Description

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