Many companies have experienced failure of multi- layer ceramic capacitors due to printed wiring board bending and have placed controls in their manufacturing process to limit the amount of bending (or flexure) of the PWB to eliminate these failures.
One of the most common causes of capacitor failures is directly attributable to the bending of the printed circuit board (PCB) after solder attachment. Excessive bending will create mechanical stress within the ceramic capacitor that, if sufficient, can result in mechanical cracks.
For International Specifications and Knowles Precision Devices Bend Test Methods refer to the Bend Testing section. Reduce the mechanical stress being exerted on the capacitors. And/or increasing the process window so that the mechanical stress exerted onto the ceramic section of the capacitor is reduced.
