The base material of LED PCB board often uses aluminum base, because aluminum substrate has good thermal conductivity, electrical insulation, and machinability. Some LED PCB boards also use copper-based materials, FR4 materials. Light bar LED PCB board will also be used to make flexible board PI material.
The specific use of what materials, mainly depends on the comprehensive consideration of the lamp manufacturer. Based on low cost and other comprehensive considerations, some customers will choose CEM3 material.
Here we recommend one of the CEM3 materials used by OPCBA: KB-7150T.
(1) Its applications.
●LED backlight

●Car display lamp
●Instrument panel
●DC-AC etc
(2)Its features.
●High thermal conductivity
●High CTI value
●Excellent heat resistance
Low Z-axis expansion
Low moisture absorption
●Excellent Anti CAF performance
●IPC-4101E/81 specification is applicable
