Conformal Coatings Vs Potting Compounds Which is better to protect my PCB, a coating or a resin?

Tags: Encapsulation Resins, Conformal Coatings, 2K Range

This is a question that is often asked throughout the electronics industry and Like any good engineering answer, it depends… on the degree of environmental protection required. The first thing to consider is often the design of any housing within which the PCB will be enclosed. If an assembly is enclosed in a housing which is designed to be the primary environmental protection, then a conformal coating is often used to provide a back-up to the primary protection provided by the housing. Where the housing is not suitable or capable of providing primary protection of the assembly from its operating environment, then most times a resin might be a better choice. Read more >

Conformal coatings are expected to perform across all manner of environments including high humidity environments, typically 40°C/93% RH, 65°C/95% RH or 85°C and 85% RH. Until recently, there has been little attention paid to how conformal coatings and their characteristics perform under such condensing conditions. Testing has previously been confined to humidity chambers which have certain limitations in respect to this testing type. Read more >

How conformal coatings help automotive manufacturers achieve long-term reliability of assemblies

In a typical car today, electronic systems are critical to the smooth and safe operation of the vehicle. Even before the engine starts, electronics have already unlocked the car. Once you start the engine and step on the accelerator, sensors assist in getting out of your parking space, engine control units (ECUs) tune the engine performance, monitor the pressure of the tyres and safety systems are powered up in standby mode. As you pull away, adjust the air conditioning, ensure your phone is connected to the entertainment system, set your destination on the satellite navigation system and initiate your favourite music, yet more electronic systems are brought to life...
