Metal Core PCB: A Comprehensive Guide for Buyers in 2025


Metal Core PCBs (MCPCBs) are widely used in high-power and high-heat applications due to their excellent thermal conductivity and durability. Whether you're in the LED industry, automotive sector, or power electronics, understanding Metal Core PCB technology is crucial for optimal performance. This guide covers everything you need to know before purchasing MCPCBs, especially from Chinese manufacturers.


How to Find Reliable Metal Core PCB from China in 2025


China is a leading supplier of Metal Core PCB, offering competitive prices and advanced manufacturing capabilities. To find reliable suppliers, consider the following:

  • Check certifications like ISO 9001 and UL listings.
  • Review customer feedback and case studies.
  • Request samples to evaluate quality.
  • Verify production capacity and lead times.

What Buyers Should Know Before Buying Metal Core PCB from China


Purchasing Metal Core PCB from China requires due diligence. Ensure the supplier provides detailed specifications, including thermal conductivity, dielectric thickness, and copper weight. Negotiate MOQs (Minimum Order Quantities) and confirm shipping terms to avoid hidden costs.


Types of Metal Core PCB


There are three main types of MCPCBs:

  1. Single-layer MCPCB: Ideal for simple designs with high thermal needs.
  2. Double-layer MCPCB: Offers better circuit complexity.
  3. Multi-layer MCPCB: Used for advanced applications requiring multiple signal layers.

Functions and features of Metal Core PCB


Metal Core PCB excels in heat dissipation, making them perfect for LED lighting, power converters, and automotive systems. Key features include:

  • High thermal conductivity (up to 10W/m.K).
  • Improved mechanical strength.
  • Longer lifespan compared to FR4 PCBs.

Scenarios of Metal Core PCB


MCPCBs are used in:

  • LED lighting (streetlights, automotive LEDs).
  • Power supplies and inverters.
  • Industrial motor controls.
  • Solar power systems.

How to Choose Metal Core PCB


Selecting the right Metal Core PCB depends on:

  • Thermal requirements: Higher conductivity for high-power applications.
  • Layer count: More layers for complex circuits.
  • Material: Aluminum (most common) or copper for extreme heat.
