Conformal Coating Types

Brush coating is done by hand and.

Conformal coating types. Popular types of pcb conformal coating include. Types of conformal coating. The provider must be comfortable handling requests and questions about all five types. Selecting the proper conformal coating type requires a knowledge in not only conformal coatings but the specific assemblies and environments they will reside in.

With that in mind let s go over some of the types of conformal coating at your disposal. There are a number of options for coating technologies and the best option should depend mainly on the protection required. There are many different facets to conformal coating from equipment and applications to the different types of coatings. A simple application method this is best for low volume production rework and repair.

Coatings can be applied in a number of ways including brushing spraying. Typically applied at 25 250 μm micrometers thickness it is applied to electronic circuitry to protect against moisture dust chemicals and temperature extremes. Here are the six most common causes of conformal coating defects we see along with recommendations for how to avoid them. Summit technologies has over 30 years of professional experience with conformal coatings and will work closely with you to select the proper type of coating for your project should you need.

Conformal coating material is a thin polymeric film which conforms to the contours of a printed circuit board to protect the board s components. Below are descriptions pros and cons of each. Conformal coating is a protective non conductive dielectric layer that is applied onto the printed circuit board assembly to protect the electronic assembly from damage due to contamination salt spray moisture fungus dust and corrosion caused by harsh or extreme. Urethane resin ur epoxy resin er acrylic resin ar silicone resin sr and parylene xy.

It outlines typical properties of each coating type and how they impact performance considering the intended end use. While many varieties of coating exist including a few specialty types there are five main categories based on the substances chemical makeup. It also outlines processing steps to assure proper coating application. Ipc hdbk 830 was designed to assist in the selection of a conformal coating.

Capillary flow is a type of coating migration that happens when a liquid conformal coating pulls away or flows from one area of the substrate to another. Automotive commercial defense industrial and medical applications conformal coatings are applied in film layers generally 30 130 microns micrometers μm thick or 0 0012 0 0051 inches conformal films exceptional thinness is their greatest asset.
