[0005] 3. Factor analysis: due to too many resonator parameter factors, a lot of information will be lost by judging the correlation of a few parameters, and it is difficult to guarantee the influence of other factors
As the resonators are gradually assembled into filters, there will eventually be some remaining resonators that cannot be matched

A filter consistency quality control method based on a resonator assembling technology comprises the following steps of step1, testing resonator parameters including a frequency, a resistance, a static capacitance, a dynamic capacitance and an inductance; step2, using a process quality consistency model to predict filter quality, entering into a next step when the quality reaches a standard, replacing a resonator when the quality does not reach the standard, and repeating the step2; step3, assembling the resonator; and step4, testing filter performance, entering into the next step when the performance reaches the standard, and returning to the step 2 if the performance does not reach the standard. In the invention, comprehensive analysis of multiple parameters of the resonator can be performed, and multiple variables with a intricate relation are resolved to a few comprehensive factors through dimensionality reduction; performance data of the resonator which is assembled into a filterbefore process assembling can be predicted; and a matching result can be predicted before matching and feedback can be performed.
Description
technical field [0001] The invention relates to the technical field of filter production, in particular to a filter consistency quality control method based on a resonator assembly process. Background technique [0002] The resonator assembly process takes a long time to assemble, which has a great impact on product quality. At present, the means of process quality control in the resonator assembly process are all inferred from the experimental results, and the following methods are basically used: [0003] 1. Manual combination: Rely on manual assembly of resonators into filters, test the performance of the installed filters through a network analyzer, and randomly replace crystals according to the performance images generated by the test. [0004] 2. Rely on experience: After manually matching and combining filters, rely on experience to observe the changes in the image waveform of the network analyzer. Through multiple practices, find out the possible influence of a sing...
