By 2030, electronics will account for 50% of a car’s total cost worldwide with the average vehicle utilizing as many as 50 processors. These processors perform critical functions that keep us and those around us safe. We are dependent upon every sensor, camera, module, and assembly for proper operation of the vehicle.

Road Hazards Ahead

Various vehicles including cars, trucks, buses, and more are exposed to a wide variety of contaminants on the road that are a threat to the electronics on board. These contaminants compromise the functionality and warranties promised in the quality testing mentioned above. These threats include:

  • Oil
  • Gasoline
  • Water (rain, standing)
  • Pollutants in the air
  • Salts
  • Antifreeze
  • Splashes from road grime
  • Sticky beverages spilled on the console area of the cabin
  • Other corrosive substances

Dependability of an automotive electrical component comes through proper protection of the unit itself. This is done by protecting the circuitry directly from the harmful liquids and substances mentioned above. Traditionally, this protection has come from legacy solutions such as traditional conformal coatings including silicone and acrylics as well as mechanical seals, enclosures, and gaskets.

These solutions, while deemed effective in their day, have many drawbacks. These shortcomings include:

  • Voids in traditional conformal coatings.
  • Significant weight addition due to heavy conformal coatings.
  • Rubber gaskets expand and contract in temperature fluctuations.
  • Rubber gaskets and enclosures can become dislodged on bumpy and rocky roads.
  • Oxidation and deterioration of rubber gaskets.

Because of these weaknesses, critical automotive circuitry, sensors and components, can and have failed, causing loss of property, brand trust, and even life. When human life is on the line, automotive brands and manufacturers in all tiers cannot afford to cut corners or rely on aging solutions. In this new age of automotive electrification and sophistication, new solutions and thinking is required.

The Best Alternative to Auto Insurance You Can Get

Thankfully, there are new protection solutions already available on the market to ensure the reliability and safety of vehicles on the road carrying precious cargo. These solutions come in the form of HZO’s thin-film coatings (such as Parylene and plasma based nanocoatings), designed specifically for automotive applications. These new protection methods provide solutions for automotive engineers designing current and future vehicles:

A superior substitute to existing automotive electronics protection solutions. Thin-film protective coatings and nanocoatings within HZO’s Spectrum of Protection™ solve the short comings of existing protection solutions by offering:

  • No compromising voids in thin-film coatings
  • Virtually no incremental weight in an age of automotive lightweighting
  • Ability to perform in significant temperature ranges
  • No risk of protection compromises due to bumps or jarring on the road
  • No degradation in corrosive and caustic environments

These automotive coatings offered by HZO ensure that the aging protection methods employed by the automotive industry today can be augmented or replaced altogether for a more reliable, future proof solution.

The perfect protection partner for the next generation autonomous vehicles. As processors and sensors in upcoming vehicles become smaller, more compact, and more sophisticated, new protection solutions are needed that traditional methods simply cannot match. Engineers and designers require the use of complex circuitry found in driven and driverless cars including Lidar, cameras, steering systems, navigation, infotainment, security, and more that have never been seen on the road until today. Cars have become complex computers more than mechanical modules. With this complexity comes the challenge of protection.

Traditional methods cannot adequately be applied and installed in the tight crevices and on the complex circuitry of tomorrow’s vehicles. Given the sheer number of automotive PCBs, sensors, wiring and more in the vehicles of the (near) future, traditional protection manufacturing methods simply are not sufficient.

Thin-film and nanocoatings found within HZO’s Spectrum of Protection™ provide the ideal protection for future automotive electronics because of their ability to:

  • Effectively cover complex circuit and module topography.
  • Be capable of high-throughput application in existing manufacturing lines.
  • Offer cost effective and affordable pricing.
  • Proven and warrantable protection.
  • Primary or secondary means of protection (when failure isn’t an option).
  • Enable vehicle lightweighting due to virtually no added weight.

HZO draws from a wide range of materials to offer just the right amount of protection for your automotive coating needs based upon your design specifications and cost requirements. Microns-thin application of both Parylene or a plasma-based nanocoating can literally save grams (or even kilograms collectively) off the design of your vehicle.

Manufacturers owe it to their customers to make sure their vehicle’s computer, electrical assists, and other forms of electrical communications will still function in a safe and accurate manner despite having been exposed to corrosive and or flammable liquids.

HZO’s specialized and dedicated mechanical engineers are standing by to provide you the right solution at the right price-point.
