Abstract :
It is shown that wipe distances of less than 10 mils produce stable contact resistance values at a normal force of 120 g for a hemisphere-flat geometry, even on dust-covered surfaces. An ellipse-flat geometry is less effective, although effective wiping action is observed at distances less than 20 mils. A cylinder-flat geometry shows marginal wiping effectiveness
