Press-O-Film provides inspectors and researchers a simple way to obtain an impression of a surface. The tape consists of a layer of crushable plastic microfoam coated onto a polyester film of highly uniform thickness.
When compressed against a roughened material, Press-O-Film accurately replicates details of its surface roughness. For use with the Testex 7326STX Dial Thickness Gauge.
Overview
The impression can be studied in several ways:
- A Testex 7326STX dial thickness gage can be applied to the replica for field measurement of the average maximum peak-to-valley roughness, or “profile,” of a replicated surface.
- A digital thickness gage such as the PosiTector RTR can also field-measure profile and bridge the gap between tape grades by incorporating automatic linearization.
- An optical profiling interferometer or confocal microscope can be used in laboratory settings to produce maps of the replica’s surface topography. This is most appropriate to study of subtle features at the microinch (25 nanometer) level.
Specifications
Testex Press-O-Film replica tape is available in a variety of thicknesses to facilitate profile measurement in differing ranges.
The primary range for measurement with replica tape is 0.8 to 4.5 mils (20 to 115 um). Use of Coarse Minus grade (<0.8 mil or <20 um) or X-Coarse Plus grade tape (>4.5 mil or >115 um) should be restricted primarily to checking measurements at the lower and upper ends of the primary range.
| Grade (descriptive) |
Range When Used With Gage (mils) / (um) |
| Coarse | 0.8 to 2.5 / 20 to 64 |
| X-Coarse | 1.5 to 4.5 / 38 to 115 |
| X-Coarse Plus | 4.6 to 5.0 / 116 to 127 |
