PCB丝网印刷中怎样控制油墨的黏度和触变性

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

电路板在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)是电子丝网印刷中的重要印刷内容。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油墨的黏度与触变性,保证PCB丝网印刷的质量。

The circuit plank is in various electronics product of applied very extensively, its quantity and stabilities decide the quantity of the product directly. Printed circuit board（PCB） is its important printing contents in the electronics silk screen printing.In the press in the PCB, the main function（if the printing ink glues the degree and touches to change function） of the printing ink affects the PCB printing quantity and produces the speed directly. Therefore, at in the press to notice to acquaint with and adjust to control to print the printing ink to glue the degree and touch to change function, the quantity of the silk screen printing of the assurance PCB.
