以丝网印刷方式印刷电子监管标签的研究

Screen Printed Resonant Tags for Electronic Article Surveillance Tags

在塑料薄膜上采用丝网印刷方式印刷谐振标签,已经成为低成本电子监管标签的生产方式。以印刷方式生产的谐振标签,可以方便地在印刷过程中通过改变感应器和电容器的印刷长度和尺寸来改变谐振标签的谐振频率。谐振标签的质量因子(Q)主要取决于印刷感应器的薄膜阻抗,印刷方式生产的谐振标签能够获得的最大Q值约为45。由于这种谐振标签能够用卷筒进料的塑料薄膜进行印刷,因此,各种谐振频率的电子标签都能够通过这种印刷方式进行大批量低成本生产。

Screen printing has been employed to print resonant tags on a plastic film for using as a low cost electronic article surveillance tags. The resonant frequency of the printed resonant tags can be tuned by simply varying the lengths or sizes of printed inductors and capacitors. The quality factor （Q） of the printed resonant tags strongly depends on the sheet resistance of the printed inductive patterns. The maximum Q factor of printed resonant tags attained was about 45. Since this resonant tag can be printed roll-to-roll on plastic films, a number of tags with various resonance frequencies can be mass produced at a lower cost.
