Automated Touch Screen Actuation Testing

This video outlines a custom designed automatic system used to test the actuation force of touch screens for quality control.  A Mecmesin computer-controlled MultiTest-i force measurement system combined with an x-y table is used to create a "point map" of actuation force at set positions.  The x-y table moves the touch screen in a pre-programmed path at sub-millimetre accuracy.  At each pre-programmed location the test proble is lowered to "touch-on" the screen and the actuation force is captured as electrical contact is made.
