UV Laser Marking Machine
Features：
The UV laser marking machine uses a 355 nm wavelength UV laser with a "cold marking" method. The laser beam diameter is only 20 μm after focusing. The UV laser's pulse energy comes in contact with the material in the microsecond. There is no significant thermal influence next to the slit, so no heat damages the electronic component.
- With cold laser processing and a small heat-affected zone, it can achieve high-quality processing
- Wide applicable materials range can compensate for the shortage of infrared laser processing ability
- With good beam quality and a small focusing spot, it can achieve superfine marking
- High marking speed, high efficiency, and high precision
- No consumables, low cost and low maintenance fee
- The overall machine has stable performance, supporting the long-term operation
Application and Samples：
- UV laser marking of electronic products' LOGO, model, place of origin
- UV laser marking of food, PVC pipe, medicine packaging material (HDPE, PO, PP and so on); micro-hole drilling, diameter d≤10μm
- PCB laser marking, PCB laser depaneling, PCB laser singulation
- Removal of metal or non-metallic coatings
- Silicon wafer micro-hole and blind hole laser processing
- Laser marking of low-voltage apparatus and refractory materials

Mechanical structure：
Han’s Laser has recently launched the “Zhuguang Series” UV nanosecond lasers. This series is based on Han’s 15-year UV laser R&D experience and technology accumulation. Beam quality and extremely high laser stability have obvious cost-effective advantages, and can be widely used in precision processing fields such as laser marking, cutting and drilling.
At the same time, Han's Laser has completed its own business structure adjustment this year, and divided its business into three major business groups: general components and industry popular products, industry special machines, and extreme manufacturing. Self-sold upstream laser devices and supporting products, these core device sales business are completely independent from Han's own complete machine business, and are sold to various laser processing equipment manufacturers in the industry. At present, Han's Laser has launched the highly competitive "Zhuguang series" lasers to the laser equipment manufacturers in the market, announcing that its laser component sales business has taken the first step. It is understood that in the follow-up Han's Laser will also launch core laser devices such as ultraviolet and ultrafast lasers, pulsed fiber lasers, medium and low power CO2 lasers, and chillers to the market.
