ABSTRACT:
The present invention describes an intermediate for use in a capacitive printed circuit board (PCB), which relates to a capacitive apparatus and manufacturing method for a built-in capacitor with a non-symmetrical electrode used to reduce inaccuracy of the error compression alignment on laminates. The invention employs a plurality of different sized metal laminates stacked for a built-in capacitor to achieve a high-precise capacitor PCB. More particularly, the invention can raise the capability of noise-immunity of a capacitive PCB applied to high frequency/speed modules and systems, and also provides precise capacitance to regular circuit design for the need of compact package and high-precise capacitance in the future.
