Reliability Testing Specification

Individual units must pass any and all of the following tests. The order of testing is subject to the tester. Passing the test is defined as functioning properly without significant damage; including but not limited to mechanical failure, electrical failure, chips or cracks in the housing or significant changes in the tactile feel.

Mean Time Between Failure (MTBF)

  • The unit shall have an expected MTBF under operating conditions of not less than150,000hours (on condition 6 hours per day operation, 250 days per year with 99%confidencelevel).

Drop Shock with Bare Unit K

  • Drop the unit from 60cm height onto 5 mm carpet, on the top, bottom and 3 sides without cable side of the unit (1 time for each side). The unit should be without damage. Damage is defined as failure of the unit to function properly, chips in the housing, or mechanical failure of any of the parts.

Drop Shock in Gift Box

  • Drop the unit in box from 91cm onto a concrete floor, on the 4 corners and 6 sides of the box(1time for each side). Resulting damage should be minimal and shall not allow for contents to escape from packaging

Drop Shock in Carton

  • Unit shall survive a drop test in the weight of product carton on 1 corner, 3 edges and6sidesfrom the height onto a concrete floor (1 time for each side).
  • </= 9.5kg------91cm
  • </= 18.6kg------76.2cm
  • </= 27.6kg------61cm
  • </= 45.3kg------45.7cm

Temperature & Humidity Operating(Vcc=5v, 100mA max) Test

  • The unit is kept at the temperature of -10 to 65 degrees Celsius and relative humidity of 5%to90% for 51 hours and then left at ambient room temperature for 2 hours.

Heat Cycle Test for Shipment Pattern

  • -10 degrees Celsius to 60 degrees Celsius under 5% to 90% relative humidity with total time of 50 hours, and then left at ambient room temperature for 2 hours.

Cable Bending Strength

  • The cable must withstand bending 60 degrees any direction from its centerline; the detail testingconditions as followed:
  • Load: 100 grams force
  • Angle: +/-60 degrees around 25.4mm diameter
  • Speed: 30 cycles/min
  • Criteria: Min 5,000 cycles, with no visible damage and no breakage in each wire.

Drop Shock in Carton

  • Vibration
  • Unit shall survive a vibration within a frequency range of oscillation: 5~55Hz withamplitude0.38mm(p-p) for X, Y and Z axis, each 30min. (Vibration acceleration:20 m/<s square>rms)

Reliability Performance

After having been subjected to any and all of the reliability tests outlined in section 5.0, the unit

shall meet the following performance specifications:


Button Actuation: All of the keys are with specially good feeling , And since when used, the finger touch the silicon , so it can have a special soft feeling . Water proof : Whole keyboard can put water proof , and for this feature can make the whole keyboard dusty proof and also Antibacterial function
