Laser Marking Machine Development Trends and New Industry Applications
Lasers have been used for marking, etching and cutting since the mid-1960s. The world's first laser marking machine was developed in 1965 for drilling holes in diamond manufacturing molds, and the technology has since gained rapid development.
Despite competing with other technologies such as inkjet printing, lasers have proven to be a powerful, low-cost and repeatable marking technology. Importantly, the process is eco-friendly and does not require consumables (such as ink, cartridges and paper). While the development of laser marking technology has been rapid, manufacturers and users of laser marking machine systems are now looking for new routes to push the development of marking technology to meet new challenges and improve processing results.
Ceramics are one of the fastest growing materials in the field of laser processing, and this material is very important in the manufacture of semiconductor parts and circuit boards. Printed circuit boards (PCBs) are often called the "mother of electronic system products" and are a component used in almost all electronic products. Small changes in the development of PCBs have a great impact on market trends.
In recent years, the focus has shifted from the use of ceramics in traditional printed circuit boards (PCBs), which are made of plastic epoxy resins such as FP4. Compared with non-ceramic PCBs, ceramic circuit boards have excellent heat handling capabilities, are easy to implement, and provide excellent performance. However, many marking technologies, such as screen processing, are not suitable for ceramics. Ink marking of ceramics is cumbersome, requires several consumables, and is not wear-resistant. The brittleness and hardness of ceramics also make it one of the more difficult materials to mark.
Therefore, in recent years, laser marking machines have emerged as an alternative to ink printing technology, and many laser companies have developed systems that are particularly suitable for ceramic marking, such as diode-pumped solid-state UV lasers, as well as traditional CO2 lasers. I believe that in the future, more and more different types of laser marking machines will be applied to this industry to help enterprise
