Flexibility_Multilayer_Capacitors 03/12/19 2 1.1 Introduction Due to its brittle nature of Ceramic, multilayer ceramic capacitors are more prone to excesses of mechanical stress than other components used in surface mounting. One of the most common causes of capacitor failures is directly attributable to bending of the printed circuit
Given the rapid improvements in the miniaturization, functionality, and efficiency of electronic products in recent years, the dielectric layers and electrodes of multilayer ceramic capacitors have become thinner, with the number of stacked layers also increasing.
Capacitors consist of two or more conductive plates (also called internal electrodes) separated by a dielectric material. As clearly denoted by the term ‘multilayer ceramic capacitor’ the dielectric material for MLCCs is a ceramic. The structure is shown in Figure 5.
As a result, the deformation defects induced during manufacturing of the capacitors have increased. In this study, the deformation behavior of a mul-tilayer ceramic capacitor composed of ceramic dielectric layers and Ni electrode layers during the compression process was analyzed numerically using the FEM.
As voltage variation is dependent on inductance, low ESL capacitor types are increasingly replacing conventional ceramic capacitors. The main advantage is reducing the overall occupied space and cost of the decoupling solution by requiring fewer capacitors for similar PDN performance obtained with standard MLCCs.
In this study, the deformation behavior in the plane direc-tion of MLCCs consisting of layers of a ceramic dielectric based on BaTiO3 and Ni electrode layers with voids during the pressing process was numerically analyzed using the FEM.
The inductance of any device is determined by its length to width ratio, known as the aspect ratio. As MLCCs are long and narrow, the natural evolution was to make them short and wide, thus reverse geometry capacitors were designed, which provide up to 50% lower inductance for a few fractions increase in cost over traditional MLCC.
