When the components are broken, they can be detected by both the eye observation and the instrument. But sometimes when we solder components on a PCB board, we can't detect the problem, and the circuit board can't work properly. A lot of novices can't solve the problem, so it needs to make a new board, or it needs to buy a board. In fact, in many cases, the performance of components may be unstable.
In this situation, the instrument is not helpful, you can try to judge the fault by current and voltage to minimize the range. Some experienced engineers may be able to quickly determine the fault area, but it is not certain which component is broken. The only way is to replace the suspect component until the problem component is found. Last year, my laptop motherboard came under water, and when I was repairing the board, I also encountered a failure test, and replaced three parts during the repair process, namely, power supply chips, diodes, and USB charging components. Finally, it is through a wave of detection to replace the suspicious chip, the final determination is a component short-circuits.( online pcb fabrication)
