Electrolube’s Phil Kinner discusses the evolution of tougher, more environmentally friendly conformal coating materials that have been formulated to cope reliably with the rigours of modern electronics deployments.
Modern electronic assemblies are increasingly expected to survive hostile operating environments and work reliably in conditions of prolonged high temperatures in the presence of thermal shock and high humidity, and where the assembly may be subject to condensation, corrosive agents or other types of chemical attack. Despite this, weight-saving measures have reduced the robustness – and therefore the protective properties – of enclosures and at the same time, environmental legislation continues to limit the use of those considerably more versatile solvent-based protective materials.
