Masking materials and Thin Film Partners

Masking boots, tapes and dots are essential for processing thin film materials that do not selectively coat the surface of a component or circuit.

The coatings that require masking materials in the production process included Parylene, conformal coatings and other thin film technologies applied with techniques such as Atomic Layer Deposition (ALD) and Molecular Vapour Deposition (MVD).

Our masking materials are designed for thin film processing.

Range of Services

Thin Film Partners LLC offers a range of masking materials for conformal coating, Parylene and ALD processing.

These masking materials include:

These masking materials meet the highest standards required for both liquid conformal coatings and Parylene production processing.

They are also extremely price competitive.

Reusable masking boots

Our masking boots are recyclable and reusable.

They can form an integral part of a full masking solution in coating applications for printed circuit boards. This is for both liquid conformal coating process or a vapour deposition process such as parylene.

Our masking boots provide protection for many different types of components for all conformal coating application techniques.

We can provide both standard and custom boots solutions for a customer depending on their needs.

We can provide quotations and suggestions for how to optimise your masking process.

Conformal coating masking tapes

Thin Film Partners offer two types of conformal coating masking tape which compliment each other in the process.

The first tape is used for masking components like connectors on the printed circuit board. The second type is used for masking grounding planes and flat sections such as edges of PCBs.

Conformal coating masking dots

Our range of conformal coating masking dots are compatible with all types of conformal coatings including solvent based acrylic, silicone, polyurethane and epoxy materials plus all of the solvent less conformal coatings.

The Conformal coating masking dots sizes include 4.8mm, 6.4mm, 7.9mm, 9.5mm, 12.7mm & 19mm as standard.

Why use masking materials in the production process?

Normally, there are areas on the product that must not be coated. Materials like conformal coatings and Parylene are insulative when dry so will cause problems on components like connector contacts.

Since the coating process tends to be invasive if it is non slective then you have to protect the parts that must not be coated. So, you use masking materials like custom reusable boots, tapes and dots.

Why have different masking materials for processing?

Our extensive range of masking products includes tapes, dots and masking boots.

This is because there are several variables involved including the volume of production, the type of coating being applied and the complex geometry of the circuit board or part to be masked.

Masking tapes tend to be used for masking low volumes of components on the product. If there are higher volumes then it can be more cost effective to use reusable masking boots. Tapes also work on flat areas that need protecting such as edges of circuit boards or conductive pads.

The masking dots tend to be used to protect areas like mounting holes. Conductivity needs to be maintained and a simple dot can solve the problem.

Finally, masking boots are used where a certain volume of repeat masking is reached. These reusable plugs or shapes cover the whole area very quickly and are highly effective. Typically, the return on investment is very quick compared to tape and dots.
