பழுதுபார்க்கவும் தூண்டல் உருகலை உலை firstly eliminate the fault, and then debug

In the overhaul, the circuit fault should be eliminated first, and then the debugging should be carried out. Because debugging must be carried out under the premise of normal circuit. Of course, some faults are caused by improper debugging. At this time, you only need to debug directly to restore to normal. Be sure to pay attention to the welding quality when replacing the components, so as not to cause false welding. In addition, the welding time should not be too long, so as not to damage the components and cause unnecessary economic losses. Multiple soldering of electrical and electronic components can easily cause the copper foil to fall off the circuit board. After replacing the components, the foreign objects in the induction melting furnace should be cleaned up in time, the wiring and connectors should be checked again, and installed in place, so as to avoid other human failures.
