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
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 the science behind Molecular Vapour Deposition (MVD)?
TFP is now offering a new coating process, Molecular Vapour Deposition (MVD), that may be able to meet all of the environmental demands for circuit board protection and other surfaces. The process could also be highly cost-effective. This process is
What standards should I use for my conformal coating?
There are many international, national and internal company standards for conformal coating processing and inspection. The role of the standard is to give a guideline for process control and ultimately reliability of the circuit board. The International inspection standards
How do I dip coat my printed circuit board in conformal coating?
A conformal coating can be applied in many ways to a printed circuit board assembly (PCBA). The many methods include spraying, brushing and dipping. Dip coating is one of the most efficient methods for application of conformal coatings and is
The ABCs of Plasma Coating
Plasma coating is the application of a Nano-coating material onto a surface of a substrate via a plasma gas. Plasma technology is based on a simple physical principle. Matter changes its state when energy is supplied to it. Solids
Why is adhesion important for conformal coatings?
The durability and performance of conformal coatings can depend on two basic properties. These are the cohesion and the adhesion of the coating. Cohesion is the inner strength of a material and is associated with the strength of the molecular
