Applications
The LDl projection imaging lens based on DMD is a DMD series photolithography lens suitable for fields such as solder protection, 3D printing, PCB circuit (HDl,multi-layer boards, soft boards, circuit boards, lC carrier boards, etc.) exposure process.After applying this technology to the PCB exposure process, compared to traditional mask exposure, it can save time required for multiple processes such as plate making and process validation, shorten the process cycle, and significantly improve the production efficiency of PCB production. It can also solve the problem of alienment error caused by expansion and contraction, as there is no need for a mask, Therefore, it can optimize the alignment error caused by thermal expansion, avoid defects caused by mask defects, and improve the accuracy and output of PCB manufacturing, improve the stability of mass production, and better reduce production costs and ensure product quality.
