Release Notice
Placing the keyboard such that the direction of keyboard operation is vertical, the
maximum pulling force required to remove a key cap shall be measured. The above
values are based on initial keycap removal test cycle. No permanent damage to any
component of the key switch should occur and no removal of any other component
(w/exception of leveling mechanism or wire on multi-wide keycaps) except the keycap
when the keycap pull test is performed. Keycap shall be easily replaceable by user.
(2) Keyboard stop strength:
There shall be no sign of damage, mechanically or electrically to the keyboard or point
stick (if applicable) when the keyboard is placed such that the direction of keyboard
operations is vertical, and a static load of the following force is applied in the direction
of keycap operation for a period of time or in the direction of stick operation.
A test shall be performed with the keyboard fixed to avoid keyboard warp and a test
probe 13.0mm in diameter minimum applied made of a high Durometer rubber so as
not to damage the keycap or point stick cap.
Operation Direction Load, N (Kg) Period (second)
Key cap Z 29.4 (3)
60
Stick XY 39.2 (4) 60
Stick Z 98 (10) 60
(3) Cable Strain Relief
The Cable, if applicable, on the keyboard shall have a minimum bend radius of 1.0mm
and a Strain Relief of 0.45kg in any direction.
(4) Flex Termination/Connector Mate and Un-Mate Life
The Keyboard Connection to the system (or Touchpad) interface shall support
twenty-five (25) mate/un-mate cycles at all possible angles of insertion (determined on
a product by product basis via Dell Engineering) without any functional degradation or
change in signal integrity outside of specification range.
(5) Keyboard Bending Strength
