What Is an IMS PCB?
An IMS PCB is a circuit board constructed on a metal plate—typically aluminum—covered by a specialized thermal prepreg layer. This dielectric layer provides excellent heat-conducting properties while maintaining high dielectric strength to withstand elevated voltages. Because of this design, IMS boards are ideal for high-energy or high-thermal-load environments, such as modern lighting systems featuring high-intensity LEDs.
Superior Heat Dissipation Capabilities
The key advantage of IMS PCBs lies in their thermal performance. Compared with a standard 1.60 mm FR4 PCB, an IMS board with a 0.15 mm thermal prepreg can offer thermal resistance that is over 100 times lower. This enables efficient heat transfer away from components, dramatically improving reliability and extending the lifespan of electronic assemblies.
