Problems solved by technology

[0003] However, due to the centralized power supply method used in the SMD component circuit, if you need to disconnect the power supply of one of them, you can only disconnect the circuit by removing the op amp chip. Repeated tests may directly lead to damage to the pad or chip.

Abstract

The invention discloses a multi-pass pad device applied to a PCB circuit board. The formed graph is also an axisymmetric graph; the main pad is used for connecting the output end of the power supply circuit in the PCB circuit board, and the auxiliary pad is used for connecting the input end of the load circuit in the PCB circuit board. The present invention controls the power supply of the corresponding load circuit by controlling the connection or disconnection of the auxiliary pad and the main pad, which is more convenient for circuit testing. At the same time, the auxiliary pad is arranged around the main pad with the symmetry axis of the main pad as the symmetry axis, which saves the space of the PCB circuit board and prevents electromagnetic interference from forming a current loop in the actual circuit later.

Description

technical field [0001] The invention relates to the technical field of circuit debugging, in particular to a multi-channel pad device applied to a PCB circuit board. Background technique [0002] In the multi-parameter acquisition and debugging test of multi-op-amp circuits, it is often necessary to control the power supply on and off of each circuit, so as to independently test, collect and calculate the power consumption of op-amps in each independent circuit. [0003] However, due to the centralized power supply method used in the SMD component circuit, if you need to disconnect the power supply of one of them, you can only disconnect the circuit by removing the op amp chip. Repeated tests may directly lead to damage to the pad or chip. . Contents of the invention [0004] The invention proposes a multi-pass pad device, which is used to connect the power supply circuit and the load circuit in the PCB circuit board, and controls the power supply of the corresponding loa...
