After years of development and accumulation, the performance of my country's electronic adhesive products has been greatly improved, the industry's production capacity and output have continued to increase, and product types have become increasingly rich. Compared with traditional mechanical fixing methods such as welding, riveting, and screws, adhesives are the most effective bonding method since the development of new materials. Today, with the rapid development of science and technology, electronic products, especially consumer electronics products, are changing with each passing day. The diverse application scenarios have put forward more stringent requirements on the adaptability and performance of adhesives.
The role of electronic adhesives in modern manufacturing
Connection effect
This can be said to be the most basic function of glue. There are two main usage scenarios. The first is to connect different materials or components through precise glue dispensing during the product assembly process, which requires fast curing and reliable bonding; the second is to transmit external forces while bearing load forces, and its main function is to tightly connect the two parts. Fastening together and transmitting external forces from one part to another requires glue with high bonding strength, fast curing speed and good impact resistance. For example, the connection between the motor rotor and the shaft uses this principle.
Protective effects
As the requirements for lightweight, miniaturization and integration of electronic products such as mobile phones continue to increase, the gaps and pins between their components are getting smaller and smaller, but sometimes they need to be exposed to harsh application environments, such as many People take their mobile phones into wet bathrooms when taking a shower, and they also wear TWS headsets when swimming. Similar requirements require that the entire circuit board or most components must be protected so that they will not fail due to short circuit, corrosion or extrusion by external forces in harsh environments, and glue plays an irreplaceable role in this protection. .
Applications of different types of adhesives in the electronics industry
It is the most widely used adhesive in the electronics industry. Its bonding strength and mechanical strength are particularly excellent, its temperature resistance and chemical corrosion resistance are also unconventional, and its base material applicability is equally wide.
Depending on the product type, different products can be cured at room temperature or quickly cured by heating. After curing, they have extremely high bonding strength and mechanical strength, and have excellent temperature resistance and chemical resistance. It can be used for bonding and fixing, sealing protection, device protection, etc. of electronic product parts and structural parts.
It has good sealing and bonding performance and tolerant weather resistance. It can handle low temperatures to -50°C and high temperatures to 200°C, and can also be used under air pollution.
Depending on the product type, they have core properties such as excellent temperature resistance and insulation, as well as good sealing and bonding properties. It is widely used for fixed reinforcement, cavity sealing, waterproof protection, etc. of electronic components. It is also suitable for sealing, filling, bonding, and packaging in high-temperature applications, such as high-temperature kitchen appliances, thermoelectrics, and air purifiers.
The rapid implementation of emerging technologies such as 5G, smart homes, and new energy vehicles will inevitably lead to innovations in materials and manufacturing processes. As a traditional connection method, adhesives will become increasingly diversified and diverse following the development of modern industry. Functional. While injecting unlimited vitality into the electronic adhesive industry, it also poses new challenges!
