AI Overview
UV Diode-Pumped Solid-State (DPSS) lasers are
a standard technology used for "cold marking" on sensitive materials such as silicone and plastic charger components. The UV wavelength (typically 355nm) creates high-precision, permanent marks without introducing significant heat, which prevents material damage. UV DPSS Laser Marking Applications
UV lasers use a "cold marking" process where high-energy photons break chemical bonds directly (photoablation), rather than melting the material with heat (thermal processing). This makes them ideal for delicate or heat-sensitive substrates.
Key applications relevant to your query include:
- Silicone Marking: UV DPSS lasers are widely used to mark information like QR codes, logos, and production dates on silicone wristbands, medical devices, and other silicone products.
- Charger and Electronic Component Marking: They are a primary method for marking information on a wide range of electronic accessories, including mobile phone chargers, power adapters, plastic cases, and PCBs (Printed Circuit Boards). The precision allows for clear, long-lasting marks on small, complex surfaces.
- Plastic Materials: The technology works well with many plastic and polymer materials (e.g., ABS, PE, PP, PBT) used in consumer electronics, providing high-contrast marks without burning or micro-fracturing the material.
Benefits of UV DPSS Lasers
- High Precision: The short wavelength (355nm) and small spot size result in a very fine, high-resolution mark.
- Minimal Heat Affected Zone (HAZ): The "cold processing" nature ensures that the area around the mark is not damaged or discolored by heat.
- Versatility: Capable of marking, engraving, cutting, or drilling various non-metallic materials, including glass and silicon wafers, in addition to plastics and silicone.
Manufacturers like DPSS Lasers, Inc. and RFH Laser produce integrated systems for these industrial marking applications.
