Problems solved by technology

This method usually uses a single beam of light for scanning processing of microchannels or micro-functional parts. There are also related studies that use multiple beams of light for parallel processing of micro-functional parts. The method of parallel processing can improve the processing efficiency to a certain extent, but compared with Efficient and intelligent preparation technology for integrated circuit chips such as computers and mobile phones. At present, the efficiency and intelligence of microfluidic chip preparation technology are relatively low, and continuous technological innovation and development are still needed.
