7)． Reliability testing
5.1
Free fall
Drop the product freely onto the cement floor from 1m height , 6 sides / 1 time
for each side. Check whether each side is cracked and loose in the experiment.
Then test the electrical function, buttons, lights, shaking the sound inside the
listening machine, and so on.
If no parts
or structural
parts fall
off, it is OK
5.2
vibration
test
According to the characteristics of our vibration tester, set the frequency of
100Hz, shake for 10 minutes, and observe whether the product is cracked and
loose after the experiment. Check the electrical function again. Button.
Indicator light. Sound. And so on whether normal.
If no parts
or structural
parts fall
off, it is OK
5.3
USB plug
test
Use the charging cable, simulate the normal use of plug and unplug action,
plug and unplug 1000 times, plug and unplug speed of 10 ~ 20 times/minute,
after the test to confirm whether the port can be normal plug and unplug
(after the test socket is allowed to have slight appearance damage), after the
test function test whether there is poor contact.
OK
5.4
high low
temperatu
re cycling
Place the product in a temperature-controlled box with a temperature of
20 ° C ± 5 ° C as follows A) Place the sample in an experimental
chamber with a temperature of 40 ℃ ± 2 ℃ for 2 hours; B) Lower the
temperature of the chamber to -10 ℃ ± 2 ℃ and keep it for 4 hours; C)
Temperature conversion time is less than 30 minutes; D) Repeat steps A) to b)
for a total of 5 times; Detection products, appearance and structure without
bad phenomenon, no fire and fracture test electrical function, buttons,
indicators, sound, and other no bad phenomenon.
OK
6.1
salt spray test
For hardware, salt spray test should be carried out before incoming
material is put on line. 5% NaCl solution,PH value between 6.5 and 7.3,
under 35 ℃ environment by the salt spray machine 1.4± 0.2kg/CMS 2
air pressure automatic spray for 12 hours. No corrosion occurs.
OK
6.2
Keystroke
fatigue test
Simulate the action of pressing the key in normal use. Press the key
repeatedly 3000 times with 250g force on the instrument platform,
and confirm whether the key can be used normally after the test.
OK
6.5
Charge test
Take Iphone, Samsung, HUAWEI, Xiaomi, OPPO and other mobile
phones as the test reference object, respectively play music while
charging whether it is normal.
6.6
aging test
Turn the lights to maximum brightness and repeat this cycle 3 times.
Charge and put for 12 hours, and then test the electrical function to see if
it is normal 。
OK
