What Is MCPCB Fabrication?
MCPCB fabrication involves manufacturing circuit boards with a metal core (typically aluminum or copper) to enhance heat dissipation. The process includes bonding a thermally conductive dielectric layer to the metal base for electrical insulation, laminating a copper circuit layer on top, and etching circuit patterns via photolithography. Vias are drilled and plated for electrical connectivity, followed by surface finishes to protect copper and ensure solderability. Designed for high-power applications, MCPCBs efficiently manage thermal stress in devices like LEDs, automotive systems, and power electronics.

Benefits of Metal Core PCB Fabrication
- Superior Heat Dissipation – Metal cores (Al/Cu) conduct heat 8–12× faster than FR4, reducing component temperatures by up to 15°C (e.g., LEDs). Extends product lifespan and prevents thermal throttling.
- Enhanced Durability – Metal substrates resist warping and vibration, ideal for automotive/industrial use. Withstands temperatures up to 120°C continuously.
- Compact Design – Eliminates bulky heatsinks, enabling thinner devices. Supports double-sided component mounting.
- Cost Efficiency – Reduces reliance on external cooling systems. Lower maintenance costs due to higher reliability (MTBF ≥50,000h).
- Eco-Friendly – Aluminum cores are recyclable, aligning with sustainability goals.
- High-Power Performance – Handles power densities >20 W/cm² (e.g., IGBT modules) without degradation.
- EMI Shielding – Metal base acts as a natural shield, reducing electromagnetic interference.

Applications of Metal Core PCB Fabrication
- High-Power LED Lighting – Directs heat from LEDs to metal core, preventing premature failure. Extends lifespan and reduces maintenance costs.
- Electric Vehicle (EV) Systems – Cools battery modules, motor controllers, and charging units. Withstands vibration and thermal stress for reliable operation.
- Renewable Energy Inverters – Enhances thermal efficiency in solar/wind inverters, minimizing energy loss and boosting ROI.
- Medical Imaging & Diagnostics – Stabilizes temperature-sensitive components (e.g., lasers, sensors). Ensures precision in critical healthcare devices.
- Aerospace & Defense Electronics – Resists extreme temperatures and mechanical stress in satellite/aviation systems. Maintains performance during rapid thermal cycling.
- Industrial Motor Control – Manages heat from high-current motor drivers and inverters. Prevents thermal deformation, ensuring continuous operation.
- 5G Base Station Modules – Efficiently dissipates heat from high-frequency RF components. Maintains signal integrity and reliability in dense wireless infrastructure.
- EV Charging Infrastructure – Supports high-power DC charging by rapidly conducting heat away from power electronics. Enables faster, safer charging solutions.
MCPCB Fabrication Processes
1. Design & Engineering
- Use EDA tools to create PCB layout, adhering to IPC-2221 standards.
- Generate Gerber files and validate through Design Rule Checks (DRC).
2. Material Preparation
- Select metal substrate (aluminum/copper), insulating layer (epoxy/ceramic), and copper foil.
- Cut metal base to specified dimensions.
3. Metal Substrate Treatment
- Clean substrate to remove contaminants.
- Apply insulating layer via coating or lamination, ensuring uniformity.
4. Circuit Layer Formation
Use photolithography to pattern copper traces:
- Coat substrate with photoresist.
- Expose to UV light through circuit masks.
- Develop and etch to remove excess copper.
5. Lamination & Pressing
- Stack layers (metal base, insulating layer, copper foil) with prepreg.
- Press under high temperature/pressure to bond layers (IPC-6012 compliance).
6. Drilling & Plating
- Drill via holes for interlayer connections.
- Electroplate holes to deposit copper, ensuring conductivity (IPC-A-610).
7. Surface Finish
- Apply surface treatment (e.g., ENIG, OSP) to protect copper and enhance solderability.
8. Testing & Inspection
- Electrical test (flying probe) to verify connectivity.
- AOI for defects, thermal stress test for reliability.
9. Profiling & Cutting
- Route PCB to final shape, V-cut or bevel edges as needed.
10. Packaging & Shipping
- Final inspection, vacuum packaging to prevent oxidation.
