Description
Testex Press-O-Film Conventional Testex tape is available in a variety of thickness ranges for measuring substrate roughness using analog or digital micrometers. It is available in the following:
- Coarse Minus.
- Available in rolls only. Measurement range is 0.5 – 1.0 mils / 12 – 25 µm.
- Coarse.
- In rolls, the measurement range is 0.8 to 2.5 mils (20 – 64 µm)
- In updated strips, the measurement range is 0.8 to 2.0 mils (20 – 50 microns)
- X-Coarse.
- For both rolls and updated strips, the range is 1.5 to 4.5 mils (38 – 115 microns)
- X-Coarse Plus
- In rolls, the range is 4.6 – 5.0 mils (116 – 127 µm)
- In updated strips, the range has been increased to 4.0 – 6.0 mils (100-150 microns).
- Note – the X-Coarse Plus versions cannot be used interchangeably.
Testex Press-O-FIlm Optical Grade replica tape is designed for use with the PosiTector RTR 3D tape reader probe. It provides high quality surface data files (.sdf) which can be used for peak density measurements as well as traditional surface profile readings. It is currently available in rolls only, in the following measurement ranges:
- Coarse. Measures 0.8 to 2.5 mils (20 – 64 microns)
- X-Coarse. Measures 1.5 to 4.5 mils (38 – 115 microns)
