新赛道 新商机 新希望——变化中的网版与新赛道网版(十三)

Changing Screen Printing Plate and Screens on the New Track(Part 13)

网版印刷技术新赛道中的新网版,是阶梯网版、立体网版和微细印刷网版。网版印刷技术所服务的范围太过宽泛,不同的应用领域要注重适用和实用原则。高目数的不锈钢丝网加超高解像力的丝网感光材料制成的优质丝网网版,并不能完成SMT技术中锡膏淀积的网版印刷作业,取而代之的是激光切割钢版或电铸钢版的新镂空版。

The new plates of screen printing technology in the new track is the ladder screen,three-dimensional screen and micro-printing screen.The scope of screen printing technology is too broad,and diff erent application fi elds should pay attention to the application and practical principles.The high-quality wire mesh plate made of high mesh stainless steel wire mesh and ultra-high resolution screen sensitive material can not complete the screen printing operation of solder paste deposition in SMT technology,instead of the new hollow plate of laser cutting steel plate or electric casting steel plate.
