Conductive layer 900 may comprise sharp corner 902 present in the standard end, which may produce structural instability and unwanted ‘hot spots’ that can lower maximum operating voltage. The lamination strength may be increased through a process of ‘quilting’, which is made possible with the systems and methods of the present invention, namely the technique of drop-on-demand printing, as the prior art process of ‘tape casting’ would not be able to accomplish this technique. Ceramic capacitors may be created by tape casting, in which a slurry of powdered ceramic and binder is spread over a flat surface with a knife edge to create the insulator, and coated with conductive ink. Cross-sectioning examinations revealed also a crack that connected opposite electrodes and appeared to emanate from the end of delamination.

The aforementioned materials can be sintered at high temperatures, and therefore are amenable to integrated manufacture. 62/279,649, ‘Methods and systems to minimize delamination of multi-layer ceramic capacitors’, filed Jan. 15, 2016. Particularly in the case of a physically large MLCC, there is possibility of delamination under the stress of temperature and/or pressure. The choice of pattern may depend on a predetermined mechanical strength value of the quilting and/or the maximum voltage rating of the MLCC. This is an inherently more precise and repeatable process than traditional methods, and produces higher density components with less material waste. simple in design, but multilayer ceramic capacitors (mlccs) are nevertheless capable of causing un-anticipated field failures whose severity may range from very minor to catastrophic. The residual stress in a multilayer ceramic capacitor (MLCC) has been evaluated by two‐dimensional finite element simulation in combination with X‐ray diffraction measurement. Operation 1510 deposits a first conductive layer onto a surface. Operation 1630 dries any liquid from the powder bed, e.g., infrared flash-dry, after deposition of each layer.

Operation 1450 dries the powder bed by flash drying, e.g., infrared heating. Therefore, the choice of shape depends on whether the capacitor performance is limited by maximum voltage or maximum strength. Sintering is a solid-state diffusion process that may be enhanced by increasing the surface area to volume ratio of the powder in any green part that is subsequently sintered. The rounded configuration may give the benefits of increasing maximum voltage through the reduction of areas of intense electric field, and may increase structural strength through the removal of stress singularities. The exact design will be a function of the product requirements determined by marketing, so a highly delamination-resistant MLCC may have more quilting for high-temperature or high-pressure environments, for instance.

The MLCCs were electrically tested. Other configurations may also be possible, such as bulbous or wavy shapes. The tradeoff may be that a more complex cross-sectional shape for the pillar connections may create regions of high electrostatic intensity that may limit the voltage to which the device can be charged, although maximum strength and resistance to delamination may be increased. Operation 740 repeats operations 720 and 730 until a green part is formed. Thus such design are ideal for RF and microwave filter designs.
