Nano-coatings are being used all the time to protect electronic circuit board assemblies. This is because the base materials they are formulated from are fluorinated polymers that have very different properties to traditional conformal coatings. So, how are the Nano-coatings
conformal coatings
What are the main methods for cleaning contamination from a printed circuit board before conformal coating?
Successful cleaning of electronic circuit board assemblies can be achieved by a variety of techniques. These include: • Aqueous wash • Semi-aqueous wash • Solvent & chemical wash • Plasma cleaning Each of these methods can effectively remove contamination. However,
What sectors are acrylic conformal coatings used in protecting electronic circuit boards?
Acrylic conformal coatings are used in protecting circuit boards in every sector of the modern world. Historically, they are the oldest material to be used as a conformal coating and the acrylic resin continues to dominate for the time being.
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
Do you need UL qualification for your conformal coating?
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
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
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
How do I measure conformal coating thickness?
Measuring the conformal coating thickness on a printed circuit boards assembly (PCBA) is not a simple process. The fact of the matter is the circuit board is generally not flat for the majority of the surface. Therefore, the uneven nature
What is Plasma coating?
Plasma coating is the application of a nano-coating material onto a surface via a plasma. The material is injected into the plasma via a jet nozzle. The plasma excites the coating material and this increases the coatings reactivity. The
