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
coatings
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
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
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
What sectors are fluoropolymer coatings used?
Fluorinated coatings are a relatively new technology. They are also continuously evolving. They are used in nearly all areas of industry including: – Aviation – Aerospace – Defence – Automotive – Industrial – Oil & Gas – Electronics – Medical
