This is the BEST way to IDENTIFY SMD components of any board. In this basic electronics video tutorial we are going to see how we can identify the SMD or surface mount components. Before starting the video, remember that the main capacitor must be discharged since it can remain charged with a fairly high voltage, the first component What we are going to analyze are the SMD ceramic capacitors responsible for many breakdowns, they work the same as a rectifier, for the second component we have the SMD resistors, you have to know the resistance codes to know their value, on my channel I have a video on how to know the value of a resistor. For the third component we have the SMD rectifier diodes, also responsible for many breakdowns, for the fourth component we have the transistors that can be of the NPN or PNP type, then we will look at the IGBT type or MOSFET type power transistors. The next component are the optocouplers, also in the channel there is a homemade tool to know if they are damaged, then we will see the SMD fuses here it is basically continuity with the digital multimeter, the next component is the chopper type transformers that I also have a tool in the channel homemade to know if the transformers are active, the next component are the coils or inductors, it is also continuity, the next component is the SMD electrolytic capacitors, if we do not have the same one, we can replace it with an electrolytic insertion one, the next component is the integrated circuits On the board they put IC, then we are going to see the ZENER diodes, we have to know what value they are and finally we are going to see the quartz or crystal oscillators and we are going to see what they are for.
