Nowadays, smart phones are moving towards thinner and lighter, and mobile phone camera modules are becoming smaller and smaller. How to process such micro components has become an important link that hinders development. However, laser processing technology is an important tool in the field of micro-precision processing, with high processing accuracy, which can process various types of components, especially in the field of cameras.
The PCB circuit board in the camera module of the mobile phone is a combination of FR4 and FPC, and some of them use pure hard boards or soft boards. The application of laser technology to this sector is mainly for FR4 laser cutting and FPC laser cutting technology. Another laser process technology is to perform two-dimensional code laser marking technology on FR4 or FPC.
The laser compliance technology is mainly applied to the surface marking of the camera chip, usually marking the company's logo and product related information, playing the role of brand promotion and downstream link management, and easy operation. With the advancement of products and the introduction of internal traceability systems, the laser marking technology of 2D codes on chip surfaces has become more and more popular.
There is a link conductive module on the bracket, and the conductive metal module inside the area is small and very thin. The laser welding technology can effectively strengthen the welding firmness and improve the conductive performance without damaging it.
The glass in the camera module is ultra-thin glass. Not only can it not be broken during processing, but also its strength and chipping rate must be ensured. The advantage of using laser processing technology is that the processing speed is fast, the chipping is small, and the yield rate is small. high.
The laser marking technology in the lens and motor is mainly a two-dimensional code smaller than 0.5*0.5mm on the surface or edge mark, which plays the role of anti-counterfeiting and traceability.
A small camera module has so many laser process technologies applied to it, which shows the importance of laser technology as an advanced process technology.
