Have you ever drop you cell phone into water?

Or sprinkle the water on the keyboard?

Think about it——you take down the keyboard, dry the components up, then assemble it again, Wow, there are so many components left!

Now, the problem is solved. A kind of keyboard that can be used in water is available.

Thanks to Parylene! And chemical vapor deposition (CVD)!

Parylene

Parylene is a kind protective polymer material, it has good penetration and can be deposited inside the component forming a uniform transparent insulation coating without pinhole. Waterproof, mouldproof, anti-salt spray, parylene provides a complete high-quality protective coating for components. According to the different molecular structure, Parylene can be split into Parylene N, C, D, HT, F type. The type used on the PCB of keyboard are Parylene N.

Chemical vapor deposition (CVD) process

Compared to the traditional coating technology, the CVD process completely overcome the shortcomings, the coatings are uniform, no pores, and environmental protection.

Parylene can not only be used on the keyboard, but also used in optoelectronic materials, magnetic materials, multi-functional waterproof clothing, cultural relics protection and other fields. In addition, due to biocompatibility, it also can be used as protective coating for implantation devices and medical equipment probe in medical field, with insulation, corrosion and other properties.

For a long time, due to the limitations of equipment and experimental environment, Parylene has been used in high-end products. With the rapid development of science and technology, we believe that parylene will step into daily life.
