Copper Core PCB Thermal Performance & Construction
Get copper core PCBs with controlled metal thickness, thermal dielectrics, and copper circuits matched to your heat dissipation, electrical insulation, and mechanical requirements.
Copper Core PCB Stackup & Materials
A copper core provides high thermal conductivity for heat spreading, while the dielectric and circuit copper determine how heat transfers from components into the metal base. LZJPCB supports custom copper core constructions for power electronics and high-heat-load applications.
The cross-section must name the material grade, thickness, and isolation to form a complete released construction.
- Copper Core — High-conductivity metal base for heat spreading.
- Board Thickness — 1.0–2.0 mm finished PCB thickness.

Copper Core PCB Thermal Conductivity & Heat Dissipation
Improve heat transfer from power components to the heat sink with copper core PCBs designed around your actual thermal load. Dielectric properties, copper geometry, mounting pressure, and contact area all influence the final thermal resistance.
Compare complete constructions under the same heat source and boundary conditions before confirming the copper core route.

Frequently Asked Questions About Copper Core PCB
The word "copper PCB" can describe ordinary circuit copper, a copper metal base or unusually thick conductive copper. Open the relevant question to identify the construction before you compare suppliers or send an RFQ.
Copper PCB vs Copper Core PCB vs Heavy Copper PCB
"Copper PCB" is ambiguous because nearly every conventional PCB uses copper circuitry. A copper core PCB uses copper as the metal base / substrate behind an insulating dielectric and circuit layer. A heavy copper PCB is defined by thick conductive copper features and does not automatically use a copper metal core.
- Decision
- Conventional PCB
- Copper Core PCB
- Heavy Copper PCB
- Defining feature
- Copper circuit on a standard laminate system
- Copper metal base / core with insulating dielectric
- Unusually thick conductive copper features
- Primary route
- General signal, power and mixed functions
- Heat spreading into a defined mechanical interface
- High current, thermal mass or robust conductive features
- What to specify
- Laminate stackup and circuit copper
- Core, dielectric, circuit copper and interface
- Base / finished copper, geometry and current target
Aluminum PCB vs Copper Core PCB
Both are metal-base PCB routes, but the right choice depends on the complete dielectric, metal thickness, geometry, mass, interface, availability and cost. Compare both constructions under the same heat source and boundary conditions rather than choosing from one generic conductivity value.
- Decision
- Aluminum PCB
- Copper Core PCB
- Metal base
- Aluminum base / substrate
- Copper base / core
- System balance
- Often considered for weight, availability and commercial fit
- Considered when project heat spreading or mechanics justify it
- Final selection
- Validate dielectric and enclosure interface
- Validate dielectric, core and enclosure interface
