Metal Core PCB
Metal core PCB is thermal management circuit board used in LED lighting which needs fast
Cooling dissipation. the metal core can be aluminum (aluminum core PCB) and copper
(copper core PCB), stainless steel, even iron base. 

Advantages of MCPCB
1) Effective heat dissipation reduces the operating temperature of the module and prolongs
the service life;
2) Power density and reliability are improved up 10%;
3) Reduce the dependence of heat sinks and other hardware (including thermal interface
Materials);
4) Reduce the volume of the product;
5) Reduce the cost of hardware and assembly;
6) Optimization combination of power circuit and control circuit;
7) Replace the fragile ceramic substrate and obtain a better mechanical durability;
8) Reduce the operating temperature of the equipment.

Applications
LED lighting, Switch regulator, DC/AC converter, Communication electronic equipment,
A filter electric circuit, Office automation equipment, Motor driver,  Motor controller,
Automobile etc.

Solder Mask
Depending on whether light is to be absorbed or reflected, we have green, black and white
Solder mask. White solder mask is commonly used in LED PCB application and we use super
White LED solder mask and no yellowish or brown colour occurs after the bare PCB baking
as well as reflow and wave solder PCB assembly processes.



MCPCB Case: Aluminum PCB with Bowl-Dented Hole
for LED Lighting
(PCB's are custom-made products, the picture and parameters shown are just for reference)


General description
this is a type of single sided aluminum PCB for the application of LED Lighting with bowl
-dented holes. It's at 1.6 mm thick with 1 W/MK thermal conductivity. The aluminum plate
Is from ITEQ, Solder mask and silkscreen from Taiyo. It's fabricated per IPC 6012 Class 2
Using supplied Gerber data. 25 boards are packed for shipment.
