Superior Quality Copper Clad PCB from PCBTok

Copper Clad PCBs are boards that have a thin layer of copper covering the entire board. It is also known as a PCB with a thin layer of copper attached to it. Copper cladding is a process in which the surface of a PCB is plated with a thin layer of copper after the board has been manufactured.

PCBTok has a range of copper clad printed circuit boards to choose from. We offer high quality copper clad PCBs with a variety of options for you to build your next electronic project.

Copper Clad PCB By Types

Rigid Copper Clad PCB

A neoteric assembly of rigid substrate and thin copper clad laminate. The copper is deposited on one or both sides of a rigid base material, usually glass epoxy resin.​

Flex Copper Clad PCB

Made for applications involving demanding mechanical constraints, high-temperature environments, and exposure to chemicals. Ideal for sensors, displays, etc.

Metal-Based PCB

Our metal-based copper clad PCBs are ideal for high-power and high-frequency applications. Metal-based means that the offers superior heat dissipation and better durability.

Ceramic-Based PCB

Made using a unique process that combines the attributes of epoxy and ceramic components to form a fiberglass-reinforced structure with pure copper cladding.

Paper-Based PCB

Manufactured using a low cost, environmentally friendly process and can be used in the same applications as traditional FR4 epoxy boards.

Organic Resin Based PCB

For applications where low signal loss, high speed and good dielectric properties over a wide temperature range are required. It offers excellent electrical characteristics.

What is a Copper Clad PCB?

Copper clad PCBs are a type of circuit board that is made up of two layers: a copper layer and another layer on top. The main difference between a copper clad PCB and other types of PCBs is that a copper clad has an outer layer of copper.

Copper clad PCBs are typically used for high-speed applications because they have multiple layers for electricity to pass through. This means that there are fewer restrictions on the movement of electrons in this type of circuit board than in others.

Copper cladding also improves heat dissipation on your board by increasing surface area and allowing air flow around components like chipsets or memory modules. This can allow you to lower operating temperatures without having to install larger fans or heatsinks than you would otherwise need on a non-copper-clad board—which could save money in both hardware costs and installation time/effort for technicians who have to install these components into computers or other devices like smartphones or tablets

Materials Used in Copper Clad PCB

Copper Clad PCB is made up of many different materials. Some of these materials are more important than others, but all of them are necessary to make a good product.

The most important material used in Copper Clad PCB is copper. Without this metal, there would be no conductivity between components and no way to keep electricity flowing through the device. Copper is also very malleable and can be shaped easily into different forms.

Another important material used in Copper Clad PCB production is epoxy resin. This substance is what holds everything together after it has been molded by the manufacturer. It also provides protection against corrosion and environmental damage for the long term use of these devices.

Copper Clad PCB Features

Copper Clad PCBs are a type of substrate that has copper layer on both sides. It is used for high-frequency circuits, especially as the signal line in high-speed communication networks. The advantages of copper clad PCBs are:

• High efficiency, good power dissipation capability, and low thermal resistance.
• High electromagnetic interference (EMI) shielding performance.
• Wide operating temperature range.
• Good chemical stability.
• Long service life

• The copper-clad PCBs are reasonably priced, especially considering the high quality and convenience they offer.

Copper Clad PCB Fabrication

What to Know in Manufacturing Copper Clad PCBs

Copper clad PCBs are made using two different processes: etching and laminating.

The etching process involves applying an acid solution to the copper surface, which removes all other materials except for the copper itself.

The laminating process involves applying a thin layer of adhesive tape to the copper surface before applying another layer of plastic film over it.

One thing that sets copper clad PCBs apart from many other types of printed circuit boards is their flexibility—they can withstand high temperatures without warping or bending out of shape like most other types do under similar conditions (like acrylic or phenolic substrates).

What to Know in Manufacturing Copper Clad PCBs

You will want to make sure that the board has enough clearance between components and traces. Make sure that your design doesn’t have any overlapping or shorted traces, which can cause problems with your circuit’s performance.

You should pay attention to the thickness of the copper on your board. The thicker the copper layer, the more reliable your circuit will be. However, this also makes it harder for components to fit into their allotted spaces on the board.

Make sure that your components are placed correctly and that they are placed close enough together so that they don’t interfere with each other’s operation.
