传统丝印的这些瓶颈问题正好是数码打印技术特有的优势。
These bottlenecks of traditional silk screen printing are the unique advantages of digital printing technology.
国内数码打印行业起步于2001 年，最早数码打印技术应用于包装、标记、广告、印花领域，最近十年数码喷印在3D 成形、陶瓷行业、医学血管成形等方面取得了飞速的发展。数码打印技术是运用的是加成法，与传统工艺流程相比，它可以做到简化流程，缩短生产周期的同时，减少物料浪费，提高能源利用率。在同样自动生产线生产的情况下，对比传统丝印生产线可以提高2倍甚至更高的生产效益。这也是PCB行业将数码打印看作pcb制造发展的新动力的最主要原因。
The domestic digital printing industry started in 2001. The earliest digital printing technology was applied to the fields of packaging, marking, advertising and printing. In the last decade, digital jet printing has made rapid development in 3D forming, ceramic industry and medical angioplasty. Digital printing technology uses addition method. Compared with the traditional process, it can simplify the process, shorten the production cycle, reduce material waste and improve energy utilization. In the case of the same automatic production line, compared with the traditional silk screen printing production line, it can improve the production efficiency by 2 times or even higher. This is also the main reason why the PCB industry regards digital printing as a new driving force for the development of PCB manufacturing.
具化到一个工艺来看，传统丝印阻焊工艺的工序至少有10道，丝网印刷需要印制网板，一版一用，还需要重复洗网，需要用到的洗型槽模具 一次性止血带 保定水处理设备 一次性止血带 保定空压机 北京真空泵网剂又是环保限制排废的化工品，并且，据我们了解，现在市面上最高精度的丝网生产线能够做到的阻焊桥的最小限值是2.5mil，市场主流精度在6mil左右。这对于日后芯片微小化的发展趋势来说，显然是一种限制。
From the perspective of a specific process, there are at least 10 processes in the traditional silk screen printing solder resist process. Screen printing requires printing screen boards, one plate for one use, and repeated screen washing. The screen washing agent required is also a chemical product that limits waste discharge by environmental protection. Moreover, according to our understanding, the minimum limit of solder resist bridge that can be achieved by the most accurate screen production line on the market is 2.5mil, The mainstream accuracy in the market is about 6mil. This is obviously a limitation for the development trend of chip miniaturization in the future.
