Conductive adhesive films have broad application prospects in the electronic and electrical fields, and anisotropic conductive adhesive films are their representative products.

Conductive adhesive film refers to a lead-free connection material containing a nickel-silver metal plating structure. It is usually made of conductive adhesive coated on a base film. Conductive adhesive films have the advantages of excellent electrical conductivity, good thermal conductivity, processability, good heat resistance, high peel strength, and good solder resistance. They are widely used in electronic and electrical fields such as conductive circuit bonding, microelectronic packaging, and printed circuit boards. There are many applications.

Conductive adhesive film is usually composed of conductive filler and matrix resin. Polyurethane resin, acrylic resin and epoxy resin are commonly used in its production process. Taking epoxy resin as an example, it has the advantages of good heat resistance, high bonding strength, and corrosion resistance. It is widely used in fields such as plastics, films, and electronic chemicals. my country is the world’s largest producer of epoxy resin. As the COVID-19 prevention and control policies are gradually relaxed, companies have resumed work and production, driving the further expansion of epoxy resin production capacity. Against this background, the development of my country’s conductive adhesive film industry has further accelerated.

Anisotropic conductive film (ACF) is a representative product of conductive film. It has three major properties: insulation, conductivity and bonding, and is widely used in the field of display panels. In recent years, with the gradual transfer of global display panel production capacity to my country, the prosperity of OLED, LCD and other industries has further improved, driving the market demand for anisotropic conductive adhesive films to further grow. However, currently, due to factors such as high technical barriers, my country’s anisotropic conductive adhesive films mainly rely on imports, which brings certain challenges to the development of the conductive adhesive film industry.

According to the “2023-2028 China Conductive Adhesive Film Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, Conductive adhesive films are widely used in electronic and electrical fields such as conductive circuit bonding, microelectronic packaging and printed circuit boards. Benefiting from national policy support and the improvement of independent research and development capabilities of local enterprises, my country’s printed circuit board (PCB) production capacity has rapidly expanded and output has continued to grow, becoming the world’s largest producer. Conductive adhesive film can be used to bond and encapsulate printed circuit boards. Driven by downstream demand, its industry development space has further expanded.

Compared with overseas developed countries, my country’s conductive adhesive film industry started late. The main production companies include Fangbang Co., Ltd., Lucky New Materials, NanoVis Technology, etc. Lucai New Materials is a representative enterprise of conductive adhesive films in my country. It focuses on the research and development, production and sales of new materials such as photosensitive dry films, conductive adhesive films, and electromagnetic shielding films. Its products have been widely used in the field of electronic products.

Industry analysts said that conductive adhesive films have the advantages of excellent electrical conductivity and good thermal conductivity, and are widely used in the electronic and electrical fields. The conductive adhesive film industry has high technical barriers, and there is still a certain gap between my country’s output and quality compared with overseas developed countries. In the future, with the improvement of independent research and development capabilities of local enterprises, my country’s conductive adhesive film industry will gradually develop in the direction of high performance.
