How to test mobile phone shells and other electronic products under high and low temperature test chambers?

 

electronic products

 

Everyone has a smart phone, and the lack of a smart phone has a great impact on work and life. All parties have begun to electronically, such as buying bicycle bags in Taobao, alu glass tape, waterproof hats, watch, 2 pc pajama set etc. all need to be paid with Alipay.

 

Mobile phones, cameras, android tablets, power bank and other digital electronic products, general manufacturers will purchase high and low temperature test chamber environmental test equipment, yes The product is subjected to high and low temperature tests, such as testing mobile phone batteries, whether there will be high temperature explosions at ﹢100℃.

 

The high and low temperature test box solves our fears, so that what consumers buy can be used safely in different environments. Therefore, the high and low temperature test box is inseparable in our daily life, whether it is in life or in production. This device is indispensable in all.

 

As one of the indispensable accessories to protect the mobile phone, how about the temperature tolerance of the mobile phone film? Let's take a closer look. Take our high and low temperature test box as an example, set the temperature to the high temperature conditions we may encounter in the natural environment.

1. You should understand the test subject

 

2. High temperature test is carried out

Since the content of the test is to detect the high temperature resistance of the mobile phone's tempered film, the daily temperature does not have any substantive significance. Even if the summer temperature is higher, the impact on the mobile phone's tempered film will not be great. Today, we will directly simulate the high temperature conditions that mobile phones may encounter in summer. First, start with a high temperature of 70°C and observe whether the tempered film has changed.

 

70℃ high temperature test

 

Step 1

First of all, please take out our high and low temperature test box, and put the test sample into the box.

 

Step 2

Start the high and low temperature test box on the tall, set the temperature to 70°C, and run for 1 hour (note that the constant temperature is 1 hour at 70°C).

 

Step 3

Observe the test sample after the time has elapsed, and observe its shape, viscosity, and blistering.

 

3. Extremely high temperature test carried out

The tempered film is still intact at a high temperature of 70°C, so it is tested from a temperature of 80-90-100°C. Of course, there is still no change, and the viscosity and shape are not affected, so just do it to the extreme If it is 150℃, then some people will ask, under what conditions will mobile phones encounter a high temperature of 150℃? In fact, it can be concluded now that high temperature does not have much influence on the shape of the tempered film. What we need to test now is whether the extreme temperature can melt this hard tempered film.

 

150℃ high temperature test

Step 1

Put the tempered film on the sample rack of the high and low temperature test box on the tall.

 

Step 2

Restart the high and low temperature test box on the tall, set the temperature to 150°C, and the running time is 1 hour (note that the constant temperature is 1 hour under the condition of 150°C).

 

Step 3

Observe the test sample after the time has elapsed, and observe its shape, viscosity, and blistering. After taking out the tempered film from the high and low temperature test box, it was placed in the external environment for about ten minutes before it gradually cooled down. The surprise is that the tempered film did not change except for heating, that is, even at a high temperature of 150℃. , Is still intact as before, does not foam, does not deform, and can be used. This quality is comparable to Haida’s test box~

 

4. Low temperature test

After the high temperature test is performed to test the high temperature resistance of the tempered film, it is time to check the low temperature conditions. The editor knows that minus one to twenty degrees has little effect on the tempered film, so let’s just make a lower temperature and let’s take a look. Will the tempered film be affected?

 

-45℃ low temperature test

Step 1

 

Put the tempered film on the sample rack of the high and low temperature test box on the tall.

 

Step 2

Start the high and low temperature test box again on the tall, set the temperature to -45℃, and the running time is 1 hour (note that the constant temperature is 1 hour under the condition of -45℃).

 

Step 3

Observe the test sample after the time has elapsed, and observe its shape, viscosity, and blistering. It can be seen that thin crystals have formed at the moment the door is opened due to the low temperature, but! Our tempered film is still intact, unaffected by temperature at all,

 

5. Test summary

After 24 hours of repeated temperature tests, the tempered film of this iPhone is still unaffected, and the question in the title has an answer. Yes, it is really safe to put the tempered film on iPhone! The editor is very pleased that I have collected this good-quality tempered film, and now I am missing an iPhone~

 

As one of the professional test chamber suppliers, we suggest that it’s better try to test electronic products by high and low temperature test chambers.
