Ultrafast Lasers - Precision Manufacturing
Ultrafast laser is a new generation of mainstream technology in the field of precision processing: ultrafast laser refers to a pulsed laser with a pulse width of output laser at the level of picoseconds (10-12 seconds) or less than that of picoseconds. Depending on the pulse width of output laser, Ultrafast lasers can be divided into picosecond lasers, femtosecond lasers, nanosecond lasers, etc. As an emerging material processing technology, ultrafast laser is one of the most important technical directions in the field of energy laser, and has significant advantages in processing.

Typical Application - Semiconductor Wafer
With the development of innovative applications such as automotive electronics and 5G, China's semiconductor chips are developing rapidly. The semiconductor industry chain mainly focuses on silicon wafer preparation, wafer manufacturing, packaging and testing. With the sharp increase in wafer integration, the wafer tends to become lighter and thinner. The traditional knife wheel cutting has certain limitations. It directly acts on the thinned wafer, which will cause greater thermal impact and cutting defects, such as Defects such as chipping, cracks, passivation, and metal layer lift-off, therefore, it is necessary to adopt a laser process with small processing heat impact, high processing accuracy and high efficiency. Celestica Laser has a comprehensive layout in the semiconductor industry, providing you with solutions and industry-specific machines covering the back-end process of semiconductor wafers, such as wafer bonding, wafer grooving, wafer cutting, wafer splitting, wafer edge cleaning, wafer A variety of laser application technologies such as wafer inspection and sorting, wafer marking, etc., meet the different needs of semiconductor companies.

Typical Application - Display Touch
The transfer of 3C products such as mobile phones from mobile terminals to smart terminals means that the functional requirements of products have increased, and mobile phone modules have become highly integrated and thinner. This trend brings new materials and high-precision requirements that make laser ultra-fast processing have significant advantages. In 3C and 5G-related industries, materials such as glass and ceramics are changing in the direction of "harder" and "more brittle". For the processing of brittle materials and flexible materials, laser micro-nano processing has replaced traditional processing methods to achieve laser cutting, drilling and so on. The processing technology of hole, welding and marking can achieve double improvement of processing efficiency and effect.
