When electronics are required to be exposed to harsh conditions, Sure-Fi can add the Conformal Coating protection necessary for normal function.
Conformal coating may be beneficial in more than just harsh conditions. When the coating is applied to boards in typical operating environments, it is still protecting the board's components from humidity, dust, and a myriad of unseen antagonists.
You may also be required by a customer or regulating body to ensure that you apply the conformal coating to specific standards, given your application.
Applying conformal coating will surely increase the longevity of your PCBA and, therefore, your products and customer satisfaction.
