Watch gears. A precision watch usually contains hundreds of complicated gears. These gears must fit together perfectly to achieve precise timing functions. The increasingly fierce competition in the high-end precision watch market is urging watch manufacturers to seek more effective manufacturing processes to achieve more precise parts processing with higher output and faster processes. Ultra-short pulse laser pointer technology can realize high-speed precision cutting of any material without thermal damage, which eliminates expensive and time-consuming subsequent processing. Therefore, ultra-short pulse laser technology is pushing the precision watch industry forward.
Semiconductor probe card. For any micro-processing platform, the manufacture of small holes on a semiconductor probe card is one of the most difficult and technically challenging applications. Probe cards are test sockets for thousands of micron-sized wires and connectors on integrated circuits. A single probe card can require 50,000 micro-holes in an area of 25mm×25mm, and the precision of the micro-holes is required to be micron level. The new design of semiconductor probe cards requires sockets of different shapes, including square and rounded shapes. The ultra-short pulse laser platform can process these micro-holes with extremely high speed and precision, significantly shortening the processing time and improving the quality of parts.
Micro slot. For many applications, high-precision microgrooves are essential. For example, in microfluidic channel processing applications, the size of the groove must be able to separate fluids at the molecular level, transport the fluid to be extracted and tested, and filter out all other fluids.
“Dark mode is attractive and requires low power consumption for this application. But without any tricks, the dark mode green laser pointer will be useless because the light is trapped in the nanoparticle array and cannot be left”, The research scientist added. “However, using the small size of the array, we have found a light guiding path. Pointing to the edge of the array, the nanoparticles begin to behave more and more like ordinary antennas, radiating to the outside world,” said the PhD student. The research team used nanofabrication facilities and clean room equipment at the National Research Center to conduct the research.
