532 green laser scribing, cutting and marking solutions on silicon wafers

532nm green laser can avoid bursting when drilling silicon wafers

Silicon wafer micro-holes, blind hole processing, green lasers are all handy

Silicon wafers are purified from silicon and made into long silicon ingots, which become the material of quartz semiconductors for manufacturing integrated circuits. After photo-making, grinding, polishing, slicing and other procedures, the polysilicon is melted and pulled out of the single crystal. The silicon ingots are then cut into thin wafers to form the final product.

The scribing and marking process of silicon wafers is complicated, but it is a simple task for RFH green lasers. Using RFH's green laser marking can contract a series of tasks in production, and all the marking, cutting and marking can be solved by debugging. In addition, the accuracy and smoothness of the two steps of scribing and cutting can be guaranteed, and the characters and patterns can be clearly engraved on the silicon wafer during marking without being easily blurred.

The watch manufacturer, Manager Zhou, recently purchased a batch of green lasers from RFH that are mainly used for scribing, cutting and perforating silicon wafers of watch mirror materials.

With 13 years of ingenuity, the Expert Ⅱ 532 green laser developed and produced by RFH has a wide repetition frequency range from single pulse to 200kHz; it strictly guarantees superior beam quality (M²<1.3) and perfect spot characteristics in all frequency ranges. Ovality>90%), which is very suitable for the scribing and marking of silicon wafers; in addition, the pulse width of the green laser is <35ns@30k, and the heat-affected area during processing is small, and there will be no scorching or deformation. Circumstances; The unique Q-switching control technology is suitable for various laser application control needs; the use of all-digital intelligent power control technology is simple to operate and convenient for remote monitoring.

 "±0.002mm high precision", "high stability", and "cost-effective" are the core advantages of RFH green lasers

Rigorous production system and dust-free production workshop are the cornerstones of forging high-quality green lasers

From procurement-pre-production quality inspection control-rigorous assembly process-finished product testing-warehousing quality inspection-pre-delivery inspection-after-sales service, each level is checked to ensure stable quality and consistency of equipment parameters with actual operating parameters. The clean production environment ensures that all electronic components are produced dust-free and free from pollution. This is the reason why the service life of RFH brand lasers is better than that of peers. Professor-level teams at home and abroad independently research and develop special power control systems for lasers to reduce the failure rate

There is a one-to-one correspondence between the power supply and the laser. The stability of the power supply control system determines whether the laser can maximize its performance during operation. RFH has the advantages of independent research and development of power supply technology, which can update the function modules of the power control system in time, and improve the function modules according to the needs of the laser. 12 years of R & D technology accumulation, domestic and foreign experts, doctoral level R & D team. This is a solid backing for the stable operation of RFH's entire laser system.
