Five key facts about Parylene for protecting electronic circuit boards

Parylene is a high performance coating used to protect electronic circuit boards against environmental attack.

It is an organic polymer thin film that is created via a controlled Chemical Vapor Deposition (CVD) process.

This involves the vaporization and subsequent pyrolysis of a feedstock (dimer), resulting in the formation of a monomer that is then polymerized in a vacuum chamber (at low pressure and at room temperature).

Ten reasons to use Molecular Vapor Deposition (MVD) in protecting electronic circuit boards

Molecular Vapor Deposition (MVD) is a new coating from Thin Film Partners that uses a hybrid coating process of alternating layers of ALD (Atomic Layer Deposition)  and CVD (Chemical Vapor Deposition) films combined with a hydrophobic final top coat.

The MVD method uses multiple alternate layers of these ultra-thin coatings with differing properties to build a completely protective coating.

Why use silicone (SR) conformal coatings to protect electronic circuit board assemblies?

Silicone (inorganic) conformal coatings can be very different in nature to the organic chemistry coatings like the acrylics and polyurethane materials.

For example, they tend to have a much wider temperature range of operation compared to the other conformal coatings.

There are many fundamental differences in coatings. The Nano-coatings are no different.

Here are five key facts about them.

Coating LEDs with Molecular Vapor Deposition (MVD)

Coating LEDs to protect them from the harsh environments they are placed in is big business.

The volume of manufactured LEDs globally is growing at an exponential rate and there is no end in sight.

However, the challenges to protect the LEDs from long-term failure are not small especially in an outdoor environment.
