What a liquid coating service covers

A coating is only as good as the preparation and the masking around it. We handle the whole sequence, so connectors, test points and other areas stay clear and the rest of the assembly is protected.

Cleaning

Boards are cleaned before coating, because residue left under a coating can cause failures later.

Masking

Connectors, switches, test points and other areas that must stay clear are masked before coating.

Coating

We apply the coating you specify, such as acrylic, silicone, urethane or epoxy, by spray, dip, hand or gel.

De-masking

Masking is removed carefully so the finished assembly is ready for the next process.

Inspection

Each job is inspected after coating for coverage and defects.

Certificate of conformity

A certificate of conformity is available if your order requires one.

From enquiry to coated assembly

A liquid coating job follows the same order each time.

Send the assembly details, the coating specification, the quantity and the areas that must stay uncoated.

We confirm the method (spray, dip, hand or gel) and send a quote.

The assembly is cleaned and masked.

The coating is applied to your specification.

Masking is removed, the job is inspected and a certificate of conformity is issued if required.

Liquid conformal coating questions

Short answers to what buyers usually ask first.

Which conformal coating type should I choose?

IPC standards group coatings by chemistry: acrylic (AR), epoxy (ER), silicone (SR), polyurethane (UR) and parylene (XY). Each trades off protection, flexibility and ease of repair. Acrylics are generally the easiest to remove for rework and epoxies the hardest. Your product specification or operating environment usually decides, so tell us either and we will advise.

What is the difference between spray, dip, hand and gel application?

Spray and dip are typically used to coat whole boards, and hand application suits small batches, touch-up and localised areas. We will recommend the method, including gel where it suits, for your assembly and quantity.

Can you mask connectors and test points?

Yes. Tell us which areas must stay uncoated and we will mask them before coating and remove the masking afterwards.

Can you coat after programming?

Yes. The usual order is to programme and test first, then mask programming points and coat.

Do I need plasma cleaning first?

Sometimes, when a material is hard to coat. See our plasma cleaning page, or ask us if you are unsure.

Need boards coated?

Send us the assembly details, the coating specification and the quantity, and we will confirm the method and a quote.
