Another motherboard fault, but this one has been worked on before. Join me as I try to work out what is going on! Please like and subscribe and leave any comments below.
When you are soldering or desoldering a two-terminal SMD component, such as a capacitor, is it better to grab it by the sides with your tweezer, rather than by the metal terminals? If your tweezer tips are touching the metal terminals, the tweezer acts as a heat sink, which makes it take longer to heat the solder junction. Or perhaps it doesn't make a significant difference.
Thanks a lot ! super nice work, I would really like to know why the red probe on ground instead of black for the short circuit test in diode mode? THANKS
@transformateur: Hi. The internal battery of the multimeter, when using the Diode Test function, injects a voltage through the UUT (Unit Under Test), that is, in the case of a diode, to polarize it or make it enter its conduction state. If the Diode Test function is used as an "ohmeter" (Resistance Measurement) then the red (+) terminal of the meter must be brought to GND and that way the internal battery of the meter does NOT supply voltage to the UUT when it is touched with the negative (-) terminal of the DMM* or VOM**. *DMM = abbreviation Digital Multi Meter. VOM = abbrev. Volt Ohm Meter, for the analog meter, which uses a needle or pointer as an indicator on the graduated dial. All the best.
Hi @bionictran when I went to look for the datasheet for that particular IC, it was very confusing and unclear as to the functions of the pins, and I didn't want to make a video that would have had any value to the viewer. But I did learn the important lesson of not promising things I can't deliver !
Hi, I use an Epson V600 (CCD) to scan and then do some work in photoshop to bring out the text and colour. But just be aware that if you try to scan taller boards, it loses focus as you put more distance between the component and the scanner glass.
