It should open the PCB diagram on the computer, light up the short-circuit network, and see where the nearest place is most easily connected. Special attention should be paid to the IC internal short circuit.
If there is a BGA chip, because all solder joints are not visible by the chip. It is multilayer (above 4 layers), so it's best to separate the power supply for each chip at design time. And it connects with a magnetic bead. In this way, when the power and ground short circuit occurs, the magnetic bead detection is disconnected, and it is easy to locate a chip. Because of the difficulty of BGA welding, if not soldering by machine, a little less attention will cause short circuits to the power and solder points.
We must be careful when small size surface mount capacitors are welded. Especially the power filter capacitors can easily cause short circuit between the power supply and the ground. Of course, sometimes the capacitor is short-circuited, so led circuit board makers think that the best way is to check the capacitance before welding.（custom pcb printing）
