Electroplating a certain thickness of other metal layers such as gold, silver, tin, nickel, graphene on the surface of copper foil

The Advanced Institute Technology XJY-25 series belongs to a special categoryElectroplated copper foilCopper foil (phosphor bronze, titanium copper, brass, pure copper, etc.) is electroplated with a certain thickness of other metal layers such as gold, silver, tin, nickel, graphene, etc., in order to achieve better electrical performance, such as high conductivity, corrosion resistance, oxidation resistance, solderability, high shielding, absorption and other special functions. Advanced Institute Technology produces special electroplated copper foil to better serve the needs of various high-end electronic products in the 5G era.

The shielding of electrical signals mainly relies on the excellent conductivity of copper itself, while magnetic shielding requires the conductive substance "nickel" on the rubber surface of copper foil tape to achieve the effect of magnetic shielding. Therefore, it is widely used in digital products such as mobile phones and laptops. middle.

1、 Classification of Gold Plated Copper Foil Tape

1. Gold plated copper foil tape is divided into single-sided tape and double-sided tape

2. Single sided adhesive coatingGold plated copper foil tapeIt is divided into single conductor copper foil tape and double conductor copper foil tape. Single conductor copper foil tape refers to the adhesive surface that is non-conductive, with only the other side of copper conducting, hence it is called single conductor, meaning single-sided conductive. Double sided gold-plated copper foil tape refers to one side of the tape being conductive, while the copper on the other side is also conductive.

3. There is also double-sided adhesive copper foil tape used for processing into relatively expensive composite materials with other materials. Double sided coated copper foil also has two types of adhesive surfaces: conductive and non-conductive. Customers can choose according to their own requirements for conductivity.
2、 Characteristics of Gold Plated Copper Foil Tape

1. Gold plated copper foil has low surface oxygen properties and can adhere to various substrates such as metals, insulation materials, etc., with a wide temperature range. Mainly used for electromagnetic shielding and anti-static, the conductive copper foil is placed on the surface of the substrate and combined with the metal substrate, which has excellent conductivity and plays a role in electromagnetic shielding. The purity of gold-plated copper foil tape is higher than 99.95%. Its function is to remove electromagnetic (EMI) interference, isolate the harm of electromagnetic waves to the human body, and avoid unnecessary voltage and current affecting functions.

2. Shielding Material Series Conductive Copper Foil Tape SingleDouble conductive copper foil tapeThe thickness is 18U-25U-35U-50, the length is 50M, and the width is arbitrary. It can be molded into various irregular shapes. It is an essential accessory in the electronics industry. Main applications include transformers, mobile phones, computers, and shielding applications for electronic products.

3. Double sided conductive copper foil tape has conductive acrylic adhesive on one side and conductive properties on both sides.

4. One side of the single-layer conductive copper foil tape is backed with non-conductive acrylic adhesive, and the adhesive surface is non-conductive.

3、 Copper foil tape is mainly identified from the following two aspects:

1. Appearance:Double lead copper foil tapeThe bonding surface contains fine particles (metal particles, which play a conductive role) and is slightly uneven; The adhesive surface of the single lead copper foil is free of fine particles and smooth.

2. Testing: Use a low impedance tester for measurement. The general resistance value of a double conductor is 0.01-0.03 ohms, and no current flows through a single conductor.

In addition, copper foil tape has a good effect on electrostatic discharge after grounding objects. It has strong adhesion and good conductivity. Advanced Institute Technology can cut into various specifications according to customer requirements.
