Adhesives have the advantages of firmly bonding the same or different materials together, no stress concentration at the bonded joints, relatively high bonding strength, and easy automation of the bonding process. Therefore, they have been widely used in many fields, especially as one of the auxiliary materials in the electronics industry. With the increasing requirements for miniaturization, light - weight, and high - performance of electronic products, the adhesives used in the electronics industry are not only increasing in variety and quantity but also improving in performance. Due to the wide variety of electronic adhesives, strict performance requirements, and high added value, they hold a very important position in the adhesive industry.
