PCB丝网印刷中怎样控制油墨的黏度和触变性

How to Control the Printing Ink Viscosity Degree and Thixotropy in the Silk Screen Printing of PCB

线路板在各种电子产品中的应用非常广泛，其质量和稳定性直接决定产品的质量。印制电路板（PCB）是电子丝网印刷中重要的印刷内容。在PCB印刷中，油墨的主要性能（如油墨的黏度和触变性）直接影响着PCB的印刷质量和生产速度。因此，在印刷中要注意熟悉和调控印刷油墨的黏度和触变性，保证PCB的丝网印刷的质量。

The printed circuit board is applied in various electronics products. Its quality and stabilities decide the quality of the product directly. Printed circuit board （PCB） has important position in the electronics silk screen printing. In the PCB screening printing, the main function of the printing ink （such as the printing ink viscosity degree and thixotropy） affects the PCB printing quantity and production speed directly. Therefore, in printing the printing ink viscosity degree and thixotropy must be controlled to make better quality production.
