Problems solved by technology

[0003] But so far, the direct writing process of microelectronic components is still limited to planar substrates
On a flat substrate, the usual direct writing manufacturing process is to place the flat substrate on a high-level storage table, use a micro-pen to move on the flat substrate according to the set program and eject conductive ink, and obtain a flat surface after subsequent processing. The finished direct-writing circuit on the substrate; on the curved substrate, the general method is to use scanning modeling to first obtain the parameters of the curved substrate, and then use the multi-axis platform to manipulate the micro-pen direct writing and other devices to obtain the direct writing circuit and electronic components on the curved surface. components; or adjust the distance between the direct writing pen tip and the substrate in real time through a high-precision distance sensor to realize the ability to directly write circuits and electronic components on curved surfaces; although the above methods are relatively mature, it is a pity that too many multi-axis platforms, Accurate scanning equipment, sensors and other devices will cause problems such as high cost, difficult maintenance, and complicated operation
