With so many major players in the tablet PC market…
How can you compete?
The answer?
By making sure that you’re manufacturing a quality product!
…and how do you do that?
By carrying out these Top 5 Tests for Tablet PCs
during your next product inspection!
Touch screens are a vital component of tablet PCs.
Any quality factory that manufactures tablet PCs should be equipped with a testing machine.
Use a testing machine to verify responsiveness and longevity of the touch screen function.
Use a testing machine to verify responsiveness and longevity of the touch screen function.
A tablet PC should be tested for at least 30,000 cycles to simulate lifetime usage.
Battery capacity and charge/discharge should be tested.
Test battery lifespan by:
Test battery lifespan by:
1. Fully charging the tablet PC
Test battery lifespan by:
2. Playing video at maximum volume until the battery expires.
1. Fully charging the tablet PC
As with a screen testing machine, a well-equipped factory should be able to provide a battery charger.
To test battery charge/discharge:
To test battery charge/discharge:1. Remove the battery protection board
To test battery charge/discharge:
2. Charge and discharge the battery 20 cycles1. Remove the battery protection board

2. Charge and discharge the battery 20 cycles1. Remove the battery protection board
3. Compare the actual capacity found to the rated capacity
If battery capacity tested is less than the rated capacity, the tablet fails this test.
If battery capacity tested is less than the rated capacity, the tablet fails this test.
Screen separation is a common problem seen with lower-quality tablet PCs.
Tablets should be tested for screen adhesion to ensure that screens won’t easily separate from the tablet during normal
use.
To test screen adhesion:
To test screen adhesion:1. Apply 3M tape to the tablet screen
To test screen adhesion:
2. Tear the 3M tape off the screen1. Apply 3M tape to the tablet screen

2. Tear the 3M tape off the screen1. Apply 3M tape to the tablet screen
3. Check that the screen is still firmly in place
Vibration testing simulates forces products are subjected to during transportation and shipping.
An important part of product inspection for tablets, vibration testing involves the use of a vibration table.

The International Safe Transit Association (ISTA) provides procedures for vibration and related testing for consumer
products.
To conduct vibration testing for tablet PCs:
To conduct vibration testing for tablet PCs:1. Use units that have already passed AQL defect inspection
To conduct vibration testing for tablet PCs:
2. Place units in their retail packaging on the vibration table running at 200RPM for 2 hours
1. Use units that have already passed AQL defect inspection
To conduct vibration testing for tablet PCs:
2. Place units in their retail packaging on the vibration table running at 200RPM for 2 hours
1. Use units that have already passed AQL defect inspection
3. Check the units for functionality and performance
If the units tested maintain full functionality and performance, the tablets have passed vibration testing.
Environmental testing for products simulates how extreme conditions can affect product functions.
In the case of tablet PCs, it’s important to check functionality after prolonged exposure to high temperature and humidity.
An environmental chamber, or climate chamber, is an enclosure used to carry out such testing.
A number of standards for environmental chambers exist, including:
A number of standards for environmental chambers exist, including:• International Organization for Standardization (ISO)
A number of standards for environmental chambers exist, including:• International Organization for Standardization (ISO)• American Society for Testing and Materials (ASTM)

(IEST)
To carry out environmental testing for tablet PCs:
To carry out environmental testing for tablet PCs:1. Keep the units in an environmental chamber with a temperature
of 55 C +/- 2 C and a humidity of 85% for 8 hours

If the units tested maintain full functionality and performance, the tablets have passed environmental testing.
If the units tested maintain full functionality and performance, the tablets have passed environmental testing.
That’s it!
Now you’ve learned how to conduct five top tests for tablet PCs.
So put them to practice!
Leave the competition behind.
And make sure your next order of tablet PCs isn’t DOA.
