Five key facts about using fluoropolymer Nano-coatings for protecting printed circuit boards

Blog, Fluoropolymer

June15-3

  1. A Nano-coating is hydrophobic. It repels water from the surface of the circuit board and water will not wet the circuit.
  2. The Nano-coatings are extremely thin (<2um). They are very different to traditional conformal coatings.
  3. Nano-coatings do not require masking. The circuit board can be completely submerged in the liquid with no masking applied without damaging components.
  4. They have excellent chemical resistance due its fluorine bonds. The Nano-coatings are perfect to protect against chemical attack.
  5. Using a Nano-coating is a fast simple process. The coating can be dipped quickly, without masking, and the coating dries extremely fast.

Three key reasons to use a Molecular Vapor Deposition (MVD) process to protect a circuit board instead of conformal coatings

Blog, Molecular vapour deposition

Molecular Vapour Deposition (MVD) is a new process introduced to the electronics coating market.

MVD is a hybrid coating technique using ALD (Atomic Layer Deposition) and CVD (Chemical Vapor Deposition) coating processes in combination.

The method uses multiple layers of ultra-thin coatings with differing properties to build a completely protective coating with a final hydrophobic Nano coating as a top layer.

MVD

Here are three key points that strongly suggest you should find out more about this coating:

  1. The physical and electric performance of the MVD coating is superior to other materials like conformal coatings and Parylene. Parameters such as Water Vapor Transmission Rate (WVTR), hydrophobicity, coating adhesion, dielectric strength and temperature performance (>250°C) are vastly improved when protecting circuit boards.
  2. The MVD coating does not require masking to protect sensitive components and electric connectivity in connectors is easily made even when coated. This is because the coating thickness of the MVD material is x10 less than that of Parylene.
  3. The cost of process is much lower than all other protective materials due to the fact that raw ingredients are low cost and no masking is required.

There are many other performance criteria that make this material a really interesting process that could change perceptions.

Nexus article on, “Outsourcing your conformal coating project – The key points”

Blog, conformal coating

Nexus

Nexus, the independent conformal coating resource, recently published an article on subcontracting your conformal coating services out to a third party.

I thought it would be useful to signpost people to this article and republish the points they raised since getting it right can be so critical in outsourcing.

Nexus identified that there are, “three key points to consider when choosing a subcontractor”.

These three key areas were:

  1. Quality
  2. Turnaround time
  3. Price

They stated that,

“if you get these three key areas correct then you have succeeded.

Everyone will be happy and there are no more problems with conformal coating.”

(Source: Nexus).

However, within each of these areas, they outlined a lot of questions that should be asked to ensure you get it right.

Those points were examined in detail with some real insight into subcontract services.

If you are considering outsourcing your conformal coating then I can recommend reading the article now.
