How HZO Equipment is Helping Revitalize Thin Film Coatings
Over the past few weeks and months we’ve been talking a lot about HZO Technology; the testing we perform, the tools involved and the processes that make it all possible.
To follow up on the HZO patented application process video we revealed a few weeks back we wanted to go into a little more detail about HZO’s proprietary equipment works and why it matters to companies looking to differentiate their products or improve performance and longevity.
A New Approach to Parylene
HZO thin film coatings are applied through a chemical Vapor Deposition Process, and our Parylene-based material makes a transformation from raw, organic powder form a thin film polymer coating. The application of this material itself is also part of the explanation as to why we don’t treat aftermarket devices for consumers, and how it is that HZO technology is able to provide corrosion prevention for so many industrial components, sensors and other electronics, as well as water and sweat protection for consumer electronics.
The equipment itself comes in three sizes and is adaptable to scale to large volume throughput, having been proven in mass production with high uptime and high yield.
HZO’s proprietary process also utilizes the largest deposition chamber size in the industry and minimizes flow interruption with low cycle times compared to conventional Parylene equipment.
Here’s a high level overview of what happens in an HZO machine:
- After any masking and other pre-production preparations are complete, units are loaded onto specially designed trays and racks and inserted into the vacuum deposition chamber of one of HZO’s proprietary machines.
- Thousands of PCBs, components, sensors or other electronics can be processed at a time, depending on the size of the assembly and piece of HZO equipment utilized.
- Based on the surface area of units in the chamber and the target thickness, a precisely calculated amount of Parylene-based material is added to the machine in powder form.
- This organic polymer blend travels from one end of the equipment to the other via a chamber, being exposed to high temperatures during the migration and converting the raw material from powder to vapor.
- Following the thermal activation, the vapor enters the vacuum deposition chamber at ambient or room temperature where monomer particles land on any exposed surface, bonding one by one to form particle chains.
- These monomer chains stack on top of one another, getting into very small crevices and other geometries to form a very uniform, conformal, thin film barrier.
- Once deposition is complete the solution is permanent, and no additional time is requiring for curing.
The resulting thin film material prevents water from reaching the protected areas.
So what does it all mean for your business? HZO has taken a time tested and proven material and dramatically improved the processes for masking, de-masking and application to align with the requirements of a wide range of industries as it relates to volume, protection levels and overall performance. Not just a temporary barrier against water or sweat, but to long term exposure in harsh chemicals, liquids and gases that matter to industries ranging from oil and gas and automotive to military and mining.
