What Reliability Tests Do ValueHD Corporation ODM Products Undergo?

Reliability testing is the final “stress test” before mass production—pushing products into extreme environments and operating conditions to see whether problems emerge.

For ODM customers, this directly addresses a core question: How long will your product last in customers’ hands? How high will the return rate be?

As an A-share listed company (stock code: 301318) with 20 years of deep expertise in the audio and video field, ValueHD Corporation subjects ODM products to a complete reliability testing system before shipment, covering environmental, mechanical, and long-term stability dimensions. Specific tests include:

I. Environmental Reliability Testing: Can It Withstand Extreme Climates?

Products are sold nationwide and even globally—winter in Northeast China, summer in the South, humid coastal areas—various climatic environments may be encountered. Environmental reliability testing simulates these extreme scenarios.

1. High-Temperature Burn-In Testing

Products are placed in high-temperature environments and run continuously for extended periods to test stability and component tolerance under high-temperature conditions. High temperature is one of the biggest “killers” of electronic components—many products perform fine at room temperature but crash, reboot, or degrade in summer, often because burn-in testing was insufficient.

2. Humidity Testing

Simulates high-humidity environments to test operational stability and corrosion resistance under damp conditions. During the plum rain season in the South or in coastal areas with high humidity, PCBs without adequate moisture protection can easily suffer short circuits or mold.

3. High-Low Temperature Cycling Testing

Repeatedly switches between high and low temperatures to simulate scenarios with drastic temperature changes. Rapid temperature shifts cause thermal expansion and contraction, testing solder joints, structural parts, and seals. Many products pass high-temperature or low-temperature testing individually but fail when alternating between hot and cold—high-low temperature cycling testing is specifically designed to screen for such issues.

II. Mechanical Reliability Testing: Can It Withstand Transport and Use?

From the factory to the customer, products undergo transport, handling, installation, and daily use—every step involves mechanical stress. Mechanical reliability testing simulates these physical impacts.

4. Vibration Testing

Simulates the vibration environment during transport, testing structural integrity and functional stability under sustained vibration. During road transport and express logistics, products may shake for days—loosened screws, loose connectors, and displaced internal parts are all issues vibration testing aims to detect in advance.

5. Drop Testing

Simulates accidental drops during handling or use, with free falls from specified heights to test structural impact resistance and functional integrity. Small desktop devices in particular face a considerable risk of being knocked over or dropped, so structural strength must meet standards.

6. Interface Insertion/Extraction Life Testing

Interfaces are the most frequently used and most failure-prone components on a product. USB, HDMI, power connectors… with daily plugging and unplugging, will they loosen over time? Will contact become poor? Insertion/extraction life testing involves thousands to tens of thousands of repeated plug cycles to verify interface durability and ensure reliability throughout the product lifecycle.

III. Long-Term Reliability Testing: Will Problems Emerge Over Time?

Some issues cannot be seen in the short term and only surface after prolonged continuous operation—early component failure, software memory leaks, cumulative thermal effects…

7. Long-Term Stability Testing

Products run continuously for extended periods (typically hundreds of hours or longer) at full load, simulating long-term customer usage while monitoring whether performance metrics remain stable and whether abnormal crashes, disconnections, or performance degradation occur.

This test is the most time-consuming, but it best reflects true product quality—short-term performance is not enough; long-term stability is what truly matters.

The Value of Reliability Testing Ultimately Lies in Reducing Risk for Customers
