Metal Core PCB Construction

The metal core is positioned either in the middle or on the back side of the board relative to the copper layer. The metal core transfers heat to a metal heatsink backing. We use base metals as an alternative to CEM3 or FR4 substrates.

Core Thickness

Typically 30-125 mil, but we offer thinner or thicker metal cores depending on application requirements.

Copper Foil Weight

We offer copper foil of weight 1-10 oz for metal core PCBs to handle varying current requirements.

Advantages of Metal Core PCBs

Effective Thermal Management

Metal cores transfer heat 8-10 times faster than regular FR4 PCBs, keeping components cool and improving board performance.

Higher Mechanical Strength

Enhanced structural integrity at plated through holes (PTH) and connector points provides superior durability.

Improved Performance

Better heat dissipation results in significant improvement in board performance and extended service life.

Lower Thermal Resistance

High thermal conductivity dielectric polymer layer reduces thermal resistance for optimal heat transfer.

Metal Core Options

We use different metal cores for thermal PCBs, depending on the application. Our metal core PCB fabrication can handle various core materials with ease:

Aluminum
Most common, cost-effective with excellent thermal conductivity
Copper
Highest thermal conductivity for demanding applications
Special Alloys
Optimized thermal and mechanical properties for specific applications
Steel or Brass
Custom cores for specialized requirements

Design Considerations for Metal Core PCBs

Panel Design

Metal core PCB design is complex, as these PCBs are very hard and cutting them into smaller boards can be challenging. We prefer to design panels for metal core PCBs to make it easy to separate into smaller boards.

Special Chemicals

We use special chemicals during manufacturing that do not react with the metal core, ensuring the integrity of the thermal substrate throughout the fabrication process.
