“What is Micro Coating?”
Micro coating is a process in which durable coatings are selectively applied to small areas on an electronic assembly that require protection from elements in their operating environment, which commonly include moisture and liquids. Micro coating was first adopted by consumer devices to reduce device thickness. It is now beginning to catch on in other markets including aerospace and automotive. Micro coating applications are often very similar to encapsulation, but the materials are typically applied over the surface of leads with a high-accuracy automated application system. Many of DYMAX’s conformal coatings and encapsulation materials can be used as micro coatings.
