目前PCB行业传统工艺面临的瓶颈主要在这样几个方面：
At present, the bottlenecks faced by traditional processes in PCB industry are mainly in the following aspects:
一、现有PCB 行业线路、阻焊、字符印刷一般为丝网印刷，由于丝网印刷需要制版，制版后在实际使用过程中需要对色、调版等，虽然在大批量生产中得到广泛应用，但在小批量生产中却费时费力，而且需要的准备时间长、容错率低。
1、 The existing PCB industry circuit, solder resist and character printing are generally screen printing. Since screen printing requires plate making, color matching and plate adjustment are required in the actual use process after plate making. Although it is widely used in mass production, it is time-consuming and laborious in small batch production, and requires long preparation time and low fault tolerance rate.
二、虽然传统丝印现在全自动生产线，但由于步骤多，而每一步骤都需要配备人工抠细组，那么实际生产中还是处于一个半人工的这样一个状态。
2、 Although the traditional silk screen printing is now a fully automatic production line, due to many steps, and each step needs to be equipped with manual matting group, it is still in the state of one and a half manual in actual production.
三、由于整个丝印工艺采用的减成法的原阳雕刻 手套生产设备 果树反光膜 北京纯水设备 保定网站制作 排水槽模具理，生产过程中使用到的一次性物料菲林，显影剂，洗网剂，等等。导致传统工艺废料多，排污排废严重，对公众环境的危害也很大。
3、 Due to the principle of subtraction method adopted in the whole silk screen printing process, the disposable materials used in the production process include film, developer, screen washing agent, etc. As a result, there are many traditional process wastes, serious sewage discharge, and great harm to the public environment.
