A metal core PCB or MCPCB is a type of PCB that has a metal layer on the surface of the board. This layer can be made from copper or nickel. The metal layer provides a number of benefits to the board such as improving the signal quality and reducing electromagnetic interference (EMI).
The metal layer is typically located in the center of the board and surrounded by two layers of dielectric material. It acts as an electrical shield, which prevents unwanted electrical signals between circuits on opposite sides of the board from interfering with each other. This allows for greater flexibility when designing circuits for high-frequency applications, such as wireless communications devices, because it prevents crosstalk between different signal paths within individual chips.
The MCPCB can also be used to make connections between different layers, which is known as through-hole technology (THT). In this case, there are holes drilled in each layer where they meet at right angles so that wires can pass through them.
Application of metal core PCB
They are used in a variety of applications where high amounts of heat are generated and need to be dissipated, including:
- Power supplies
- LED lighting systems
- Power conversion systems
- Industrial motor controls
- Electric motor drives
- Aerospace and military applications
Two types of MCPCBs
It has two types: single sided and double sided metal core PCBs. Single sided metal core PCBs only have one layer of copper foil on both sides while dual-sided metal core PCBs have two layers of copper foil on both sides. The thickness of single-sided metal core PCBs ranges from 0.15mm to 0.35mm while the thickness of double-sided metal core PCBs ranges from 0.2mm to 0.5mm according to different requirements from customers.
Benefits offered by MCPCBs
Metal core PCBs are now a standard in the industry. They are used for different applications such as industrial control systems, medical devices and many others. Because of their high quality and reliability, they have become very popular in recent years.
The use of metal core PCBs has been increasing steadily over the years. This is because they offer various advantages when compared to other types of printed circuit boards (PCBs). These include:
*High reliability: The metal layers on these boards are thicker than those on other types of PCBs. They are also more durable as compared to plastic ones. This makes them more reliable when it comes to handling harsh environments or high loads.
*Greater design flexibility: Metal layers allow for more complex designs than plastic ones do. This means that you can run your circuit board through many different tests without worrying about it breaking down or becoming unusable afterward.
*High conductivity: The conductivity offered by metal layers is much higher than that offered by plastic ones. This means that you won’t have to worry about any short circuits or electrical interference when using these boards in your project.
Choosing the right company
The choice of a metal core PCB manufacturer is an important one. There are several factors to consider when choosing the right supplier. The most important factors include:
- Quality of the boards
- Cost of manufacturing
- Delivery time and quality control
- Customer service and after-sales support
