A brief introduction to electronic adhesives

The history of adhesives can be traced back 200,000 years to Italy, where a tar adhesive made from birch bark was used, but no artificial adhesives were used until the 19th century. In 1962, the first synthetic cyclized rubber appeared in the United Kingdom. Since then, the adhesive industry has officially entered a period of rapid development.

In recent years, the adhesive market has witnessed strong growth momentum. With the gradual shift of the production and consumption focus of the global adhesive market to Asia, the huge Chinese market has gradually become a competitive place for each major adhesive manufacturer.

With the support of the national policy and the 14th Five-Year Plan, under the background of the stable development of the macro-economy, Chinese adhesive manufacturers for consumer electronics will continue to get rapid development by improving their product technical level and increasing promotion efforts through independent innovation.

Adhesives for consumer electronics are subdivided into application varieties of adhesives, which are widely used in various electronic products such as smartphones, tablets, and wearable devices. Adhesive performance requirements of different application products are also different, and the demand and price also have certain differences. Driven by 5G, artificial intelligence, and the Internet of Things, the requirements for electronic products are becoming more and more stringent. Miniaturization, lightweight, and multi-function have become the development trend. Accordingly, electronic components also tend to be integrated, which requires the assembly of components and the subsequent production process to be more precise, and naturally puts forward higher adaptability requirements for the adhesive used.

Take a mobile phone, the representative product of consumer electronics, for example, an ordinary smartphone, with at least more than 160 glue points. Different from the cumbersome mechanical connection, the adhesive bonding method can not only effectively reduce the weight of the product, so that the design is more concise and practical; And can be a mechanical connection, the physical connection can not reach the narrow gap filling, sealing, and protection. Other devices, such as TWS headphones, smart watches, VR devices, and other consumer electronic products, with the addition of adhesives, more widely replace the traditional process and play an increasing role, to perfectly achieving their functional needs. For example, camera lenses usually use low shrinkage optical transparent adhesive, with nano-filling material bonding, so that the pressure on the lens is relatively small, will not affect the quality of optical components; For example, in many consumer electronics, speakers and camera modules are almost all glued together with adhesives. The following describes the common adhesive application scheme of consumer electronics.

• PCB integrated circuit carrier board three anti-coating
• Polyurethane three anti adhesive
• Acrylic UV three anti adhesive
• Silicone triple anti paint
• The FPC/BTB connection is fixed
• UV adhesive
• UV light/moisture double curing adhesive
• RTV silicone rubber
• Screen/cover plate and other structure bonding/sealing
• PUR hot melt adhesive
• UV adhesive
• Polyurethane/epoxy structural adhesive
• Type-C and other parts/modules assembly
• PUR hot melt adhesive
