Abstract:

A conductor trace array includes an electrically insulative support substrate and a plurality of pairs of electrical signal conductor traces and a plurality of pairs of passive electrical conductor traces. All of the traces are formed along substantially parallel paths in a single layer on the substrate. Each pair of the electrical signal conductor traces is arranged on the support substrate such that they are positioned in a space defined between each pair of passive electrical conductor traces. As a result, each pair of signal conductor traces has a passive electrical conductor trace positioned immediately adjacent thereto. The passive conductor traces generally follow a geometry of the signal conductor traces and thereby form a capacitive coupling relationship therebetween. This capacitive coupling relationship increases the characteristic impedance of the signal conductor traces. A preferred application is for interconnecting a head and a preamplifier/drive circuit within a hard disk drive, wherein the interconnecting trace is expressly provided upon an E-block of the activator.
