One feature of HZO that brings a twinkle to the eye of a product designer is that our technology requires no changes to form, fit or function. With HZO, an industrial designer doesn’t have to find ways to work around clunky seals or gaskets. Still, HZO faces a tad of skepticism, particularly since our technology, which inoculates devices from dust and liquids, is microns thin, optically clear and applied to the inside of electronic devices.
You may be wondering how an electronic manufacturer would know that HZO had been applied to a PCBA. The straight up answer is there is a machine for that. Specifically, companies can use a thin-film measurement system like the ones produced by Filmetrics, a U.S. company based in San Diego.
A Filmetrics system measures the thickness of thin films including Parylene, which is the chemistry used by HZO. Filmetrics sells test equipment to measure transparent and translucent films that range from 1 micron to 1 millimeter in thickness with an error range of mere angstroms. The tool HZO employs uses spectral reflectance where light is reflected off the film and then analyzed over a range of wavelengths. Our Chemist, Dr. Sean Clancy, is an advocate of optical techniques to measure thin films because they are accurate, do not destroy the film, and require little to no preparation of the testing samples.
HZO offers a significant advantage over alternative methods of liquid and dust proofing for electronics. And now, the measurement tools are in place to prove that HZO meets customer requirements. It’s wonderful to be transparent.
