Patent ID: 7145283

Claim:
A piezoelectric device comprising: a piezoelectric vibrating reed having excitation electrodes, a package with outer terminals into which the piezoelectric vibrating reed is mounted; and a strip of insulating material having electrical conductors in the form of wiring patterns disposed thereon for forming an insulating bonding (“TAB”) tape, with said TAB tape being interposed in said package such that the excitation electrodes of said piezoelectric vibrating reed are interconnected to the outer terminals of the package through the conductive wiring patterns on said TAB tape, wherein said TAB tape includes a opening or a plurality of openings in the form of windows extending therethrough; wherein the wiring patterns are formed on a surface of insulating tape facing mounting electrodes; wherein the wiring patterns are formed on the surface of the insulating tape with portions of the wiring patterns overlying the windows; and wherein the piezoelectric vibrating reed is mounted on the TAB tape with the excitation electrodes connected to the wiring pattern via said windows.
