7. With so many major players in the tablet PC market…

8. How can you compete?

9. By making sure that you’re manufacturing a
quality product!

10. …and how do you do that?

11. By carrying out these Top 5 Tests for
Tablet PCs
during your next product inspection!

13. Touch screens are a vital component of tablet PCs.

14. Any quality factory that manufactures tablet PCs
should be equipped with a testing machine.

15. Use a testing machine to verify responsiveness and
longevity of the touch screen function.

16. Use a testing machine to verify responsiveness and
longevity of the touch screen function.

17. A tablet PC should be tested for at least 30,000 cycles to
simulate lifetime usage.

19. Battery capacity and charge/discharge should be
tested.

20. Test battery lifespan by:

21. Test battery lifespan by:
1. Fully charging the tablet PC

22. Test battery lifespan by:
2. Playing video at maximum volume until the battery exp
1. Fully charging the tablet PC

23. As with a screen testing machine, a well-equipped
factory should be able to provide a battery charger.

24. To test battery charge/discharge:

25. To test battery charge/discharge:
1. Remove the battery protection board

26. To test battery charge/discharge:
2. Charge and discharge the battery 20 cycles
1. Remove the battery protection board

27. To test battery charge/discharge:
2. Charge and discharge the battery 20 cycles
1. Remove the battery protection board
3. Compare the actual capacity found to the rated capacity

28. If battery capacity tested is less than the rated
capacity, the tablet fails this test.

29. If battery capacity tested is less than the rated
capacity, the tablet fails this test.

31. Screen separation is a common problem seen with
lower-quality tablet PCs.

32. Tablets should be tested for screen adhesion to ensure
that screens won’t easily separate from the tablet
during normal use.

33. To test screen adhesion:

34. To test screen adhesion:
1. Apply 3M tape to the tablet screen

35. To test screen adhesion:
2. Tear the 3M tape off the screen
1. Apply 3M tape to the tablet screen

36. To test screen adhesion:
2. Tear the 3M tape off the screen
1. Apply 3M tape to the tablet screen
3. Check that the screen is still firmly in place

38. Vibration testing simulates forces products are
subjected to during transportation and shipping.

39. An important part of product inspection for tablets,
vibration testing involves the use of a vibration table.

40. An important part of product inspection for tablets,
vibration testing involves the use of a vibration table.

41. The International Safe Transit Association (ISTA) provides
procedures for vibration and related testing for consumer
products.

42. To conduct vibration testing for tablet PCs:

43. To conduct vibration testing for tablet PCs:
1. Use units that have already passed AQL defect inspection

44. To conduct vibration testing for tablet PCs:
2. Place units in their retail packaging on the vibration table
at 200RPM for 2 hours
1. Use units that have already passed AQL defect inspection

45. To conduct vibration testing for tablet PCs:
2. Place units in their retail packaging on the vibration table
at 200RPM for 2 hours
1. Use units that have already passed AQL defect inspection
3. Check the units for functionality and performance

46. If the units tested maintain full functionality and
performance, the tablets have passed vibration testing.

48. Environmental testing for products simulates how
extreme conditions can affect product functions.

49. In the case of tablet PCs, it’s important to check
functionality after prolonged exposure to high
temperature and humidity.

50. An environmental chamber, or climate chamber, is an
enclosure used to carry out such testing.

51. A number of standards for environmental chambers
exist, including:

52. A number of standards for environmental chambers
exist, including:
• International Organization for Standardization (ISO)

53. A number of standards for environmental chambers
exist, including:
• International Organization for Standardization (ISO)
• American Society for Testing and Materials (ASTM)

54. A number of standards for environmental chambers
exist, including:
• International Organization for Standardization (ISO)
• American Society for Testing and Materials (ASTM)
• The Institute of Environmental Sciences and
Technology (IEST)

55. To carry out environmental testing for tablet PCs:

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

57. To carry out environmental testing for tablet PCs:
1. Keep the units in an environmental chamber with a temp
of 55 C +/- 2 C and a humidity of 85% for 8 hours
2. Check the tablets’ functions and performance

58. If the units tested maintain full functionality and
performance, the tablets have passed environmental
testing.

59. If the units tested maintain full functionality and
performance, the tablets have passed environmental
testing.
