Laser marking technology in the application of the mobile phone manufacturing industry
Published : 2016-11-21 10:04:07

Material on the surface of the object can be removed point by point by the laser after Focusing as a sword .

Biggest advantage is that mark processing is non-contact processing, won't produce negative scratches and friction, also will not have extrusion and be crushed. So that the processing goods will not damaged. Due to more smaller the spot after the laser beam zoom again, the smaller the heating area , processing is precision, so it can do processing that cannot be completed by normal processing .

Laser processing with the help of modern CAD/CAM software, implement any form of plate cutting, the laser processing, not only the high processing speed, high efficiency, low cost, and also to avoid the mould replacement, shorten the production preparation time period.

In the applications of laser processing, laser cutting accounted for 32% of the market. Compared with other cutting methods , the biggest difference of Laser cutting is that it has the characteristics of high speed, high precision and high adaptability. At the same time ,it also has a small slot, small heat affected zone, good cutting surface quality, no noise when cutting, cutting seam edge vertical degree good, smooth cutting edges, cutting process is easy to realize automatic control, etc. When Laser is cutting board, it do not need mould, can replace some method that requires a complex large mould, cutting machining can shorten the production cycle and reduce the cost.

Laser technology and laser manufacturing equipment are applied to 70% of the links of mobile phone manufacture . Especially n recent years, high power, high-energy ultraviolet marking machine, deep uv and the development of ultrafast laser processing technology, promote the development of the intelligent mobile phone manufacturing technology. This is related with the nature of laser technology and the nature of the mobile phone precision manufacturing. On one hand, because the laser with high power density, good directivity and outstanding characteristics such as clean, efficient, environmental protection, the trend of the laser processing technology instead of traditional processing technology is increasingly accelerated, its micro processing advantages in laser welding machine, laser marking machine, laser cutting machine has obvious advantages. On the other hand, mobile phone processing, is the crystallization of a precision manufacturing technology, needs slightly processing and manufacturing equipment.

Laser drilling is one of the important mobile processing application technology. Laser focused spot can gather a wavelength scale, concentrated high energy in a small area , particularly is suitable for processing fine deep hole, the smallest aperture are only a few microns, hole depth and diameter ratio can be greater than 50 microns. In mobile applications , laser drilling can be used for PCB drilling, casing the receiver and the antenna, such as punching, headphones stiletto is high efficiency, low cost, small deformation, wide applicable scope, etc. Mobile phone within a slap big place focus on more than 200 parts, its processing and manufacturing technology is one of the most difficult manufacturing technology. Laser technique is an important technology to push forward the rise of China mobile phone manufacturing industry rapidly.
