Which coating service does your assembly need?

Coating protects electronics from moisture, dust, chemicals and contamination. The right choice depends on the assembly, the environment and the specification you work to, so we start by asking what has to be protected and what has to stay uncoated.

Liquid conformal coating

Cleaning, masking, coating, de-masking and inspection, applied by spray, dip, hand or gel to the coating you specify.

Parylene coating

A thin, uniform coating formed from vapour with no liquid phase, for assemblies and components that need an even barrier.

Plasma cleaning

Surface treatment before coating, for materials that are hard to coat with conventional cleaning alone.

Masking and de-masking

Connectors, test points and programming headers are masked before coating, and the masking is removed afterwards.

Inspection and certification

Inspection after coating, with a certificate of conformity if you require one.

One supplier for the next step

Programming, testing, dry packing and tape and reel are available from the same supplier, so you manage one relationship for the whole route.

How a coating job works

Five steps from your enquiry to coated product.

Tell us what you are coating, the coating type or specification, the quantity and any areas that must stay uncoated.

We confirm the process, advise on the coating if you are unsure, and send a quote.

Parts are cleaned and masked, with plasma treatment first where the material needs it, and then coated.

Masking is removed and each job is inspected, with a certificate of conformity if required.

Coated product goes back to you, or on to programming, testing, dry packing or tape and reel.

Conformal coating questions

Short answers to what buyers usually ask first.

What is conformal coating?

A thin protective layer applied to a circuit board or component so it resists moisture, dust, chemicals and contamination. It follows the shape of the assembly, which is why it is called conformal.

Should I choose liquid conformal coating or parylene?

Liquid coatings are applied by spray, dip, hand or gel and suit most circuit boards. Parylene forms from vapour at room temperature, so it coats edges and tight gaps in a thin, even layer without runs or pooling. Because parylene resists solvents, it is harder to strip for rework than most liquid coatings. Tell us the operating environment and your specification and we will advise on which fits.

Do I need plasma cleaning before coating?

Not always. Plasma treatment helps with materials that coatings struggle to stick to using conventional cleaning alone. If you are unsure, send us the material and the coating you plan to use.

Can you coat parts after programming?

Yes. The usual order is to programme and test first, then mask any programming points and coat. We can advise on the order for your product.

What needs masking before conformal coating?

Anything that must stay uncoated, typically connectors, switches, test points and programming headers. Tell us the keep-out areas when you ask for a quote and we will mask them before coating and remove the masking afterwards.

What do you need to give a quote?

A description of the assembly or part, the coating type or specification, the quantity, any areas that must stay uncoated, and whether you need a certificate of conformity.

Need something coated?

Send us the assembly or part, the coating specification and the quantity, and we will confirm the process and a quote.
