The test method is to press compressed air (or ammonia, fluorine, helium, halogen gas, etc.) into a container and check for leaks using the pressure difference between the gas inside and outside the container.
Laser 3D printing technology is an additive manufacturing, which usually uses powder coating to fill metal powder materials on the working platform, and then laser ablation and melting layer by layer to achieve the process of additive manufacturing from scratch.
The Han’s Laser high-precision testing machine is used for high-performance electrical testing of IC packaging substrates such as FC-CSP
The main difference between laser welding and argon arc welding is the difference in technical principles.
HFM-20H is a pulse fiber laser independently developed by Han’s Laser, designed using the MOPA solution
It is suitable for the protection of flat products such as mobile phones, computers, and glass.
English corner is a practice activity aimed at improving the oral proficiency of English users. As long as you enjoy English or use it in your daily life or work, attending an English corner is definitely a very practical choice.
This equipment is suitable for laser processing of wafer materials such as silicon, silicon carbide, silicon dioxide, gallium nitride, etc.
The average power ranges from 75W to 150W. The laser can switch freely between pulse mode and continuous mode.
At room temperature, the absorption rate of copper for near-infrared laser is less than 5%, while the absorption rate for green laser can reach 40%. The PG3 machine outputs a 532nm green laser with a peak pulse power of 1KW and a maximum single pulse energy of 3J.
