Ceramic circuit board and Metal PCB are good in heat dissipation of PCB board.The application of the traditional LED heat dissipation substrate,Metal Core PCB (MCPCB) is different from the application range of ceramic heat dissipation substrate.MCPCB is mainly used in the system circuit board.The ceramic circuit board is applied to the LED chip
FR4 PCB is made of epoxy resin plus filler (Filler) and glass fiber, it has good insulation, corrosion resistance, compression, multilayer printing and so on.It is widely used in communication, automobile, medical, industrial control, security and other fields.The glass fiber board is divided into half glass fiber board and full glass fiber
LED lighting PCB is mainly based on aluminum substrate,The aluminum base circuit board is a unique metal based copper clad plate. It has good thermal conductivity, electrical insulation and machinability.
Characteristics of aluminum base circuit board:
Surface mounting technology (SMT)
The thermal diffusion is very effective in the design of the circuit.
LED lighting PCB is actual Aluminum core PCB, it’s a unique metal based copper clad laminate aluminum substrate. It has good thermal conductivity, electrical insulation performance and mechanical processing performance.
Features of MCPCB:
Adopt the surface mount technology (SMT);
Effective treatment of thermal dissipation in circuit design
Reduce the operating temperature of
LED brightness adjustable function is very important in LED lighting, but also the segment need to be great taked care in LED lamp and LED display.The following MCPCB manufacturers will analyze the principle of LED self dimming lighting system.
The technical principle of LED self regulating lighting system
The LED self dimming system is designed and developed according
