What is a metal PCB?
Metal PCB, the full name of Metal Core Printed Circuit Board, is a printed circuit board that uses metal as the substrate material. Compared with traditional fiberglass substrates, metal PCBs are gradually emerging in the electronics industry. Its main advantage over traditional substrates is its excellent heat dissipation performance and mechanical strength, making it the first choice for electronic devices with high heat dissipation requirements.
First, let’s understand what a metal PCB is made of. Metal PCB usually consists of three main parts: metal substrate, dielectric layer and copper foil layer. The metal substrate is the core of the metal PCB. It carries the structure of the entire circuit board and provides the main path for heat dissipation. Commonly used metal substrate materials include aluminum, copper and aluminum-based composite materials, which have excellent thermal conductivity and mechanical strength and are suitable for the manufacture of various high-performance electronic devices.
Compared with traditional fiberglass substrates, metal PCBs have higher heat dissipation efficiency and better mechanical stability. This is due to the excellent thermal conductivity of metal substrate materials, which can effectively conduct the heat generated by electronic components to the environment quickly. Especially in application scenarios with high heat dissipation requirements, such as LED lighting, automotive electronics and power modules, metal PCBs have shown unparalleled advantages.
In addition to thermal performance and mechanical strength, metal PCBs offer other advantages. For example, metal PCB has excellent electromagnetic shielding performance, which can effectively reduce electromagnetic interference and improve the stability and reliability of the circuit. In addition, the processing technology of metal PCB is relatively simple, which can achieve high-density wiring and multi-layer structure to meet the needs of complex circuit design.
In general, metal PCBs are widely used in the electronics industry for their excellent heat dissipation performance, mechanical strength and electromagnetic shielding performance. With the continuous advancement of technology and the continuous demand of the market, metal PCB will continue to play an important role in promoting the innovation and development of electronic products.

Reasonable size design can effectively improve the heat dissipation performance of the circuit board and ensure that it is not easily deformed or damaged during use. When determining size, factors such as space constraints where the circuit board will be located, thermal needs, and mechanical assembly requirements need to be considered.
Cabling design
Good wiring design can minimize signal interference and power loss and improve the performance and stability of the circuit board. When designing a metal PCB, care needs to be taken to avoid too dense wiring or too long traces to reduce wire resistance and signal delay. In addition, circuit components and connectors need to be arranged appropriately to facilitate heat dissipation and maintenance.
Thermal design
Metal PCBs have good heat dissipation properties, but in some high-power applications, additional heat dissipation design is still required. Reasonable heat dissipation design can effectively reduce the operating temperature of the circuit board and extend its service life. Common heat dissipation design methods include adding heat sinks, using heat dissipation glue, and designing heat dissipation channels.
Environmental adaptability
When designing a metal PCB, it is necessary to consider the environmental conditions in which the circuit board is located to ensure that it can adapt to various harsh working environments. For example, in high temperature or humid environments, waterproof and dustproof design measures are required to protect the normal operation of the circuit board. In addition, factors such as electromagnetic compatibility (EMC) and electromagnetic interference (EMI) need to be considered to ensure that the circuit board is not subject to external interference.
Designing a metal PCB is a complex and important task that requires the consideration of multiple factors.
