Webinar: How to Avoid Errors in Conformal Coating Application

Why Discuss Conformal Coating Application

The application of conformal coating is a critical process to ensure the protection of printed circuit boards (PCB), especially in harsh environments where humidity, vibrations e contaminants can compromise the operation of electronic devices.

The conformal coating is designed to provide additional protection to PCBs, improving resistance to harsh environmental conditions and ensuring electrical insulation and reliability over time.

Not all devices require a protective coating, but for those exposed to extreme temperatures, chemicals, or mechanical stress, it becomes an essential necessity.

However, errors in conformal coating application can drastically reduce the benefits of protection, leading to premature failures and defects that are costly to correct.

It is important to consider that conformal coating cannot resolve pre-existing problems in design or manufacturing: if the PCB has defects, the conformal coating can amplify them. For this reason, it is essential to apply the conformal coating with precision, starting from an accurate analysis of the operating environment and material compatibility.

Topics covered in the webinar

The webinar will provide a clear overview of:

• the main errors in conformal coating application for PCB protection;
• the causes of the most common defects related to the process;
• the practical solutions to prevent problems such as corrosion, air bubbles, and adhesion defects;
• the importance of surface preparation.

During the webinar, some of the most frequent problems in applying conformal coatings to electronic boards will also be analyzed:

• corrosion: caused by contaminants and responsible for dendrite formation;
• air bubbles: due to air entrapment, viscosity, and non-optimized processes;
• orange peel: related to film irregularities and incorrect application;
• cobwebbing: due to excessively rapid drying of the conformal coating during spraying;
• dewetting and delamination: caused by contamination or incompatibility between materials.

It will also be shown how to prevent these defects through proper selection of process parameters, accurate surface preparation, and post-application quality control.

Who the webinar is for

The webinar is designed for designers, electronics engineers, production managers, and companies involved in electronic boards and technological devices.

It is particularly suitable for those operating in contexts where reliability of electronic protection is an essential requirement and where application errors can compromise the performance of the final product.
