Potting, Protection & Thermal Management for LED Drivers
LED drivers are critical electronic assemblies responsible for regulating power supplied to LED systems. Their components can require protection from humidity, dust, vibration, thermal cycling and electrical stress.
Potting and encapsulation materials help create a protective barrier around PCBs and electronic components while providing mechanical stability, electrical insulation and environmental protection.
Thermal-management materials can additionally support heat transfer away from heat-generating electronic components and help maintain stable operating temperatures.
