troubleshooting tips
The most common troubleshooting techniques are listed below:
a) power check (capacitor,diode,voltage regulator,power line)
b)Visual inspection- to detect the posible faults(cold solder and any burnt component)
c)using sense of touch- overheated component
d)smell check-fail due to overheating that cause the component become burnt
e)component replacing
f)Signal tracing(using multimeter,DMM,oscilloscope)
Steps to better soldering:
The ability to solder is an essential skills for anyone involved with electronics. A single bad joint can take hours of fault-finding to isolate, and considerably raise the stress ladders of the constructor.
The soldering process enables teo metal surfaces to be joined by addition of molten filler which "sets" to form a solid connectio. In electronics work the filler is an alloy of 60% Tin and 40% Lead. This alloy is supplied in the form of a wire with cores of flux running through it. The flux is a very aggresive chemical, activated by the heat of the soldering iron. Its job is to strip away all of the grease from the surfaces to be soldered, thus ensuring that the solder will flow properly.
Choosing the Right Equipment:
Soldering Iron
Factors to Consider
-Wattage
-Tip temperature
-Tip profile
