How to completely remove Parylene from a circuit board

Removing conformal coatings from a printed circuit board (PCB) is a hard process to do well. Removing Parylene coating is even more difficult.

The problems are many but a key reason is that the Parylene coating itself is chemically inert. It has a very high chemical resistance so the solvents don’t work well.

However, from recent research we have a new process for completely removing Parylene from the surface of a circuit.

Find out now how much money you can save by using our Parylene removal service.

Are SCH Technologies conformal coating masking tapes and dots ESD safe?

conformal-coating-masking-dots-and-tapes-500

Our masking tapes and dots are not made of ESD material so they are not ESD safe.

The problem is that conductive material does not make good masking tape for conformal coating. There are issues with properties like adhesion and flexibility.

However, you can overcome the static generated by the products by using ESD ionising blowers and fans around the area.

Combining this with your standard ESD protection like mats, wrist straps etc should make the process completely safe.

10 Reasons To Use Parylene Coating for Circuit Board Protection

  1. True Conformal Coating. Parylene coating is completely conformal to the surface of the Circuit Board. This means that the coating has a uniform thickness and is pinhole free.
  2. Very Low Permeability. Parylene coating provides an excellent barrier that exhibits a very low permeability to moisture and gases. This means that products coating in parylene generally are more “waterproof” than the same products coated in a liquid conformal coating.
  3. Solvent Protection. Parylene is unaffected by solvents, has low bulk permeability and is hydrophobic.
  4. Salt Protection. Coatings easily pass a 100hr salt-spray test due to the homogeneous coating.
  5. Parylene has excellent electrical properties. These include low dielectric constant and loss with good high-frequency properties, good dielectric strength, and high bulk and surface resistance.
  6. 100% Clarity. Parylene is transparent and can be used to coat optical elements.
  7. Room Temperature Deposition. Parylene is unique in being created directly on the surface at room temperature. Room temperature formation means the conformal coating and the parts are effectively stress-free.
  8. Inert in nature. Parylene is chemically and biologically inert and stable and make excellent barrier material.
  9. Excellent Penetration. Parylene coating completely penetrates spaces as narrow 0.01mm (10 microns)
  10. Good Thermal Properties. Parylene has good thermal endurance. Parylene C performs in air without significant loss of physical properties for 10 years at 80°C and in the absence of oxygen to temperatures in excess of 200°C.

Why Use Reusable Conformal Coating Masking Boots?

The use of other materials such as masking tapes, dots and liquid latex can be an effective process in protecting components from ingress of conformal coating.

Recyclable masking boots offer a labour saving alternative in both the masking and de-masking stages of the coating process.

This saves you time and money.
