Common reliability testing items for electronic products

electronic productReliability testing is an important step in ensuring the long-term stable operation of products under predetermined conditions. The following are common reliability testing items:

1. Environmental testing

· Temperature cycling testCycle between high and low temperatures to evaluate the performance changes of components at extreme temperatures.

· Humidity testTest in high humidity environment to check the product's tolerance to moisture.

· Salt spray testTest in a salt spray environment to evaluate the product's resistance to corrosion.

2. Mechanical testing

· Vibration testingSimulate vibrations during transportation and use to evaluate the structural integrity of the product.

· Impact testingEvaluate the product's ability to withstand impact.

· Drop Test Test the performance changes of the product after falling from a certain height.

3. Electrical testing

· Overload test Apply voltage and current beyond the normal operating range and check the protective performance of the product.

· Short circuit testSimulate a short circuit situation and evaluate the safety of the product.

· Electromagnetic compatibility（EMC testingTest the performance of the product under electromagnetic interference.

4. Life testing

· Accelerated aging testAccelerate aging under extreme conditions such as high temperature, high humidity, and overload, and evaluate the service life of the product.

· Cycle life testPerform charge and discharge cycles on rechargeable batteries and evaluate their lifespan.

5. functional testing

· performance testing Verify whether the product functions properly under various conditions.

· Stability testingMonitor the performance changes of the product during long-term operation.

6. Security testing

· Electrical safety testingCheck insulation, leakage current, etc. to ensure the safety of the product during use.

· Hot testingEvaluate the heating situation of the product during operation to ensure that it does not exceed the safety limit.

7. Material testing

· Welding strength testTest the strength of solder joints to ensure welding quality.

· Temperature resistance testEvaluate the performance changes of materials in high-temperature environments.

8. reliability index

· Inefficiency（Failure Rate）The probability of a malfunction occurring within a certain period of time.

· Mean time between failures（MTBF)The average time between each malfunction.

· Average repair time（MTTR)The average time required to repair faults.

Through these reliability tests, the performance and durability of electronic products in actual use can be effectively evaluated, ensuring product quality and customer satisfaction.
