You can check the capacitor without unsoldering it from the chip. To do this, you need to connect a capacitor with the same capacity in parallel. If the device will work, the problem is in the first element, and it should be changed. This method can only be used in low voltage circuits! Sometimes they check the capacitor for sparks. - Download [PDF]

Capacitor Construction. A capacitor is constructed out of two metal plates, separated by an insulating material called dielectric. The plates are conductive and they are usually made of aluminum, tantalum or other metals, while the dielectric can be made out of any kind of insulating material such as paper, glass, ceramic or anything that obstructs the flow of the current.
Since they do not depend on relatively high-resistance electrolyte solutions for their operation as do electrolytic devices, the ESR of ceramic capacitors tends to be quite low, and their internal geometries (and short lead lengths, in the case of MLCCs) render board layout the dominant contributor to ESL in many cases.
