Wafer Polishing
Tactile Pressure Indicating Sensor Film
Pressurex® is a thin flexible mylar film that reveals pressure distribution and magnitude between any two contacting surfaces. Pressurex® indicate precisely how the pressure between surfaces occurs under different materials, patterns, pressures and designs. The spatial resolution is fine enough to expose minute surface defects, trends and other imperfections as well as showing lower / higher pressure areas of contact to improve the design and reliability of the finished products.
Upon the application of force the microcapsules rupture, producing an instantaneous and permanent color change. Like Litmus paper, the color intensity of Pressurex® is quantifiable; the color intensity reveals precisely what pressure level (PSI or kg/cm²) was applied at any discrete point on the surface of the film.
