Base Metal Co-Fired Multilayer Piezoelectrics
Piezoelectrics have been widely used in different kinds of applications, from the automobile industry to consumer electronics. The novel multilayer piezoelectrics, which are inspired by multilayer ceramic capacitors, not only minimize the size of the functional parts, but also maximize energy efficiency. Development of multilayer piezoelectric devices is at a significant crossroads on the way t...
متن کاملNovel ultra-low temperature co-fired microwave dielectric ceramic at 400 degrees and its chemical compatibility with base metal
A novel NaAgMoO4 material with spinel-like structure was synthesized by using the solid state reaction method and the ceramic sample was well densified at an extreme low sintering temperature about 400°C. Rietveld refinement of the crystal structure was performed using FULLPROF program and the cell parameters are a = b = c = 9.22039 Å with a space group F D -3 M (227). High performance microwav...
متن کاملPotassium Sodium Niobate-Based Lead-Free Piezoelectric Multilayer Ceramics Co-Fired with Nickel Electrodes
Although lead-free piezoelectric ceramics have been extensively studied, many problems must still be overcome before they are suitable for practical use. One of the main problems is fabricating a multilayer structure, and one solution attracting growing interest is the use of lead-free multilayer piezoelectric ceramics. The paper reviews work that has been done by the authors on lead-free alkal...
متن کاملFailure Analysis of Dielectric Breakdowns in Base-Metal Electrode Multilayer Ceramic Capacitors
Leakage current measurements of BaTiO3-based X7R multilayer ceramic capacitors (MLCCs) with base-metal electrodes (BMEs) have revealed three distinct failure modes: avalanche breakdown (ABD), thermal runaway (TRA), and slow degradation. Failure analysis (FA) was performed for a number of BME capacitors that failed with the aforementioned three failure modes. The samples that failed with ABD had...
متن کاملHighly Accelerated Life Stress Testing (HALST) of Base-Metal Electrode Multilayer Ceramic Capacitors
An improved highly accelerated life stress test (HALST) procedure and modeling method was developed to evaluate the reliability of multilayer ceramic capacitors with base-metal electrodes (BMEs). Reliabilities of ceramic capacitors with precious-metal electrodes (PMEs) and BMEs are discussed. A combination of leakage current and mean-time-to-failure (MTTF) measurements under accelerated life st...
