Precision manufacturing is promising and laser micromachining is poised to take off

In recent years, consumer electronic products such as mobile phones and tablet computers have witnessed explosive growth. The huge growth rate and more stringent quality requirements have promoted the technological innovation of manufacturing technology. Against this background, lasaer pointer technology, which is obviously advantageous, has become the new favorite in manufacturing industry, and this seemingly high-end technology has taken the step of industrialization.

Although laser processing has great advantages in many fields, but the overall industrialization time is not long, compared with more than 200 years of precipitation, has already penetrated into all walks of life of the traditional machining technology, laser processing share is still very small. OFweek spoke with zhu xiwen, deputy general manager of kunshan yunke precision industrial technology co., LTD., about the application of laser technology in the micro machining market.

“There are two main reasons for the small share of lasers in the micromachining market,” zhu said. On the one hand, there are operating costs. Traditional processes can achieve batch synchronization, such as punching with a punch press. A die can be punched with four, six or more holes at the same time. On the other hand, the investment cost, the price of laser equipment is much higher than the traditional machine and equipment, single investment is too high and return is expected to be 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 existing in laser cutting in the past have been alleviated or solved, including cracks, edge breakage and blackening of the cutting surface. At the same time, electronic products are gradually moving towards miniaturization and miniaturization, with higher precision requirements for small areas. Traditional machining techniques are becoming more and more difficult to meet the requirements, while small laser spots can easily complete the task of high-precision processing, for example, small aperture below 50 microns is where the laser can fully display its capabilities.
