KUKA robotic circuit board repair

For "online" measurement, the requirements consider that the components under test are affected by other parallel branches, and the measurement results should be analyzed and judged against the schematic diagram.

The "offline" measurement requirement requires the components or circuits under test to be repaired and desoldered from the entire circuit or printed board, and the robot circuit board is repaired and desoldered, which is more laborious to operate, but the results are accurate and reliable.

Use the resistance method to measure the robot circuit board to repair the integrated circuit, generally first connect a meter pen to the ground, use another meter pen to measure the resistance value of each pin to the ground, and then exchange the meter pen to measure again, and compare the measurement value with the normal value (some repair data are given, or stacked by yourself), and the larger difference is often the fault. (It doesn't have to be that the integrated circuit is bad!) )

The resistance method is very useful and convenient for determining the on-off of switches, connectors, wires, printed board conductive patterns and the transformation of resistors, capacitor short circuits, inductance coil breaks, etc., but for transistors, integrated circuits and circuit units, it is generally not possible to directly determine the faults, and the demand is compared with analysis or other methods, but because the resistance method does not need to energize the circuit, the detection danger can be reduced to Zui small, so the general detection is selected.
