Anisotropic conductive adhesive (ACA) can be used in a wide range of applications. The core competitiveness of domestic enterprises needs to be enhanced.

Anisotropic conductive adhesive is a type of conductive adhesive, also known as anisotropic conductive adhesive, anisotropic conductive adhesive, or ACA/ACP in English. Anisotropic conductive adhesive has the function of unidirectional conduction and gluing and fixation. It can conduct current in the vertical direction and insulate in the horizontal direction. This is its greatest characteristic. It is a conductive adhesive used in the field of electronic component packaging.

Conductive adhesive is made of polymer materials and conductive particles. Its conductive performance is close to that of metal. According to the conductive direction, it can be divided into two categories: isotropic conductive adhesive (ICA) and anisotropic conductive adhesive (ACA). In comparison, anisotropic conductive adhesive has a higher technical content. Compared with the anisotropic conductive adhesive film (ACF), which is also an anisotropic conductive adhesive product, the anisotropic conductive adhesive has a paste-like appearance and has the advantages of stronger adhesion and higher reliability, and can be used in fine Printed circuit board manufacturing field.

According to the “2022-2026 Anisotropic Conductive Adhesive (ACA) Industry In-depth Market Research and Investment Strategy Suggestions Report” released by the Industrial Research Center shows that benefiting from the rapid development of the electronic information industry, the types and output of electronic products are constantly increasing, and the global market demand for conductive adhesives continues to grow. From 2015 to 2021, the global conductive adhesive market size has an average annual compound growth rate of 10.7%. Under this circumstance, as a conductive adhesive product with better performance, the consumption of anisotropic conductive adhesive continues to increase. my country is a major producer of electronic products. The semiconductor industry is large-scale, display panel production capacity continues to expand, packaging demand continues to rise, and there is a strong demand for anisotropic conductive adhesives.

Anisotropic conductive adhesive is suitable for scenes with ultra-fine pitch, diverse types of components, and difficult packaging. It has the advantages of good flexibility, low thermal expansion coefficient, low curing temperature, simple interconnection process, and good environmental protection. Anisotropic conductive adhesive can be used in LCD modules, LCD driver modules, camera modules, flexible circuit boards, touch screen cables, high-precision cables, integrated circuits, piezoelectric crystals, crystal oscillators, resonators, discrete In the manufacturing of devices, they are widely used in LED lighting, display panels, solar cells, communications, automotive electronics, smartphones, tablets, wearable devices, televisions, electronic tags, radio frequency identification and other industries.

Industry analysts said that the technical barriers to anisotropic conductive adhesive are relatively high. Globally, the main manufacturers include Japan’s Sony ( Sony), Japan’s Hitachi Chemical (Hitachi-Chem), China’s Taiwan TeamChem Company, China’s Taiwan Weifeng Technology (U-PAK), the United States Uninwell, the United States 3M, the United States Creative Materials, Germany’s Henkel (Henkel), Germany DELO etc. Benefiting from the development of my country’s electronic information industry, my country’s anisotropic conductive adhesive production capacity has continued to increase, but there is still a gap between high-end products and foreign companies. In the future, the core competitiveness of my country’s anisotropic conductive adhesive industry needs to be continuously improved.
