Abstract

The invention discloses a micro-resistance measurement equipment and measurement method. The resistance measurement equipment comprises a slide platform, a control device and a micro-resistance tester which is arranged on the slide platform and can move along three directions of X,Y and Z axes. One set or multiple sets of probes are arranged on the micro-resistance tester. According to the micro-resistance measurement equipment and measurement method, resistance value measurement can be rapidly, effectively and accurately performed on products, qualified and unqualified products can be distinguished, operation complexity of workers can be reduced and detection efficiency can be enhanced.

Description

technical field [0001] The invention relates to a resistance measuring device, in particular to a micro-resistance measuring device and a measuring method for measuring tiny resistances. Background technique [0002] In the field of electronic products, in order to ensure the yield rate of ex-factory products, it is necessary to measure the resistance value of the products after the production of the products is completed. The precision measurement of pure metal resistance value is generally measured by traditional four-circuit equipment, but in the process of measurement, the traditional measurement equipment does not accurately select the position of the measurement point, and the pressure of the probe is difficult to control, which may affect the measurement. Resistor value has an effect. Since the resistance value of the measured product is very small, only a few milliohms or a few tenths of a milliohm, in order to improve the measurement accuracy, a micro-resistance me...
