The Man Perfecting Electronics Waterproofing Design

He Was Engineered to Build the Perfect Waterproof Device Design 


Earlier last year, we had the opportunity to speak to Marketscale for a podcast, in order to pull back the curtain and give engineers, manufacturers, and consumers a bird’s eye view of how we do things at HZO when we offer waterproofing services for manufacturers. Zsolt Pulai, our Executive Vice President of Technology and Engineering naturally came to mind first when we decided who should do just that.

Here’s why: 


He Was Engineered to Build the Perfect Waterproof Device Design 

Here’s what Zsolt said about how his past shaped the future of waterproofing technology:

“My grandfather was an engineer, and my father was an engineer. My brother is an engineer, and I am an engineer. They are all mechanical engineers. And I’m a software and factory automation engineer by training. It’s all part of the engineering group. I was always around engineering and the creation of something new, something important, something unique.”


He Knows Waterproofing Design Like the Back of His Hand 

“We design everything in-house, we know everything from A to Z. We know the whole aspect of the project. We know the whole every little detail. And by understanding the whole aspect, I can be 100% positive we can do a much better job with the outcome. So that’s very important for us,” says Zsolt. 


He Understands that Nano Coatings for Waterproofing Are a Really a Current Affair

Globally, we’re facing a device dilemma. We’ve built these complex, tiny devices that can be so powerful but at the same time, can instantly fail after short exposure to water. Zsolt weighed in: 

“Over 300 million phones are lost each year to water damage that’s costing the industry close to 100 billion dollars. You can imagine this is just one example. Devices surround us – the Internet of Things, the automotive, the medical, industrial verticals and more, there’s a significant need to protect these devices and sensors and circuits. We came up with a futuristic solution, maybe. The word nano coding sounds futuristic, but indeed, it’s happening today. Nano coating is a very thin film, a very thin layer of protection. You can imagine the thickness of your hair is maybe a hundred microns. We are talking about 10 percent of that or even one percent of it. But it’s a very robust protective layer and it protects against the environment or any other water-related damages.”


Zsolt Explained How Nano Coatings Work

“Mechanical seals want to keep the water or the environment outside of your device. That’s not what we do. We make sure that even if the water is present inside of an electronic, it won’t be damaged. Imagine it this way: if you have a PCB board, we wrap this board in plastic. This “plastic” keeps the elements, like water from being able to contact the electronics, so even if water seeps inside, it’s not an issue.”


Not Just Anyone Can Perfect Waterproofing Electronics Services

“HZO has unique equipment and a unique process. They’re designed and built in-house, opening up possibilities to what we can do with our technology and equipment. The coating equipment is the heart of the system. But we also have unique pre and post equipment as well where we prepare the boards for coating, and after coating, we do some post-processing. You don’t need this coating, for example, on the connector itself. You have to make sure that the connector is conductive.

Our workhorse is Parylene and it’s like a plastic material. The coating is done inside of our equipment chambers. The coating literally goes everywhere. Tiny little cracks on the device, tiny little imperfections on the device when it goes under components, it literally does everywhere. But again, there are areas that don’t need coating. So you put a masking material on these parts beforehand. But then, of course, you’ll have to remove the masking material afterward. 

This is the process. But at HZO, we’re able to have a full mass-production scale, fully automated system to do the masking, coating, and then the demasking. I think the important thing here to understand is that we build proprietary equipment and processes needed to successfully coat a multitude of these electronic electrical components and printed circuit boards in a mass production environment where we can coat several hundreds of thousands to millions of pieces daily. 

And our ability to scale like this is repeatable, we provide the same quality over and over and over again.” 


Zsolt Wrapped Up By Explaining What Was Next

“I am proud to say that globally we are the largest provider of these solutions with electronics production and we are further developing our new coating capabilities and techniques. We stay ahead of the rapidly changing markets of requirements from our customers. I think this is very important to understand. In the future, we are building new and optimized machines. It’s never enough. Even if we have the best, the nicest, the fastest equipment, we don’t stop here. If we did, we would not call ourselves engineers, if we did not want to do more innovation. So we are building new optimized machines, new optimized processes.”
