Comprising a small pc-board with decoupling capacitors on one side and solder balls on the other, the QStack power delivery module attaches directly underneath a BGA package to reduce or eliminate the ...

Placing decoupling capacitors as close as possible to the BGA pads while routing is being performed is another important design technique, Fig. 3 . This is an effective way to reduce the noise at ...

Everyone knows that the perfect capacitor to decouple the power rails around ICs is a 100 nF ceramic capacitor or equivalent, yet where does this ‘fact’ come from and is it even correct? These are the ...

Editor's note: This article addresses the need for designers of printed circuit boards for nextgen ICs to be savvy about package-on-package technology. New ways of working with sub-assembly printed ...

Noise management, induced by digital circuits on a p. c. board assembly, deserves the attention of power supply designers and those mastering digital, analog, and mixed-mode application problems ...
