Normal MLCC capacitors are vulnerable against tensions due to assembly process and after that especially during lead free process that is much hotter. soft termination caps are really more reliable but they are not the first choice for mass production even in safety critical applications.
soft termination caps are really more reliable but they are not the first choice for mass production even in safety critical applications. In mass production the solution is using two serial normal MLCC capacitors those are assembled perpendicular to each other in the PCB.
Flex cracks that occur in multilayer ceramic chip capacitors (MLCCs) Whereas excessive stress has caused cracking on the ceramic element of a conventional product, no cracking develops on the element with soft termination, even with peeling of the nickel plating layer and conductive resin layer.
Soft termination is a type of beads in which a conductive resin layer is provided between the Ag and Ni plating layer. (Fig. 2) Fig. 2: Difference between a regular terminal product and soft termination in inductors (coils) and chip beads; source: TDK Flex cracking is due to excessive circuit board flexure.
Soft termination is a type of MLCC in which a conductive resin layer is provided between the Cu and Ni plating layer. (Fig. 2) ・The resin layer absorbs stress accompanying expansion or shrinkage of a solder joint due to thermal shock or flex stress on the board and prevents cracking of the capacitor element.
It is for this reason that soft connections carry so much risk, in that they can be a source of stray current in a well, which can in turn trigger latch-up conditions. Of course, a “simple” fix in layout, would be to short the well connections together in metal, likely satisfying LVS/ERC checks and eliminating this risk.
A simple fix to this would be to short the well connection of device D, to the supply through metal, removing the soft connect and eliminating the ERC error. However, …
