11.2 Mechanical characteristics
Note 1: Force test condition, Input DC 5V on X direction, Drop off Polyacetal Stylus (R0.8), until output
voltage stabilize, then get the R8.0mm Silicon rubber and do finger Activation force test. Next step, 9
points.
Note 2: Measurement surface area conditions, Scratch 100,000 times straight line on the film with a
stylus change every 20,000 times with Force: 250gf, Speed: 60mm/sec by R0.8 polaceteal stylus.
Note 3: Pitting test, Pit 1, 000, 000 times on the film with R0.8 silicon rubber with Force: 250gf and
Speed: 2 times/sec.
