causes of capacitor failures is directly attributable to bending of the printed circuit board (PCB) after solder attachment. Excessive bending will create mechanical crack(s) within the ceramic capacitor, see Figure 1. Mechanical cracks, depending upon severity, may not cause capacitor failure during the final assembly test. Over time
