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

Uncategorized

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.

How thick should I apply my conformal coating?

Uncategorized

So, a question I am regularly asked is,“What is a good conformal coating thickness for my printed circuit board?”

Well, the simple answer is thick enough so the conformal coating works and protects the circuit board. But not too thick as this can cause problems for the circuit board in the long term.

After all, the performance of the conformal coating is dependent on the material applied. But, it is possible to quantify this a little more.

Help for determining the right conformal coating thickness

First off it’s probably best to use guidelines from International Standards like IPC A 610. These standards specify the conformal coating thickness based upon the generic material types like acrylics, polyurethanes, and silicones. Further, you can also reference this data against the material manufacturers technical recommendations.

Combining these two pieces of information should give you a target range for a suitable thickness. However, ultimately, the coating thickness is down to the user.

How you decide if the conformal coating thickness is good enough is up to you. Too thin and you will not protect the circuit as effectively as you may need. Too thick and you could have reliability issues in the future. So, monitor your conformal coating thickness with care.
How you decide if the conformal coating thickness is good enough is up to you. Too thin and you will not protect the circuit as effectively as you may need. Too thick and you could have reliability issues in the future. So, monitor your conformal coating thickness with care.

So what do the IPC Standards recommend when considering coating thickness?

The IPC A 610 standard defines ideal thickness values as:

  • Acrylic: 30-130ΞΌm
  • Polyurethane: 30-130ΞΌm
  • Silicone: 50-210ΞΌm

However, this is not the end of the story. Using the target coating thicknesses as an absolute value can be problematic.

The reality is that the thickness will vary massively across the circuit board due to many factors including the surface tension of the liquid, the surface energy of the board surface, the design of the board, the material properties and the application method used.

So, there may be areas on the board that could fall outside of the range where the coating thickness will be less or more than the ideal values. Therefore, it is highly recommended that the range should be considered as an average value across the board for the conformal coating thickness.

In fact, the IPC go further and suggest using flat test coupons coated in the same way as the process you use for the circuit boards. Then, these test coupons are measured against the standards. In the end how you decide if the coating thickness is good enough is up to you.

Too thin and you will not protect the circuit as effectively as you may need. Too thick and you could have reliability issues in the future. Β So, monitor your conformal coating with care.
