One kind of a bonding wire camber test fixture and test method

The present invention discloses a bonding wire arc height test fixture, comprising a jig main body, an upper surface of the jig main body is provided with an inverted L-shaped groove, perpendicular to each other between the inverted L-shaped groove of the long and the short bevel bevel . The present invention also discloses a testing method using the jig. By bulb to be tested is placed on an angle of inclination of the jig, can be measured by the length of the bonding wire projection microscope, calculated from the corresponding formula camber, the method of measuring the bonding wire loop high precision ± 20μm, design to meet the requirements for the measurement circuit package bond wire, a good solution to microwave device package bond arc during high measurement problems, and simple structure, low cost, easy to use and maintain.
