Abstract:
1. A method of fabricating a surface mounted crystal oscillator with pedestal, based on a determination of the quality of said pedestal, wherein said pedestal is to be provided on a base surface of a crystal oscillator from which a pair of lead wires extends, the method comprising the steps of: forming, in a mold, said pedestal by injection molding with a liquid-crystal polymer material, the forming step including forming one or more protrusions following the shape of said mold, said one or more protrusions extending upwardly from at least one corner of a periphery of an upper surface of said pedestal; determining a polymer chain quality of said pedestal from the molded state of said one or more protrusions, wherein the polymer chain quality of said pedestal is determined to be non-defective if an upper surface of each of said one or more protrusions is a substantially flat surface and is substantially parallel to the upper surface of said pedestal as an indication of straight chains of said liquid-crystal polymer being continuous, and the polymer chain quality of said pedestal is determined to be defective if the upper surface of said one or more protrusions is substantially ridged as an indication of straight chains of said liquid-crystal polymer being discontinuous after said injection molding; and mounting said pedestal, determined to be non-defective in the determining step, onto said base surface of said crystal oscillator, wherein the determining step is performed after the forming step and before the mounting step.
