Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or t...

Abstract

The invention relates to the technical field of LCR testing, and discloses a multi-channel high-precision LCR testing system. Themulti-channel high-precision LCR testing system comprises a plurality of scanning cards which are connected with a product to be tested and have the same structure, and measuring cards which is arranged opposite to the scanning cards, the plurality of scanning cards are connected with the measuring card through a back connecting plate, the scanning cards are used for realizing channel switching, the measuring cards are used for realizing an LCR test, the back connecting plate is used for realizing signal transfer, the back connecting plate is connected with a main control board, and the main control board is used for realizing signal control on the measuring cards and the scanning cards. According to the system, synchronous measurement of a plurality of measuring plates is realized, the measuring plates can be randomly corresponding to one scanning plate or a plurality of scanning plates, and the application is flexible.

Description

technical field [0001] The invention relates to the technical field of LCR testing, in particular to a multi-channel high-precision LCR testing system. Background technique [0002] LCR inductors (L), capacitors (C) and resistors (R) are widely used in electronic products as basic components. With the continuous development and improvement of the technology and performance of electronic products, the requirements for the detection technology of components in related domestic industries are also constantly improving. The LRC tester is an instrument used to measure the corresponding physical parameters of capacitance, resistance and inductance components. Compared with commonly used multimeters, LRC testers not only have higher measurement accuracy, but also can measure various parameters of components, such as impedance, quality factor and so on. However, since the existing LRC tester has only one pair of test heads, it can only be connected to the two poles of one component...
