Description
Testex Press-O-Film replica tape is available in a variety of thickness ranges for measuring substrate roughness. The primary range for measurement with replica tape is 20 to 115 µm (0.8 to 4.5 mils). Use of Coarse Minus grade (<20µm or 0.8 mil) or X-Coarse Plus grade tape >115µm or >4.5 mils) should primarily be restricted to checking measurements at the lower and upper ends of the primary range.
Testex Press-O-FIlm Optical Grade replica tape, when used with the PosiTector RTR 3D model, provides higher quality surface data files (.sdf) than conventional replica tape. Optical Grade Replica Tape is available in Coarse or X-Coarse.
