Purpose and goal

The goal of the project was to develop new insights and solutions for barriers and design methods against high humidity, corrosion and extreme temperatures for electronic modules and systems. These goals were achieved by specific studies of state of the art protective conformal coating, corrosion standards, modelling methods with examples and specific high temperature design issues.

Results and expected effects

Effectiveness of conformal coatings on PCB was investigated. Contamination level, parallel impedance sensitivity and metal layer spacing are the main parameters. The most used corrosion standards for electronics are summarized with examples. With modelling we can obtain electromagnetic characteristics, parasitics and various couplings and dependence of temperature, pressure, humidity. A modelling example was given. The temperature performance of DC bus capacitors was analyzed. We describe current technologies, new materials and design methods for DC bus capacitors.

Approach and implementation

The project was executed in cooperation between four industrial partners and three research partners. In the execution we focused on identifying the most relevant environmental issues for the participating industries through visits and specific discussions. From these we concluded the main focus areas of the project. By this way of execution we achieved an important exchange of knowledge between research partners and industry and produced relevant results for the industry.
