MCPCB / Aluminum PCB Manufacturing — High Thermal Conductivity Metal-Core PCBs
Reliable aluminum-based and metal-core PCB manufacturing with high thermal conductivity, stable mechanical performance and consistent batch-to-batch quality for LED, power modules, automotive and industrial applications.
Metal-core PCBs (MCPCB) use aluminum or copper substrates to achieve superior heat dissipation, allowing power electronics and LED systems to operate with higher efficiency, longer lifespan and greater reliability.
LinkPCBA delivers stable, mass-production-ready MCPCB and aluminum PCB solutions through our audited supply-chain partners combined with internal engineering validation and QC inspection.
Customer Challenge — Heat Dissipation & Power Stability
An international LED lighting manufacturer required a high-power MCPCB for a compact light engine. Key challenges included:
- Efficient thermal dissipation under high current
- Maintaining dielectric isolation while enabling fast heat transfer
- Ensuring flatness for COB/LED mounting
- Achieving stable thermal resistance (Rθ) across large production lots
- Preventing delamination under high temperature cycles
- Ensuring consistent solderability and aluminum oxidation protection
These requirements exceed standard FR4 PCB capabilities.
