

II. Core Dimensions of Reliability Testing

Aligned with international standards (e.g., IEC, ISO) and industry requirements, we have developed the following testing modules:

Environmental Adaptability Testing

• Temperature Cycling Tests: Simulate extreme thermal shocks (-40°C to 150°C) to validate material thermal expansion compatibility and structural stability.

• Damp Heat Aging Tests: Conduct 1,000-hour continuous testing at 85°C/85% RH to evaluate ceramic insulation properties and electrode corrosion resistance.

• Salt Spray Testing: Assess protective efficacy of encapsulation processes for marine or industrial corrosive environments.

Mechanical Reliability Testing

• Vibration & Shock Testing: Simulate mechanical stress during transportation, installation, and usage via random vibrations (5–2000Hz) and multi-axis shocks (50g acceleration) to ensure crack- and delamination-free structures.

• Fatigue Life Testing: Apply over 1 million cyclic loads to piezoelectric ceramics, monitoring displacement output attenuation rates to guarantee long-term actuation precision.

Electrical Performance Stability Testing

• High-Voltage Breakdown Testing: Apply 2–3 times the rated voltage to verify dielectric strength and insulation layer reliability.

• Impedance-Frequency Analysis: Use precision LCR meters to ensure consistency in resonant frequency and electromechanical coupling coefficients for accurate signal response.

• Load Aging Tests: Operate continuously for 500 hours under rated voltage while monitoring dielectric loss and piezoelectric constant (d33) drift rates.

Lifetime Prediction & Failure Analysis

• Accelerated Life Testing (ALT): Apply Arrhenius model-based high-temperature/high-voltage aging to estimate MTBF (Mean Time Between Failures) under normal conditions.

• Microstructural Analysis: Utilize SEM (Scanning Electron Microscopy) and XRD (X-ray Diffraction) to analyze grain boundaries, porosity, and defects, optimizing sintering processes.

III. Intelligent Testing Platforms & Quality Control Systems

Guangdong Deci has invested in an industry-leading reliability laboratory equipped with multi-channel data acquisition systems, thermal shock chambers, and electromagnetic vibration testers, enabling automated testing and data visualization. Our closed-loop "Design-Production-Testing" management ensures excellence:

• DFR (Design for Reliability): Integrate reliability simulation models during material formulation and electrode structure design.

• SPC (Statistical Process Control): Monitor critical parameters like sintering temperature and poling voltage in real time for batch consistency.

• 100% Inspection & Sampling Retests: Perform full inspections on key parameters before shipment, supplemented by periodic destructive testing.
