Conformal Coating & Potting

We are a full functional Contract Manufacturer. We can provide Potting and Conformal Coating of part or all of your assembly. We commonly use acrylics, epoxies and urethane compounds to seal and protect sensitive assemblies.

We offer spray coating, potting, fluid bed coating, brush coating or dip coating. PCB conformal coating material and potting material is applied to electronic circuitry to act as protection against moisture,dust, chemicals, and temperature extremes that if uncoated (un-protected) could result in a complete failure of the electronic system.

Selection of the correct choice of coating and potting material is one of the most critical decisions. Criteria for selection must be based on answering many questions, which will include:

• What is the assembly being protected against? (e.g., moisture, chemicals)
• What temperature range will the electrical device encounter?
• What are the physical, electrical, and chemical requirements for the coating material itself?
• What is the electrical, chemical, and mechanical compatibility with the parts and substances to be coated?

Answers will be determined by the suitability of a particular material, be it acrylic, polyurethane, silicone, epoxy, transparent, fully covering, etc. Process, production and commercial issues will then enter the equation:

• How easily can the material be reworked once applied?
• How fast does the material dry (cure)?
• How rigid or flexible is the material?
• What type of process and equipment is necessary to achieve the required coating quality (uniformity and repeatability)?
• Price of the material.
• Quality of the material

We can help determine the proper coating for your application.
