I’ve been in the electric conduction adhesive (ECA) supply business for quite some time, and one question that frequently comes up is, "What is the definition of electric conduction adhesive?" In this blog, I’ll delve into the details of ECA, sharing my insights based on years of hands – on experience in the industry. Electric Conduction Adhesive<\/a><\/p>\n

What is Electric Conduction Adhesive?<\/h3>\n

Electric conduction adhesive is a special type of adhesive that has the ability to conduct electricity while also providing mechanical bonding. It is a complex material composed of a polymer matrix and conductive fillers. The polymer matrix is usually a resin, such as epoxy, silicone, or polyimide. These polymers provide the adhesive properties, allowing the ECA to bond two or more substrates together. The conductive fillers, on the other hand, are responsible for the electrical conductivity.<\/p>\n

Common conductive fillers include metals like silver, copper, gold, and nickel. Silver is the most widely used conductive filler due to its excellent electrical conductivity and relatively good chemical stability. Copper is also a popular choice because of its high conductivity and lower cost than silver, but it is more prone to oxidation. Gold is used in applications where high conductivity, resistance to corrosion, and biocompatibility are required, such as in medical devices. Nickel is often used when cost – effectiveness is a major concern, although its conductivity is lower compared to silver and copper.<\/p>\n

How Electric Conduction Adhesive Works<\/h3>\n

The working principle of ECA is based on the connection of the conductive fillers within the polymer matrix. When the adhesive is applied and cured, the conductive fillers come into contact with each other, forming a conductive path. The electrical current can then flow through these conductive paths, allowing the adhesive to conduct electricity.<\/p>\n

The degree of electrical conductivity of ECA depends on several factors. Firstly, the type and amount of conductive filler play a crucial role. Generally, the higher the content of conductive filler, the better the electrical conductivity. However, if the filler content is too high, it may affect the mechanical properties of the adhesive, such as its flexibility and adhesion strength.<\/p>\n

Secondly, the dispersion of the conductive filler in the polymer matrix is also important. A uniform dispersion ensures that there are sufficient conductive paths throughout the adhesive, leading to better conductivity. In addition, the curing process of the adhesive can also impact its conductivity. Proper curing conditions, such as temperature, time, and pressure, are necessary to achieve optimal electrical and mechanical properties.<\/p>\n
