Metal Clad PCB Power Efficiency | Metal Core PCB
Printed circuit board has a special part called Metal Clad PCB. There are several reasons why custom MCPCB is ideal for led industry. The first and foremost is that PCB specifications include an ability to integrate dielectric polymer layer. Moreover, this provides significantly higher thermal conductivity.
Here is a story when I came across MCPCB. A normal day as usual I was preparing a circuit that protects Thruster from high voltage. After completing my circuit construction virtually, I made a prototype with manual calculations because it works most of the time.
After testing I was glad with my co-workers. But the next day I realized that there were too much AMPS and FR4, it will go on fire immediately. And that’s where I started doing intensive research about finding a solution to stop the high heat. Finally I found a type of metal called MCPCB.
We can use this high powered LEDs in motor cars for example.
MCPCB has different names
- Aluminum clod
- Aluminum base
- Thermally conductive PCBs
This element also has different metals such as Flexible Aluminum and others.
What’s inside MCPCB?
MCPCB is made up of thermal insulating layers, metal plates, and metal copper foil.
In the end the advantages are that these boards posses the ability to integrate a dielectric polymer layer with HIGH THERMAL CONDUCTIVITY.
The manufacturing Metal Clad PCB, the circuit of the layer is bonded thermally with a dielectric material.
This layer is further build with a thin body of metal which can be made of Aluminum 5052 (5052H32), Aluminum 6061 (6061T6) or Copper C110. This thick metal measures 1 mm, 1.5 mm, and 3.2 mm, and it’s already sufficient to provide the quality in the moment of use.
Most known the thermal conductive PREP-REG, it’s a layer that transfers the heat into another layer.
The advantages of using PCBs with a two-layer metal core are many. Some of the main benefits include:
- Longer component life
- High heat dissipation
- Good dimensional stability
- High power density
Other advantages of aluminum coating include:
- Lower operating temperature.
- Reduce the size of the printed circuit board.
- Increase power density.
- Extends the life of the matrices.
- Reduce the number of interconnections.
- It improves the thermal and mechanical performance of the product.
- Combine power and control.
- It improves the durability of the product.
- Enable better use of surface mount technology.
- Expedite heat-sinks and other mounting components.
- Replace delicate ceramic substrates with longer mechanical durabilityFinally, multi-layer circuits allow the creation of very complex circuits, with the further advantage of being able to mount components with many pins, such as integrated circuits, very close to each other, to the benefit of miniaturization.
