ABSTRACT:
A decoupling capacitor system for improving the reliability of digital logic circuit boards such as single inline memory modules which use surface-mount decoupling capacitors. The system comprises one or more units of two or more series-connected capacitors connected between the chip supply voltage (Vcc) input and the chip ground (Vss) connection. Given no change in the reliability of the individual capacitors, the reliability of a circuit board can typically be improved by several order of magnitude.
