In conformal coating, there are many International, National and internal company standards for manufacture of coating materials, processing and inspection. The UL standards (and qualification) are used to qualify a conformal coating material to a certain specification. Therefore, it is

Why may I have to clean my circuit board before conformal coating?
Whether to clean circuit boards before conformal coating is a well discussed problem. However, I thought it may be interesting to summarize the reasons for considering the cleaning process before coating as it can be critical to the success of
Five key facts about Fluoropolymer Nano-coatings
There are many fundamental differences in coatings. The Nano-coatings are no different. Here are five key facts about them. Fact 1: The Nano-coatings are extremely thin A Nano-coating is normally applied a lot thinner than an equivalent protective coating.
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
What is a fluoropolymer coating?
A fluoropolymer coating is a material comprised of fluorocarbons and characterized by carbon-fluorine bonds. Fluorocarbons are not susceptible to Van der Waals force. This gives the coatings their signature properties. That is that a fluoropolymer coating is non-stick and friction
How thick should I apply my conformal coating?
A regular question asked in conformal coating is how thick should the coating film be? 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
Choosing the right conformal coating application process
Choosing the right process for your conformal coating production line is a complicated and involved process. It normally is a case of balancing a number of factors and making compromises. This is because of the three major parts of the
How do I brush coat my conformal coating?
The application of conformal coating using a brush to apply the material to the circuit board is a common practice. This can be done as a complete production process or as a finishing task before final inspection. The technique involves
Why use conformal coatings?
There are several reasons for using a conformal coating or Parylene to protect a printed circuit board (PCB). These reasons include: – High insulation protection – High moisture and humidity protection – Chemical and temperature resistance – Ruggedisation – Improved
What application methods are available for applying conformal coating?
Conformal coatings can be applied to printed circuit board assemblies in many different ways in the production environment. Listed below are the common methods of applying the conformal coating materials. – Brushing – Aerosol Spray – Batch Spray – Selective
