The invention relates to a testing device for welding gold wire pulling force and gold ball shearing force, comprising a workbench, a gold ball shearing force testing device, a gold wire pulling force testing device and a microscope device. The working table includes a fixture platform, a rotating platform and two mutually perpendicular guide rails for the horizontal movement of the fixture platform. The golden ball shear force testing device includes a horizontal moving platform, a first support, a push knife support and an adjustment rod for adjusting the height of the push knife support, and a sensor and a shear force controller for testing shear force are arranged in the push knife support. The gold wire tension testing device includes a second bracket, a tension testing main body, a crochet hook adapter rod and a suspender for adjusting the height of the crochet hook transition stick, and a tension testing sensor and a tension controller are arranged in the tension testing main body. The invention can adapt to the measurement and observation of different detected objects through adjustment, and transmits the force signal to the peripheral computer equipment through the sensor, so that the curve diagram of the force changing with time in the whole process can be observed conveniently.
Description
technical field [0001] The invention relates to a mechanical measuring instrument, in particular to a testing device for measuring the pulling force of welding gold wire and the shearing force of gold balls. Background technique [0002] The integration of circuits and semiconductor devices promotes the continuous improvement of packaging. Although the general trend is to integrate on silicon chips, the number of circuits that can be fabricated on a silicon chip has certain limitations in actual development, so it is still It is necessary to interconnect the chip to an organic or ceramic first-level package, and the electrical connection between the chip and the package is called chip-level interconnection. Wire bonding is a type of chip-level interconnection and the earliest interconnection method used in semiconductor devices. Over the years, it has been struggling to overcome the shortcomings in reliability, manufacturability and cost. Therefore, in the semiconductor ind...
