Product selection

MCPCB Types We Manufacture

Select the structure from the heat path, circuit density, mechanical package and electrical isolation requirement—not from the material name alone.

Material type 01

Aluminum Core PCB

Aluminum core MCPCB combines a copper circuit, thermally conductive dielectric and aluminum base. It suits lighting, power conversion and control products that need efficient heat spreading with controlled electrical isolation.

Thermal specification

MCPCB Materials & Thermal Performance

Material name, thermal conductivity, thermal resistance and thickness describe different parts of the heat path. A valid purchase specification keeps each one explicit.

Material system

Metal Core & Dielectric Materials

The metal core spreads heat. The thermally conductive dielectric transfers heat while maintaining electrical isolation. Copper carries current and forms the solderable circuit pattern.

  • Aluminum or copper core grade and thickness are fixed in the approved build.
  • Dielectric material, dielectric thickness and datasheet thermal conductivity are named together.
  • Copper weight is selected for current, heat spreading and etch geometry.
  • Thermal interface pads used in the finished assembly remain separate from the PCB dielectric specification.

Performance terms

MCPCB Thermal Conductivity & Thermal Resistance

Thermal conductivity is a material property. Thermal resistance describes how strongly the complete heat path resists heat flow. A high conductivity value does not by itself define board-level thermal performance.

Thermal conductivity (W/m·K)Belongs to the selected dielectric or metal material datasheet.
Thermal resistance (°C/W)Calculated from material, thickness, contact area, copper pattern and interface stack.
  • Quote requests state the target material value and the matching dielectric thickness.
  • Thermal simulation uses the actual component footprint, copper area and mechanical interface.
  • Qualification compares the approved stackup and test method, not isolated marketing numbers.
Dimensional stack

MCPCB Thickness & Construction

Finished MCPCB thickness is the sum of the metal core, thermal dielectric, copper and finished coating. The quotation lists these elements separately so purchasing can compare equivalent constructions.

  • Total board thickness and tolerance are stated on the fabrication drawing.
  • Metal core thickness is defined independently from the finished board thickness.
  • Dielectric thickness remains visible because it directly influences isolation and heat transfer.
  • Finished copper and solder mask requirements stay linked to current and assembly conditions.

MCPCB Applications

MCPCB creates value where the circuit must move heat into a chassis, heat sink or airflow path while preserving electrical isolation and production repeatability.

LIGHTING

LED MCPCB & Metal Core PCB for Lighting

LED bulb boards, DOB boards, star MCPCB, linear strips, spotlight plates and 12 V LED modules use the metal core to spread heat away from LEDs and driver components. Wattage labels such as 3 W, 5 W, 9 W, 10 W or 25 W do not define one standard outline; the mechanical drawing fixes dimensions and mounting features.

01
Lock the thermal material system

Metal grade, core thickness, dielectric code, dielectric thickness, conductivity reference and copper are named together.

02
Release the actual heat path

03
Keep evidence tied to that build

Material records, dimensions, electrical isolation and requested thermal evidence follow the same order and lot.

Frequently Asked Questions About MCPCB

Short definitions for product selection without turning the product page into a general PCB glossary.

What Does MCPCB Stand For?

MCPCB stands for Metal Core Printed Circuit Board. The term also appears as metal core PCB, metal-backed PCB or metal-based PCB. It describes a circuit board that uses a metal base to spread heat away from electronic components.

What Is an MCPCB?

An MCPCB is a printed circuit board built with a copper circuit layer, thermally conductive electrical-insulation layer and metal core. The dielectric transfers heat from the circuit into the metal base while isolating the copper electrically. Aluminum and copper are the primary core options on this page.

What Is an MCPCB for LED?

An LED MCPCB is a metal core board designed to carry LED circuits and move heat into a luminaire body or heat sink. DOB, star, strip, bulb and spotlight boards are application shapes; the electrical design, outline, voltage, wattage and mounting dimensions come from the product specification. See the LED application section.

What Is the Difference Between a PCB Core and a Metal Core PCB?

In a conventional multilayer PCB, a “core” is a copper-clad dielectric laminate used inside the stackup. In a metal core PCB, the core is a metal base used for heat spreading. The two terms describe different materials and functions, so a generic “core PCB” request must state whether it means a laminate core or an MCPCB metal base.
