Q: Of all the various conformal coating materials available, what would you recommend for automotive electronics?
A: The question indicates knowledge that there are different conformal coating options out there. It is not really possible to pick a definitive solution without knowing more detail about the application specifics. In general, a conformal coating is used to seal the electronics from the environment, but there may be other demands/desires placed on the material in terms of “reworkability” and/or special environmental and/or chemical resistance requirements. I’d suggest creating a list of desired qualities and performance needs/requirements, along with ease of use, reworkability, and submitting them to the various vendors for their responses. The vendors can often serve as good and reliable resources for answering questions you might not have thought to ask.

Let’s face it, in the past, electronics manufacturing has not been a big business for North America. A majority of electronics are assembled in Asia where supply chains and operating costs offer many economic advantages. In North America, the electronics manufacturing industry has been generally focused on lower volume, high-cost devices, while higher volume products are produced elsewhere. However, the COVID pandemic and various legislation in the U.S. are changing the situation, making electronics manufacturing in North America a more attractive option. How can factories in North America compete for the same type of manufacturing traditionally performed in lower-cost regions?
