Description

technical field [0001] The invention relates to the field of microfluidic technology, in particular to a microfluidic chip printing system and a printing method. Background technique [0002] Microfluidic chip is a new interdisciplinary field and an important development frontier in many fields such as analytical science, micro-electromechanical processing, life science, chemical synthesis, analytical instruments and environmental science in the new century. [0003] The processing technology of microfluidic analysis chips originated from the microfabrication of semiconductor and integrated circuit chips, but the processing size of the chip channel is much larger than that of large-scale integrated circuits. The size of the chip is about a few square centimeters, and the width and depth of the microchannel are on the order of microns. On the other hand, the selection of chip materials, the design of microchannels, the surface modification of microchannels and the fabrication...

Problems solved by technology

[0004]In the prior art, in the microfluidic chip processing technology, there are mainly methods such as laser engraving, chemical etching, and photolithography. These methods have their own advantages and disadvantages. The disadvantages are complex operation, long processing cycle, material selection, large channel roughness, and poor repeatability, and it is difficult to produce in batches, so it is difficult to be used as a general and effective chip processing method

With the development of modern numerical control micromachining technology, its processing accuracy and scale can meet the technical requirements of microfluidic chips, but the existing numerical control micromachining equipment is not designed for the design and processing of microfluidic chips , causing unnecessary waste and destruction of materials in application

[0005]Therefore, there is still a lot of room for development in the existing technology
