Abstract

The present invention is applicable to the technical field of inductance consistency detection, and provides a 3D integrated LC filter multi-layer substrate manufacturing consistency detection device and system, comprising: a circuit board with a preset pattern, the first area of ​​the preset pattern includes The inductance pattern corresponds to the position of the inductance in the 3D integrated LC filter; the capacitor C1 is set in the second area of ​​the preset pattern, and one end of the capacitor C1 is connected to the position of the inductance pattern through a wire, and the capacitor C1 communicates with the inductance L1, The other end of the capacitor C1 is grounded. The LC series resonant notch circuit formed by the inductor L1 and the capacitor C1, by measuring the notch frequency of the LC series resonant notch circuit, can classify the consistency of the multilayer substrate of the 3D integrated LC filter to solve the problems in the prior art The processing consistency of the actually generated three-dimensional inductor integrated in the multilayer substrate cannot meet the requirement of the consistency of the electrical characteristic index of the 3D integrated LC filter.

Description

technical field [0001] The invention belongs to the technical field of inductance consistency detection, and in particular relates to a 3D integrated LC filter multilayer substrate manufacturing consistency detection device and system. Background technique [0002] The 3D integrated LC filter includes three-dimensional inductors and multi-layer ceramic capacitors (Multi-layer Ceramic Capacitors, MLCCs). Among them, the three-dimensional inductors are integrated in the multi-layer substrate, and the MLCC is mounted on the surface of the multi-layer substrate using three-dimensional wiring technology. In the disk, the 3D integrated LC filter completely solves the problems of large size, poor assembly consistency and low production efficiency of traditional LC filters. Since the 3D integrated LC filter is designed without debugging, the capacitance accuracy of the MLCC mounted on the surface pad of the multi-layer substrate is as high as ±0.03pF. Therefore, the consistency of t...
