As an important driving force for today's social progress and economic development, the electronics industry has become a key development industry in many countries in the future. At present, electronic products are becoming more and more lightweight, multi-functional and high-performance. As an important auxiliary material for electronic products, adhesives are widely used. In addition to traditional sealing, bonding, potting and coating functions, adhesives also have special functionalities, such as electrical conductivity, thermal conductivity, insulation, dielectric properties, waterproof and dustproof properties, corrosion resistance, and flame retardancy. properties and optics, etc.
SMT/SMD electronic glue
SMT/SMD electronic glue, also known as patch red glue, is a low-temperature curing improved epoxy glue that can form excellent bonding force between various materials in a very short time. It has excellent performance, is easy to store, and is widely applicable to various needs. Low temperature curing heat sensitive components.
According to the characteristics of different SMT glues, SMT glues with high shear dilution viscosity are suitable for use in various ultra-high-speed dispensing machines; SMT glues with viscosity characteristics and rheotropic properties can effectively prevent glue overflow on PCB boards and are suitable for use in various ultra-high-speed dispensing machines. Steel mesh/copper screen printing glue process.
COB/COG electronic glue
COB/COG electronic glue, also known as cofferdam filler glue, is a high-quality single-component epoxy encapsulation glue with excellent solder resistance, moisture resistance, temperature cycling and good fluidity. It has a low thermal expansion coefficient and can reduce deformation. Suitable for LCD, PDA, calculator and other electronic products. After curing, it also has excellent performance characteristics such as low shrinkage, low moisture absorption, flame retardancy, and bending resistance. It is especially suitable for IC bonding and provides protection.
The potting glue is usually liquid before curing and has fluidity. After curing, it can prevent moisture, water, and corrosion to improve product stability and service life. According to its material, it can be divided into epoxy potting glue, silicone potting glue, and polyurethane potting glue. According to its use requirements and product characteristics, it can be poured manually or by machine. It is mainly used for electronic components, modules, transformers, and power supplies. , potting of electronic components such as sensors.
Thermal conductive adhesive can be said to be specially designed and produced for the use of gaps to transfer heat. It can fill gaps and complete heat transfer between heating parts and heat dissipation parts. It also plays the role of insulation, shock absorption, sealing, etc. It is often used in components such as transformers, transistors, and CPU chips that generate large amounts of heat and require heat dissipation.
With the widespread and in-depth use of electronic glue, electronic products have higher and higher requirements for electronic adhesives, requiring their functions to become more and more diversified. For example, conductive glue can not only achieve physical connection, but also conduct electricity. dual role. This development trend is one of the important signs of the progress of electronic adhesives. While promoting the development of the glue industry, it also poses new challenges.
