Comprehensive Guide to Copper Tape: Uses and Types

Copper tape is a thin strip of copper that is backed with an adhesive. It is highly flexible and can easily be shaped to fit a variety of uses and environments. It is a conductive material, meaning it can carry electrical currents, making it useful for a wide range of electrical and electronic applications.

There are two main types of copper tape: conductive and non-conductive. Conductive copper tape can conduct electricity on both the top and bottom of the tape, while non-conductive copper tape is only conductive on one side. This makes each type of tape best suited for different applications.

In the following sections we will explore in more detail how copper tape is used in these different scenarios.

There are two principal types of copper tape: conductive and non-conductive. We'll explore each of these in more detail below.

Conductive copper tape is designed to conduct electricity on both sides of the tape. This makes it a useful material for creating electrical connections in a wide range of applications.

One of the most common uses of conductive copper tape is in the creation of paper circuits. Paper circuits are a type of low-voltage electrical circuit that are often used in DIY or educational settings. Conductive copper tape is used to provide the current from one part of the circuit to another, making it an ideal material for this type of project.

Conductive copper tape can also be used in a wide range of other applications including:

• Repairing damaged traces on circuit boards

• Creating electrical connections in electronic devices

• Shielding sensitive electronic components from electromagnetic interference

It is worth noting that the strength of the electrical connection made with conductive copper tape can fade over time, so alternative methods of connection may be needed to ensure continued conductivity over prolonged periods. Similarly, a single continuous strip of conductive copper tape will always be a more effective conductor than multiple strips joined together. Lastly, it should also be noted that the conductive adhesive on the tape is not designed to carry high levels of current.

Non-conductive copper tape is only conductive on one side, typically the top of the tape. This makes it less suitable for electrical applications, as it cannot be used to create electrical connections in the same way that conductive copper tape can.

Non-conductive copper tape is often used in applications where the conductive properties of the tape are not needed. One of the most common uses of non-conductive copper tape is as a slug and snail deterrent. When used in this way, the tape is typically placed around the edges of plant pots or garden beds. Slugs and snails are repelled by the copper and will avoid coming into contact with it.

Non-conductive copper tape can also be used in a wide range of craft and decorative applications. Due to its attractive appearance, it is often used in projects where its metallic sheen can add a touch of elegance.

Copper tape can be used in a wide range of soldering applications. It is often used as a replacement for traditional wire in situations where a more flexible or low-profile solution is needed.

One of the most common uses of copper tape in soldering is in the creation of stained glass artwork. When creating stained glass pieces, hobbyists will typically use copper foil tape to wrap the glass pieces. This creates a handy guideline to follow when soldering the separate pieces together into the final image.

Copper tape is also commonly used in the creation of paper circuits. When creating paper circuits, copper tape is typically used to provide the current from one part of the circuit to another. This makes it an ideal material for this type of project.

When using copper tape in soldering applications it is important to ensure that the tape is in direct contact with the materials that you want to connect. For example, when creating stained glass pieces you would need to ensure that the tape is in direct contact with the glass pieces that you are using.

Copper tape is commonly used in electromagnetic shielding applications. Electromagnetic interference (EMI) can be problematic in certain situations. It can damage delicate components and cause excess electronic feedback, so shielding is an important way to safeguard and protect a range of equipment. Shielding essentially works by creating a conductive, grounded enclosure (a Faraday cage) around the component/s.

Copper foil tape can be used to shield components in a range of applications and environments. This could include everything from RF shielding to shielding a guitar pickguard to protect the instrument’s electronics from outside interference.

Copper tape can also be used in combination with other materials to provide additional shielding. For example, it is common to see copper tape used in combination with conductive fabrics to create more effective shielding solutions.

Copper shielding paint is an alternative to copper shielding tape. It is available in aerosol form, designed to provide a low-resistance, RFI and EMI shielding coating for plastic electronic housings. Boasting enhanced adhesion, even surface coating, and strong scratch-resistant properties, copper shielding paint has a wide range of benefits and can be used with a variety of substrates.

Copper shielding paint is typically used in situations where a more seamless or integrated shielding solution is needed. It can be used to shield electronic devices or components without the need for additional materials or components.
