Description

technical field [0001] The present application relates to the technical field of circuit board testing, and in particular, to a testing device and an assembly line for the impedance and diode characteristics of circuit board pins. Background technique [0002] Pin testing is a common test item in circuit board testing, which can determine the effectiveness of circuit board pins. The two main parameters for board pin testing are impedance and diode characteristics. The specific principle of testing the impedance and diode characteristics of circuit board pins is as follows: determine the power supply pins and ground pins of the circuit board; for each non-power supply pin, it is necessary to test the forward resistance and reverse direction to the power supply pin. resistance, and its voltage drop characteristics to the protection diodes of the power and ground pins. That is, four tests are required for each non-power pin. [0003] In the related art, the impedance and dio...
