Conductive adhesives and conductive coatings play an important role in the electronics industry. This article will introduce the characteristics, applications, and importance of conductive adhesives and conductive coatings in the electronics industry.

Introduction: Electronic products play an important role in modern society, and conductive adhesives and coatings are important materials for keeping these electronic products stable and working smoothly. They have unique characteristics and a wide range of application fields. This article will provide a detailed introduction to conductive adhesives andconductive coatingExplore their characteristics and their importance in the electronics industry.

1、 Characteristics and Applications of Conductive Adhesives

1. High shear strength: The conductive adhesive uses a special process to dope metal fillers (such as silver particles or silver plated copper particles) into epoxy resin, silicone, or flexible polyisoprene, giving it high shear strength. This characteristic allows conductive adhesives to withstand significant forces and strains in electronic products.

2. Small coefficient of thermal expansion: The thermal expansion coefficient of conductive adhesives is small, which can effectively reduce the problem of adhesive peeling or cracking caused by temperature changes. This enables the conductive adhesive to maintain stable bonding performance even in high temperature environments.

3. Ionic purity: Conductive adhesives usually have the characteristic of ionic purity, which can effectively prevent corrosion and other damage caused by ions in electronic products.

4. Good thermal and electrical conductivity: Conductive adhesives can provide excellent thermal and electrical conductivity, which helps maintain the stable operation of electronic products. This is particularly important in the electronics industry.

Typical applications:conductive adhesiveCommonly used to bond EMI shielding channels, windows, or transparent conductive wire mesh onto permanent seams of shielding. This application can effectively provide EMI shielding, protecting electronic products from external electromagnetic interference.

2、 Characteristics and Applications of Conductive Coatings

1. Wide applicability: Conductive coatings can be sprayed on various plastic casings, such as ABS, Noryl, and PVC. This flexibility allows it to be applicable to different types of electronic products.

2. EMI shielding and anti-static protection: The filler contains metals such as silver, silver coated copper, copper, and nickel, which can effectively provide EMI shielding and anti-static protection. This helps protect electronic products from external interference and static electricity.

3. Corona shielding and surface grounding: Conductive coatings can provide corona shielding and surface grounding functions. This is particularly important in high-voltage applications and in preventing corona discharge.

4. Excellent conductivity: The conductivity of conductive coatings can usually reach 0.015 ohm/sq, which is crucial for the normal operation of electronic products.

Application example: Conductive coatings are commonly used for casings, providing 60 to 80dB shielding in the range of 30MHz to 1GHz, thereby protecting electronic products from external interference.

Conclusion: Conductive adhesives and conductive coatings play an indispensable role in the electronics industry. Their characteristics include high shear strength, low coefficient of thermal expansion, ion purity, and good thermal and electrical conductivity. Conductive adhesives are commonly used to bond EMI shielding channels and windows, whileconductive coatingIt is used to provide EMI shielding, anti-static protection, corona shielding, and surface grounding. The application of these materials can protect the stability and reliability of electronic products, thereby ensuring their normal operation in modern society.
