Features of pcb laser marking

● Using high-performance UV laser, the laser beam quality is superior, bringing users exquisite and beautiful marking effects.

● 355nn output wavelength, high photoelectric conversion rate, beautiful engraving effect, excellent marking effect, good touch feel, and strong anti-counterfeiting properties.

● Laser beam base film, short pulse width, high peak power, high repetition frequency, small heat-affected area, avoid deformation, damage or scorching of the processed material, and high yield.

● The marking speed is fast and the efficiency is high; the whole machine has stable performance, small size, low power consumption, and can run continuously and stably for 24 hours.

● Suntop Fiber Laser Marking Machine is subject to strict aging tests and continuous 24-hour laser beam output before leaving our factory to ensure 100% machine stability.

Details of pcb laser marking

Advantages of pcb laser marking

● Non-contact processing, no damage to the workpiece

Marks can be printed on any regular or irregular surface, and the workpiece will not produce internal stress after marking, ensuring the original accuracy of the workpiece. There is no corrosion on the working surface, no "tool" wear, no toxicity, and no pollution. .

● Low operating cost and easy maintenance

The marking is formed in one step, the marking speed is fast, the energy consumption is low, and the operating cost is low.

● Wide adaptability to materials and good durability

It can mark a variety of metal, non-metal and alloy materials with very good durability, wide application range and the mark is not easy to erase.

● Flexibility and high reliability

Printed content includes serial codes, batch numbers, barcodes, QR codes, logos and patterns, etc. The performance is stable and reliable and can work continuously around the clock.

Application materials of pcb laser marking

It is suitable for almost all materials. Widely used in metal (all metals such as iron, copper, aluminum, magnesium, zinc, etc.), glass, crystal, PCB, plastic, fiber, paper, paint, silicon wafer, LCD, polyamide, wire, plug and other polymer materials.

Application industry of pcb laser marking

Especially suitable for the high-end market of ultra-fine processing, surface marking of packaging bottles of cosmetics, medicines, food and other polymer materials, marking and scribing of flexible PCB boards; micro-hole and blind hole processing of silicon wafers; LCD liquid crystal glass QR code marking, glassware surface drilling, metal surface coating marking, plastic buttons, electronic components, gifts, communication equipment, building materials, etc.
