Conductive tape for electronic products

Conductive tape

Conductive tapes are flexible adhesives that conduct current on one or both sides. These tapes are a useful and cost-effective option for electronic assembly, especially in shielding or grounding applications. Conductive tape offers many advantages over other assembly methods such as soldering or mechanical fastening.

Electrical components require strong adhesives to provide the properties needed for reliable bonding and consistent electrical performance. Disconnected components and electromagnetic interference can interfere with functionality, but specialized adhesives such as conductive tapes ensure longer-lasting performance.

Types of Conductive Tapes

  • Conductive vs. non-conductive adhesive. Tapes with conductive adhesives conduct electricity at the top and bottom. The polymer that makes these tapes sticky contains tiny embedded metal particles that conduct electricity. In contrast, some conductive tapes do not have these embedded elements, so they conduct current only on non-adhesive surfaces.
  • Conductive tapes can be made from many different materials, including copper, aluminum, and conductive alloys.

Conductive tape is essentially a conductive cloth as a tape material, its characteristics are in the ordinary conductive cloth on top of a layer of "glue" special properties, this glue can be used to conduct electricity, is a conductive glue, and is the composition of nickel, and can play a shielding effect of magnetic fields.

Conductive cloth tape with nickel in the glue, and conductive glue is not very special glue, but ordinary hot melt glue or acrylic glue can be. The purpose of the glue is to make the conductive cloth has good adhesion.
The characteristics of the conductive cloth tape can be expressed in the following aspects:

  1. conductive cloth tape has a good shielding effect of magnetic fields and the effect of conductive.
  2. conductive cloth tape has a good defense against friction performance, and according to calculations, the conductive tape can be up to 5000000 times the number of anti-friction
  3. conductive cloth tape has good Z-directional conductive properties and good metal bonding properties;
  4. conductive cloth tape has good processing performance because its texture is very soft, the conductive cloth tape will not appear when the division and conductive cloth tape can resist Conductive cloth tape has good processing performance, because it is a very soft texture when the conductive cloth tape is divided will not appear burrs, and conductive cloth tape can resist the dirt left by handprints antioxidant performance is very good.

The application of conductive cloth tape due to its good characteristics, is widely used in computers, cell phones, wires or cables, and other types of electronic products and electrical products, the purpose of the application of conductive cloth tape is mainly in high-frequency transmission, conductive cloth tape can be used to shield or isolate electromagnetic waves and magnetic fields and radio wave interference with the product.

The purity is higher than 99.95%, and its function is to eliminate electromagnetic (EMI) interference, isolate the harm of electromagnetic waves to the human body, and avoid the unwanted voltage and current affecting the function. In addition, it has a good effect on the discharge of static electricity after grounding. Strong adhesive force, and good conductivity, can be cut into various specifications according to customer requirements.

Copper foil tape is divided into the single-sided adhesive and double-sided adhesive. Single-sided copper foil tape is also divided into single-conducting copper foil tape and double-conducting copper foil tape, single-conducting copper foil tape means that the adhesive side is not conductive, only the other side of the copper conductive, so-called single-conducting that is single-sided conductive; double-conducting copper foil tape means that the adhesive side is conductive, and the other side of the copper itself is also conductive, so-called double-conducting that is double-sided conductive. There are also double-sided copper foil tape and other materials used to process into more expensive composite materials, double-sided copper foil adhesive surface is also divided into two kinds conductive and non-conductive. Customers can choose according to their needs for conductivity.

Copper foil tape performance:

  • It has insulation, heat insulation, is waterproof, good adhesion, good cold resistance, easy to tear, can eliminate electromagnetic interference (EMI), isolate the harm of electromagnetic waves to the human body, to avoid the impact of voltage or current of several properties

Copper foil tape Applications

  1. Applicable to all kinds of transformers, cell phones, computers, PDAs, PDP, LCD monitors, notebook computers, copiers, and other electronic products within the need for electromagnetic shielding.

Aluminum foil tape, using high-quality pressure-sensitive adhesive, good adhesion, strong adhesion, anti-aging and other effects!

Purity higher than 99.95%, its function is to eliminate electromagnetic (EMI) interference, isolate the harm of electromagnetic waves to the human body, avoid unwanted voltage and current, and affect the function. In addition, it has a good effect on the discharge of static electricity after grounding. The material is polyester fiber, which is not easy to crack and damage after repeated use or repeated bending. It has strong adhesion and good electrical conductivity, and can be easily wrapped and attached to the wire, and can be cut to various specifications according to customer requirements.

Aluminum foil tape Applications

  • Aluminum foil tape is suitable for all kinds of transformers, cell phones, computers, PDAs, PDPs, LED monitors, notebook computers, copiers, and other electronic products where electromagnetic shielding is required. It is used for wrapping outside the vapor duct to prevent the temperature from being dissipated outside. Non-conductive copper foil tape uses and instructions: instead of enameled wire, various types of transformer shielding.

Tinned copper foil conductive tape is in 99.99% of the calendered pure copper foil, plated with 0.002mm metal tin so that the surface of the easy-to-oxidize copper foil has a protective layer, increasing the use of copper foil, making it suitable for high salt spray, high water vapor occasions.

  1. After tin plating on the surface of copper foil, it makes the surface of copper foil, which is easy to oxidize, has a protective layer, and copper foil amine tape is not easy to oxidize, prolonging the service life and increasing the use range of copper foil to make it suitable for high salt spray and high water vapor occasions.
  2. For the need to weld on the surface of the hole foil tape in related electrical products, the tinned hole foil tape welding process is smoother.
  3. Due to the oxidation resistance of tin on the surface of copper foil, tinned copper foil tape is more durable and long-lasting in its shielding function.

Tinned copper foil tape applications:

  • Apply to outdoor discharge static electricity occasions, longer service life.
  • Application in communication cable.
  • Application in high-frequency transformers that need to be soldered
