• Thermal Conductivity up to 5.0 W/m·K
• Single-Sided, Double-Sided, and Selected Multilayer Structures
A medical metal core PCB uses aluminum or copper as a base instead of FR4. It draws intense heat away from critical electronic components. In multilayer configurations, the metal core balances heat dissipation across both sides of the board. By transferring thermal energy directly to a heatsink core, these boards prevent overheating and component failure. This advanced thermal stability is essential for high-power medical equipment, ensuring total operational reliability and long-term durability in life-critical devices.
Our production facilities operate under strict ISO 13485, ISO 9001, and IPC Class 2/3 medical standards. We maintain complete regulatory compliance to ensure every metal core PCB delivers the ultra-high reliability required for life-critical healthcare applications.
We support a broad range of high-performance metal bases, including aluminum and copper substrates. This flexibility allows us to tailor mechanical strength, weight, and thermal performance to your exact medical device specifications.
Our MCPCBs feature thermal conductivity ratings up to 5.0 W/m·K, bonding directly with internal metallic heatsinks. This high-efficiency heat transfer keeps sensitive electronics cool and prevents thermal degradation in high-power clinical devices.
With maximum panel size capabilities up to 1500mm x 600mm, we manufacture large-scale metal core circuit boards for complex diagnostic imaging systems, surgical lighting rigs, and heavy-duty medical power equipment.
By leveraging streamlined substrate processing and optimized manufacturing workflows, we deliver high-quality MCPCBs at highly competitive prices helping you achieve superior thermal performance within budget.
MedPCB provides thorough Design for Manufacturability (DFM) reviews to identify potential production issues early. We collaborate directly with your team to optimize trace routing, dielectric layer selection, and thermal vias to streamline production cycles, improve yield rates, and accelerate time to market.

Challenge: Metal core substrates like copper bases carry higher raw material costs and add significant physical weight compared to standard FR-4 boards, which can strain budget-conscious or lightweight device designs.
Our Solution: We have in-stock material selection for high-conductivity aluminum with optimized board geometries to deliver medical-grade heat management while keeping weight and production costs strictly controlled.
Challenge: Fabricating MCPCBs requires complex multi-stage laminations under extreme heat and pressure, as well as heavy-duty drilling through tough metal cores that wear down standard tooling.
Our Solution: Using specialized, carbide-tipped machining tools and automated lamination presses, we precisely drill and profile metal substrates without burrs, mechanical stress, or structural layer separation.
Challenge: Micro-voids or microscopic defects within the insulating dielectric layer disrupt thermal flow, creating localized hot spots that can destroy sensitive medical components or cause total board failure.
Our Solution: We utilize high-integrity thermal dielectric materials and perform automated optical and thermal-imaging inspections to ensure uniform heat transfer and avoid dielectric voids across every panel.
Challenge: Frequent power spikes and temperature swings cause uneven expansion between the metal base and surface components, risking solder joint fatigue, trace lifting, and eventual open circuits.
Our Solution: We'll help you choose suitable dielectric materials based on your project needs and control bonding and manufacturing parameters to improve thermal-cycle reliability.
MedPCB supports high-performance Metal Core PCB (MCPCB) materials designed for high thermal conductivity, superior heat dissipation, and long-term reliability in critical medical devices.
Aluminum Core PCB – Aluminum is the most popular metal core material, offering excellent thermal dissipation, high strength, and cost-efficiency. It works well for medical equipment requiring reliable cooling, such as high-power LED lighting, power supplies, and surgical lamps.
Copper Core PCB – Due to its superior thermal conductivity over aluminum, copper excels in demanding thermal environments. It can be considered for high-power medical electronics such as laser systems and imaging equipment where efficient heat dissipation is required.
MedPCB supports metal core board fabrication based on your thermal management needs, component density, and device size. Send your files to us so we can review your design through a free DFM check for reliable medical PCB production.
High-output, multi-head LED systems use aluminum substrates to transfer heat away from LEDs during long surgical procedures. Efficient heat dissipation helps maintain consistent brightness and reduces LED temperature buildup.
Lightweight headlamps benefit from aluminum substrates because they support efficient thermal management in a compact PCB design. Better heat transfer helps prevent excessive surface temperatures near the surgeon and patient.
These systems use high-intensity blue LEDs that may operate for extended periods. Aluminum substrates help dissipate LED heat efficiently, supporting stable light output and reliable operation.
Aluminum substrates help manage heat in compact, high-CRI dental lighting systems. Efficient thermal transfer reduces heat accumulation around the LEDs while helping maintain consistent illumination during procedures.
