Conformal Coating and Potting

Conformal coating and potting are two methods of enhancing or ensuring an assembly is protected in harsh environments and insulated against contamination. Conformal coating is the application of a protective chemical or polymer film that conforms to the PCBA’s topology. Potting is a process of filling an enclosure or mold with a compound that hardens to provide shock, vibration, moisture and corrosive protection to its enclosed electronics. Onlitex’s Contract Manufacturing Services experience includes 100’s of thousands of these ruggedized assemblies.
