6 FAQs about [Capacitor laboratory inspection]

Does a capacitor need a destructive test?

However, given the capacitor construction some non-destructive tests are not applicable. Destructive testing usually requires a cross-section and inspection; in some cases de-encapsulation or de-lid is performed to inspect internal surfaces. For leaded devices, it is likely that terminal strength testing or lead pull testing is to be performed.

What is a non-destructive test for a capacitor?

What is a capacitor used for?

A capacitor is a passive device used for storing electrical energy. In its most rudimentary form, a capacitor consists of two or more parallel plates (typically metal) separated by an insulating material. The insulating material is referred to as the dielectric; whereas the plates are considered electrodes.

What is the difference between a base metal electrode and a capacitor?

Whereas, base metal electrodes are usually comprised of less expensive metals like Nickel (Ni) or Copper (Cu). Typical non-destructive tests for capacitors include external visual examination, X-radiography, hermeticity testing and prohibited material inspection.

What types of capacitors are covered by MIL-std-1580?

Several capacitor types are covered within Mil-Std-1580 revision C, Requirement 10. Ceramic monolithic capacitors are also covered within ANSI EIA-469-E. Typically, the destructive physical analysis phase of testing includes cross sectioning to properly inspect passive internal components. DPA Testing for PMS.
