Heavy Copper PCB Manufacturing
Heavy copper PCB and aluminum PCB manufacturing for thermal management and power electronics. Metal core PCBs from 2oz to 6oz copper weight, delivering superior heat dissipation for EV, LED, and high-current applications.
What is a Metal Core PCB?
A Metal Core PCB (MCPCB) uses a metal base — typically aluminum or copper — as the core substrate for superior heat dissipation. Unlike standard FR-4 boards, MCPCBs channel heat away from power-hungry components, improving performance and longevity.
Heavy copper and aluminum PCB boards are widely used in electric vehicle battery management systems and power electronics, and our low-volume PCB assembly service is ideal for prototype through production runs.
Aluminum Core
1W/mK Thermal Conductivity
Cost-effective and widely used in LED lighting and general power applications. Aluminum base provides efficient heat spreading at a competitive price point.
Copper Core
380W/mK Thermal Conductivity
Superior thermal performance for high-power-density applications. Copper base delivers unmatched heat dissipation for demanding designs.
Key Benefits
Superior Heat Dissipation
The metal base layer rapidly conducts heat away from components, reducing junction temperatures and extending product lifespan significantly.
Higher Current Capacity
Thicker copper layers on metal core substrates handle higher current loads without overheating, ideal for power electronics and LED arrays.
Enhanced Mechanical Strength
The metal base provides rigidity and dimensional stability, reducing warpage and improving reliability in high-vibration environments.
Applications
Metal core PCBs excel in thermally demanding environments.
LED Lighting Systems
High-power LED modules, street lighting, and automotive headlamps that require efficient thermal management.
Power Electronics
Motor drives, power supplies, inverters, and converters that generate significant heat during operation.
Automotive & Aerospace
Engine control units, LED taillights, and avionics that demand thermal reliability under extreme conditions.

Heavy Copper vs Aluminum PCB: What's the Difference?
Both are metal core PCBs, but they serve different thermal and current-handling needs. Compare heavy copper PCB and aluminum PCB across the specs that matter.
| Attribute | Heavy Copper PCB | Aluminum PCB |
|---|---|---|
| Copper Weight | 2oz – 6oz (70μm – 210μm) | 1oz – 2oz (35μm – 70μm) |
| Thermal Conductivity | High — thick copper plane spreads heat across the board | ~1 – 2 W/mK via aluminum base, ~380 W/mK on copper core |
| Typical Applications | EV BMS, power converters, motor drives, high-current bus bars | LED lighting, street lamps, general power supplies |
| Cost | Higher — more copper and longer plating cycles | Lower — economical aluminum base substrate |
| Processing Difficulty | Higher — heavy copper etching, lamination, and via plating require tight control | Moderate — standard MCPCB process, easier to manufacture |
