Description
Technical Field
[0001] The utility model belongs to the technical field of sensor gold wire bonding tooling, in particular to a gold wire bonding tooling for sensor pins. Background Art
[0002] The pins in the sensor need to use the gold wire bonding process to establish electrical interconnection between the internal circuit of the chip and the external package or substrate. Gold wire bonding plays a vital role in semiconductor packaging and microelectronics manufacturing. The sensor pins need to be clamped and fixed during the gold wire bonding process to prevent the pins from shifting during the gold wire bonding process, resulting in connection deviations, which will affect the actual performance of the sensor in the later stage. Excessive deviations may cause the pins to be directly scrapped, resulting in an increased scrap rate. Most common sensor pin gold wire bonding tooling can only clamp and fix pins of specific specifications. When the model and specifications of the sensor pins change, this tooling can no longer be used, and the work needs to be adjusted or replaced with a new one, which will cause a certain amount of waste.
[0003] Secondly, the adjustment or replacement of work requires a certain amount of manpower and material resources, which will also increase costs. In addition, the adjustment and replacement of work takes a certain amount of time, which will affect normal production tasks.
[0004] In summary, the gold wire bonding work of the sensor pins cannot adapt to the use of pins of different specifications, which will cause certain problems. Therefore, it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
