Analysis of the main materials and structure of copper foil tape

1、 The main material of copper foil tape

1. Copper foil

Copper foil isCOPPER FOIL TAPEThe core material is usually made of high-purity (such as CU 99.98%) electrolytic copper. Copper foil has good conductivity, ductility, and corrosion resistance, which is the key to achieving electromagnetic shielding function. The thickness of copper foil is usually between 0.018mm and 0.05mm, which can ensure sufficient conductivity and meet different application requirements.

2. Adhesive

The adhesive in copper foil tape is the key part that connects copper foil and substrate. There are various types of adhesives, including ordinary pressure-sensitive adhesives (non-conductive) and conductive acrylic pressure-sensitive adhesives. Among them, conductive acrylic pressure-sensitive adhesive not only has good adhesion, but also provides conductive function in specific situations, further enhancing electromagnetic shielding effect.

3. Substrate

The substrate is the supporting part of copper foil tape, usually made of polymer materials such as PET (polyethylene terephthalate). The selection of substrate needs to consider factors such as mechanical strength, temperature resistance, and chemical solvent resistance to ensure that copper foil tape can maintain stable performance in various environments.

2、 Structure of Copper Foil Tape

The structure of copper foil tape is relatively simple but the design is exquisite, mainly including copper foil layer, adhesive layer, and substrate layer. Among them, the copper foil layer is located in the middle, with adhesive coated on both sides, and tightly bonded to the substrate through the adhesive.

1. Single sided adhesive copper foil tape

Single sided adhesive copper foil tape refers to copper foil coated with adhesive only on one side, while the other side is exposed or has a non-conductive layer. According to the different conductivity properties,Single sided adhesive copper foil tapeIt can be divided into single conductive copper foil tape and double conductive copper foil tape. Single conductive copper foil tape only conducts electricity on the copper foil surface, while double conductive copper foil tape conducts electricity on both sides, making it suitable for applications that require double-sided conductivity.

2. Double sided adhesive copper foil tape

Double sided adhesive copper foil tapeBoth sides of the copper foil are coated with adhesive, and conductive or non-conductive adhesive can be selected as needed. This structure makes copper foil tape more flexible when combined with other materials, enabling the formation of composite materials with specific electromagnetic shielding and conductivity properties.
