Ceramics used in electronics are everywhere. For instance, ferroelectrics are used to create high-dielectric capacitors and non-volatile memory devices. Ferrites play a crucial role in storing data and information. Solid electrolytes are instrumental in the storage and conversion of energy. Piezoelectrics are essential for sonar technology, while semiconducting oxides have been pivotal in monitoring environmental...

With the growth of the semiconductor industry, the density of circuits within integrated circuits (ICs) has increased. Even with the increase in density, the number of input-output pins remains unchanged, which is one of the reasons for the increased complexity in IC packages. To ensure the reliability of ICs, IC testing is introduced at every stage of the production...

PCBs for commercial products must pass a set of reliability tests in order to prove their capabilities, which goes well beyond the standard functional testing found in many products. Functional tests are the starting point, but reliability tests are where a design is proven for operation in its intended environment. To help designers plan a...
