cleaning

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:

Why use plasma cleaning for cleaning circuit boards?

For a conformal coating to be effective in protecting a circuit board it should be applied evenly over the circuit board assembly and it should have good adhesion.

Otherwise, the circuit may suffer an early failure in the field.  

For good coverage and good adhesion the surface properties of the circuit board should be compatible with the conformal coating.

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 you “clean” no clean flux residues if you have to?

Whether a flux residue can be cleaned effectively depends on the cleaning materials saponification factor and its compatibility with the residues.

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 an energy-rich gas state that can be used to modify the surface of a product to improve its performance.

How does Plasma work?

Plasma technology is based on a simple physical principle.

What is Plasma?

Plasma is an energy-rich gas state that can be used to modify the surface of a product to improve its performance. This modification can be improving the adhesion of a surface or changing the surface characteristics.

Plasma technology is based on a simple physical principle.
