Mobile phone high-low temperature test solution

The mobile phone is one of the electronic products that people use frequently in daily life. The mobile phone will encounter various ambient temperatures during use. Therefore, high-low temperature tests are required to ensure that the mobile phone can work normally at different temperatures. The high-low Temperature Test Chamber can simulate different temperature environments to test the working performance and reliability of mobile phones at high-low temperatures.

High temperature test: Put the mobile phone in a high temperature environment, usually 60°C to 85°C, for several hours to several days. At this time, the electronic components and batteries inside the mobile phone will be affected by high temperature, and whether they can withstand the influence of high temperature environment is tested to evaluate its reliability and performance in high temperature environment.

Low temperature test: Put the mobile phone in a low temperature environment, usually -20°C to -40°C, for several hours to several days. At this time, the electronic components and batteries inside the mobile phone will be affected by low temperature, and whether they can withstand the impact of low temperature environment is tested to evaluate its reliability and performance in low temperature environment.

Temperature cycle test: Place the mobile phone alternately in high-low temperature environments to test its stability and tolerance under different temperature changes, so as to simulate the temperature changes in the actual use environment.

These tests can help mobile phone manufacturers and users to evaluate the performance and reliability of mobile phones to ensure that they can work stably and for a long time in actual use.

Application of high-low Temperature Test Chamber in mobile phone high-low temperature resistance test and its test steps:

• Prepare samples: select a mobile phone as a test sample, and determine the placement method according to the size and weight of the mobile phone.
  

• Set temperature: Set the temperature range and heating rate of the high-low Temperature Test Chamber according to the test requirements.

• Place the sample: Put the mobile phone into the high-low Temperature Test Chamber and make sure it is placed firmly.

• Carry out tests: According to the set temperature range and heating rate, conduct high temperature and low temperature tests, and record the working status and performance of the mobile phone at different temperatures.

• Analysis results: Through test data and analysis, evaluate the working performance and reliability of mobile phones in different temperature environments, and provide reference and guidance for production and use.
