Application of UV light curing technology in smart phones

Dec 03, 2021

With iPhones and iPads taking the world by storm, MID products with ultra-thin, touch-screen, and smart systems have become the latest consumer favorites. In the process of designing and manufacturing mobile phones, the combination of alloy and engineering plastics has become a new trend. In the process of production and assembly, traditional threads and buckles are already very satisfying to achieve ultra-thin, ultra-light, three-dimensional and beautiful features. In order to achieve no gaps and flat and thin appearance points, more and more adhesives are used in the assembly process. Connect and fit components. UV LED light curing technology meets the requirements of short-time bonding and curing.

 The locations of UV LED curing machines for smartphones are as follows:

1. Mobile phone screen and mobile phone frame bonding

2. Adhesion of mobile phone shell

3. Adhesive and fixed side buttons

4. Camera window positioning

5. Paste the LOGO

6. The cover of the sound cavity box in the smart phone

7. Between the smartphone FPC antenna and the case

8. Between HOLDER and FPC on the camera module (FPC bending area)

9.Fixed the connection of the flat motor of the mobile phone.

10. Mobile phone motherboard fixed

 

 The above and so on gradually adopt the method of glue dipping, and some of them use double-sided adhesive, hot melt adhesive, UV glue, instant glue, silica gel and other glues, and most of them use UV point light source technology. However, since mobile phones are consumer products, according to the EU Directive 2009/425/EC, the organotin compounds concerned include tributyltin, triphenyltin compounds, and dibutyltin and dioctyltin compounds, of which the formal start time limit for the first two is 2010 July 1st, and the latter two time is January 1, 2012. The above four organotin compounds are widely used in consumer products. In the actual production process, 10% to 20% of the world's tin production is used to synthesize organotin compounds. This shows the wide range of applications of this substance. . The reason for the ban on organotin is because organotin compounds are harmful to organisms, causing diabetes and hyperlipidemia. UV curing equipment with UV glue can not only be used on organotin compounds but also other related materials.
