Learn More About Polyurethane

Polyurethane coatings are amongst one of the most popular choices for conformal coating applications, they are available as single component, two component, UV curable, and water borne systems. As a group, all provide excellent humidity and chemical resistance plus outstanding dielectric properties for extended periods; which make them one of the more popular coatings when it comes to protection of the critical operation of your printed circuit boards (PCBs).

Polyurethane Coating Solutions

Conformal coating circuit boards reduces conductor spacing’s on PCBs and it will offer superior protection in an aggressive environment as well as protecting the PCB against environmental particulates.

Why Polyurethane?

A main reason conformal coatings are used are to extend the warranties on consumer electronics in the following fields automotive, control drives, fire alarms as well as military/aerospace safety features and long term reliability. The selection of conformal coating material is a crucial factor that needs to be considered carefully and in relation to the application method. The wrong selection can not only affect the long term reliability of the circuit board but can cause massive difficulties with both processing and costs.

The most common standards for conformal coating are IPC A-610 and IPC-CC-830. These standards list indications of good and bad coverage and describe various failure mechanisms such as de-wetting and orange peel. Conformal coating inspection is a critical factor in determining successful coating application and long term reliability of PCBs. Using the IPC standards allows the coating operator to monitor the coating application performance. This can be done manually by the operator in an inspection booth by examining the PCB under white and UVA light or it can be done automatically by a conformal coating inspection system.
