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
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
Why is cleaning “no clean” flux residues difficult and how to get it right?
No clean flux residues on printed circuit boards are not designed to be cleaned easily. Fact. Therefore, cleaning the residues left behind by a no clean flux process is one of the most difficult tasks when considering cleaning. How do
The ABCs of plasma cleaning for improving surface adhesion and processing
The ABCs of plasma cleaning for improving surface adhesion and processing Plasma cleaning is a process that is gaining more popularity in thin film applications due its highly effective performance on cleaning and modifying surfaces. What is Plasma? Plasma is
Why use masking boots in a conformal coating process?
Custom masking boots can provide protection for many different types of components on a circuit board from ingress of coatings. In fact, they can form an integral part of a full masking solution in all of the conformal coating
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
What is Atomic Layer Deposition (ALD)?
Atomic Layer Deposition (ALD) belongs to the family of chemical vapor deposition methods (CVD). It is a nano-scale deposition process within a vacuum chamber. The deposition process forms ultra-thin films (atomic layers) with extremely reliable film thickness control. This provides
