Abstract:
An apparatus for bonding wires and testing electrical characteristics of a solid actuator, comprising:(a) bonding means for bonding a first wire to a first pad and a second pad formed on a substrate of the solid actuator; (b) conduction testing means for testing conduction of the first wire connecting the first and second pads; (c) capacitance testing means for determining, after a conduction test effected by said conduction testing means in paragraph (b), whether or not a capacitance between the first and second pads and a ground pad has a preselected value; (d) said bonding means operative after conduction testing and capacitance testing in paragraphs (b) and (c) for bonding a second wire to a third pad and a fourth pad formed on said substrate of the solid actuator; (e) said conduction testing means operative for testing conduction of the second wire connecting the third and fourth pads; and (f) said capacitance testing means operative for determining, after a conduction test effected by said conduction testing means in paragraph (e) whether or not a capacitance between the third and fourth pads and said ground pad has a preselected value.
