摘　　要：结合丝网印刷墨层厚度的各主要影响因素,分析了理论墨层厚度和实际墨层厚度与网版目数的关系,建立了网版静态及受压变形两种状态下的墨层厚度计算模型,拟合了网版目数和实际墨层厚度之间的关系曲线,并选择合适的丝网印刷工艺参数,印刷制作了两款无源RFID标签天线,通过天线电阻值的波动情况分析,论证了用丝网印刷工艺制作无源RFID标签天线的品质可靠性。The relationship between the screen mesh and the theoretical and practical ink film thickness was analyzed based on the main influencing factors of the ink film thickness by screen printing. A calculation model for the ink thickness was established based on the screen under static and compressive deformation. The relation curve between the screen mesh and the ink film thickness was fitted and the suitable printing craft parameter was chosen to print two kinds of RFID tag antennas. The fluctuation of the antenna resistance was analyzed to demonstrate the reliability of the passive RFID tag antenna manufactured by screen printing technology.
