Description

Technical field:

[0001] The invention relates to the technical field of circuit board detection, in particular to a high-precision circuit board detection device. Background technique:

[0002] The principle of circuit board testing equipment is to connect the pads or test points on the circuit board through metal probes, and obtain typical values ​​such as the voltage value and current value of the test circuit when the circuit board is powered on, so as to observe whether the test circuit is conductive. If it is normal, it can quantitatively measure resistance, capacitance, inductance, crystal oscillator and other devices, perform functional tests on diodes, triodes, optocouplers, transformers, relays, operational amplifiers, power modules, etc., and perform functional tests on small and medium-sized integrated circuits , such as all 74 series, Memory class, common driver class, exchange class and other ICs. The circuit board inspection equipment finds defects in the manu...
