　　PCB is one of the indispensable and important processes during the manufacturing process of printing circuit boards. In order to obtain the preservation of image replication, the ink must have good stickiness and appropriate tactile. The so -called viscosity is the internal friction of the liquid, which is expressed in

　　Under the action of external force, one layer of liquid slides on the other layer of liquid, and the friction force applied by the inner layer of liquid. The mechanical resistance encountered in the thick liquid slide is large, and the liquid resistance is less resistant to the liquid. The unit of viscosity is performed. In particular, the temperature should have a significant effect on viscosity.

　　Tentority is a physical characteristics of liquid, that is, its viscosity decreases in the stirring state, and after static, it quickly restore its original viscosity characteristics. By stirring, the effect of tactile degeneration continues for a long time, which is enough to re -form its internal structure. To achieve high -quality net printing effects, the touch of ink is very important. Especially during the scraping process, the ink is stirred and then liquid. This effect is accelerating the speed of the ink through the speed of the mesh to promote the ink separated by the original network cable evenly. Once the scraper stops exercise, the ink returns to the static state, and its viscosity will quickly return to the required data
