Dear Technet,

Would like to determine if there is a specification to check for the
surface contact resistant of the board when a metal dome (form the keypad)
is pressed on top on the boards. The resistance tolerance should be well
around +/-0.001 ohm. The reason is to address any intermittent contact
(like increse in resistnace) if there is an oxide layer or contamination on
the boards.

Appreicate any inputs.

Regards,
YH Koh
