What is a metal core printed circuit board (MCPCB)?

Metal core printed circuit boards are a special type of PCB that uses a metal substrate as its base material, unlike the FR4 material commonly used in general PCBs. Copper-core PCBs typically use aluminum, copper, or other alloys as the core material.

Q1. How much better is the thermal performance of your metal core PCB than FR4 ?

KING FIELD: Our metal core PCBs conduct heat 8 to 10 times faster than standard FR4 .

Q2. Are all your metal core PCBs single-layered?

KING FIELD: Of course not. While most metal-core PCBs are single-layered , double-sided and multi-layer metal-core PCBs also exist. Furthermore, we can produce thermoelectrically separated metal-core PCBs.

Q3. What is the typical stack-up structure of your metal core PCB?

KING FIELD: A typical metal-clad PCB consists of the following three parts:

• The metal substrate can be aluminum, copper, iron, etc.
• Dielectric layer used for electrical isolation;
• Copper circuits that enable electronic functions.

Q4. What is the difference between a metal core PCB and an FR4 PCB?

KING FIELD: Although both metal-clad PCBs and FR4 PCBs are rigid PCBs and widely used, they differ in several ways, the main differences being as follows:

• The materials used differ: metal-based PCBs use alloys such as aluminum and copper as the core material, while FR4 PCBs only use glass fiber.
• Different uses: Metal-clad PCBs are often used in applications requiring heat dissipation, such as high-power PCBs and LED PCBs; while FR4 PCBs are widely used in most electronic devices.

Q5. What is the thermal conductivity of your metal core PCB?

KING FIELD: The thermal conductivity of metal core PCBs ranges from 1 W/m·K to 400 W/m·K, depending on the material parameters.
