Excello Circuits, a provider of PCB manufacturing services for applications requiring thermal performance, reliability, and specialized PCB technologies, offers Metal Core Printed Circuit Boards (MCPCBs), a PCB technology that incorporates a metal base material to improve heat dissipation in electronic assemblies. Also referred to as thermal PCBs or metal-backed PCBs, these boards use aluminum or copper cores positioned on one side of the PCB or within the board structure.

Thermal Management Through Metal Core Construction

The company’s MCPCBs are designed to transfer heat away from critical components to less sensitive areas, including metal heatsink backings or the metallic core itself. This construction supports thermal management requirements in applications where conventional FR4 or CEM3 boards may not provide sufficient heat dissipation.

Manufacturing Capabilities

Excello Circuits manufactures MCPCBs with the following capabilities:

• Single-sided to multi-layer board configurations
• Aluminum and copper plate constructions
• FR-4, PTFE, and thermal dielectric materials
• Dielectric thicknesses from 0.05 mm to 0.20 mm
• Thermal conductivity ranging from 1 W/mK to 12 W/mK
• Punching and liquid-cooled routing profile methods
• Copper weights from 0.5 oz to 4 oz on inner layers and 1 oz to 20 oz on outer layers
• Trace and space capabilities down to 0.003 inch
• Metal core thicknesses from 0.40 mm to 3.20 mm

Surface Finish Options

The company provides multiple surface finish options for metal core PCB production, including HASL, Lead-Free HASL, OSP, ENIG, Immersion Tin and Immersion Silver.

Application Areas

Excello Circuits states that its metal core PCB manufacturing capabilities support applications in:

• Automotive systems
• Telecommunications equipment
• Consumer electronics

The company’s MCPCB offering combines metal-core construction, thermal management materials, and multi-layer manufacturing capabilities for electronic products requiring efficient heat dissipation and long-term operational reliability.
