[Abstract]:This research and development example subject, focus transmission line characteristic impedance parameter.Three factors are extracted as independent variables to monitor the quality stability of characteristic impedance parameters in time.The characteristic impedance control of flexible circuit board (FPC) is an important part of realizing the performance of flexible circuit board.The research on how to solve the characteristic impedance control in actual production accurately and quickly has definite engineering significance.This work focuses on the study of the influence of FPC technology in the production process on the characteristic impedance control. Combining with the data produced by different materials and different structural conditions under the production mode, the multi-group production experiments are designed pertinently.By comparing the simulation calculation of characteristic impedance (dependent variable) with the actual indirect measurement, it is verified that the following results are obtained: 1) the characteristic impedance line thickness (H) has direct influence on the characteristic impedance of FPC.The parameters of independent variables are as follows: the line width of characteristic impedance of FPC is directly affected by the line thickness of characteristic impedance.The parameters of independent variables considered are as follows: the thickness of the mask (T) overlaid on the characteristic impedance line of FPC has a direct effect on the characteristic impedance of FPC, and the parameter of independent parameter is: the thickness of the mask layer is T ~ ((1)), and the parameter of the independent parameter is: the thickness of the mask layer is T ~ ((3)).It is concluded from the above experiment that (according to the descending power of the contribution priority, the characteristic impedance line thickness, the characteristic impedance line width, the mask thickness and the thickness of the mask layer) are the important factors affecting the characteristic impedance of FPC, and the structural requirements and different customer requirements are considered.These factors need to be properly deployed.
