The Prospect of Precision Manufacturing is Wide and Laser Micro-Processing is Potential to Develop
In recent years, mobile phones, tablets and other consumer electronics products have shown explosive growth. The huge growth rate and stricter quality requirements have promoted the technological innovation of manufacturing process. In this context, laser technology with obvious advantages has become a new favorite of manufacturing industry.
Although laser processing has great advantages in many fields, the overall industrialization time is not long. Compared with the traditional machining technology which has experienced more than 200 years of precipitation and has penetrated into all walks of life, the share of laser processing is still very small. There are two main reasons. On the one hand, the operation cost, the traditional process can achieve batch synchronization, such as punching with a punch, a die can be four, six or more holes at the same time, and the laser must be cut one by one, in contrast, the efficiency of the laser is low, and the production cost is high. On the other hand, the cost of investment, laser equipment prices are far higher than the traditional machine-added equipment, single investment is too high and the expected return is insufficient, so most processing enterprises will not choose laser equipment as the main productivity.
With the application of picosecond laser and femtosecond laser, many problems in laser cutting in the past have been alleviated or solved, including cracks, edge collapse, blackening of cut surface and so on. At the same time, electronic products are becoming more and more miniaturized, which requires higher precision of micro-area. Traditional machining technology is becoming more and more difficult to meet the requirements, while the small laser spot can easily complete the task of high precision processing, such as the small aperture below 50 micron is where the laser can show itself.
Despite the small proportion of laser microfabrication applications, this trend is bound to be good. For example, Apple's 5G antenna is now all cut by picosecond laser. In fact, laser and traditional technology are complementary rather than completely substituted. Laser has incomparable advantages in processing small areas with high dimensional accuracy. Therefore, although the laser market share is small at present, there must be a lot of room for growth in the future.
