Measuring capacitance without desoldering capacitors from a PCB – is it possible?

At institution we were educated that if 2 capacitors are linked in parallel, their equal capacitance will certainly be equivalent to the amount of their private capacitance. Right here we have a PCB and also we desire to determine capacitance of this capacitor. When we attach a multimeter, or an additional gadget that determines capacitance, to those get in touches with, we will certainly get a worth of the real capacitance just if one solitary component, this capacitor, is firm in between those 2 factors. In the 2nd action I will certainly determine capacitance in those factors without desoldering the capacitors. In this video clip I have actually revealed you that gauging capacitance without desoldering capacitors from a PCB is a misconception.

Determining capacitance without desoldering capacitors from a PCB
Hey there. Our today’s video clip has to do with capacitance dimensions. Not simply routine capacitance dimensions yet dimensions without desoldering capacitors from a PCB.
Throughout the previous a number of years various web markets are supplying numerous gadgets that can determine capacitance and also various other criteria of capacitors without desoldering them from a PCB.
Of all, the producer details never ever consist of widely known brand names like FLUKE, APPA, UNI-T, MASTECH, and so on, are never ever existing in maker listings. At institution we were instructed that if 2 capacitors are attached in parallel, their equal capacitance will certainly be equivalent to the amount of their specific capacitance. We have to deal with upside down worths, so 1/C = 1/C1 + 1/C2.
Right here we have a PCB as well as we desire to determine capacitance of this capacitor. When we link a multimeter, or one more gadget that gauges capacitance, to those calls, we will certainly get a worth of the real capacitance just if one solitary aspect, this capacitor, is firm in between those 2 factors. Capacitance in between those 2 factors will certainly be equivalent to some equal worth, which is not that very easy to compute.
Out of inquisitiveness, we will certainly gauge capacitance in this factor. In the 2nd action I will certainly gauge capacitance in those factors without desoldering the capacitors. In the 3rd action I will certainly desolder all capacitors, gauge their capacitance in a typical means and also tape the worths.
