Heavy Copper PCB Manufacturing

Copper core circuit boards are a type of metal core PCB. With their layered design using a copper base, these PCBs offer superior thermal conductivity. Unitepcb has customized solutions for your copper core PCB requirements. Experience the advantages of high thermal conductivity with specially designed copper core circuit boards from Unitepcb.

• Base layer: The base layer is made of a copper substrate that offers high thermal conductivity and heat transfer.
• Thermal insulation layer: Copper core PCBs use prepreg or another high thermal conductivity insulation to improve heat transfer.
• Circuit layer: Copper foil makes up the circuit layer, and these often range from 1 to 10 ounces.
• Dielectric layer: An added dielectric layer absorbs the heat that travels through the circuit layer and sends it to the copper substrate for dispersion.

Benefits of Heavy Copper PCB

The main benefit of heavy copper PCB is the capability to support frequency to excessive current, elevated temperatures and recurring thermal cycling, which can do harm to aregular circuit board in seconds. What’s more, there is a great demand for heavy copper PCBs in the computer, automotive, military, and industrial controls.

In addition, there are some other benefits of heavy copper PCB as follows:

1. Compact product size because of several copper weights on the same layer of circuitry;

2. Onboard high-power-density planar transformers;

3. Heavy copper-plated vias pass the elevated current through the PCB and are good for transferring the heat to an outer heat sink.

Uses of Heavy Copper PCB

As a material with high thermal conductivity and heat dissipation, copper core PCBs are the ideal solution for high-power applications. When you’re working with high-temperature projects, copper core circuit boards offer the best thermal conductivity and heat dissipation available. Your PCB will survive these severe conditions without sustaining damage to critical components.

Metal core PCBs were initially created for high-power switching supply, but they also have a significant presence in light-emitting diode (LED) applications, such as traffic lights. Copper core PCBs support higher-density designs, enabling more complex projects while operating at high currents.

Possible applications include:

• Lighting: Street lights, interior lighting and camping lanterns
• Automotive: Headlights and power controllers
• Telecommunications: Filtering appliances and high-frequency amplifiers
• Audio: Output, input and power amplifiers
• Computers: Central processing unit (CPU) boards and power devices
• Power supply: Solid-state relays, bridges, power rectifiers and converters
• Medical tools: Operating room and surgical lighting, power converters and high-power scanning technology

Our Capabilities

Unitepcb manufacturers can develop and produce excellent high quality heavy copper PCB products. We can provide heavy duty copper PCB manufacturing services with 13 ounces of copper. We are able to build differential copper plating on the PCB based on the client’s design. We do have a guideline for the engineers to follow during the design to ensure the trace and space is compensated for heavy copper designs to consider etch back factor in manufacturing.
