Conformal coating is designed to protect against humidity, condensation, and occasional splashes. For devices that must survive underwater or high-pressure washing (IP67\/IP68), Potting (Encapsulation) is the superior choice.<\/span><\/p>\n<p><span style=\"font-weight: 400;\"><strong><span style=\"color: #000080;\">Q:<\/span><\/strong> Does potting cause electronics to overheat?<\/span><\/p>\n<p><span style=\"font-weight: 400;\"><span style=\"color: #000080;\"><strong>A:<\/strong><\/span> It can if the wrong compound is used. While potting restricts airflow, thermally conductive epoxies can actually help dissipate heat by moving it away from hot components to the housing case. Fenix engineers assist in selecting the right thermal compounds for your specific heat profile.<\/span><\/p>\n<p><span style=\"font-weight: 400;\"><strong><span style=\"color: #000080;\">Q:<\/span><\/strong> Why is adhesion important for conformal coating?<\/span><\/p>\n<p><span style=\"font-weight: 400;\"><strong><span style=\"color: #000080;\">A:<\/span><\/strong> If the coating does not stick effectively to the board, moisture can pool underneath it (delamination), causing corrosion faster than if there were no coating at all.
