Foxconn uses Sensewee smart electric screwdrivers to perform stud detection.
2020-05-19

The 3C circuit boards produced on Foxconn’s assembly lines frequently encounter issues such as false soldering of studs, solder slag falling into the stud cavities, and stripped threads on the inner sides of the studs. If these defects were to be detected one by one manually using go/no-go gauges, the process would be inefficient and prone to errors. Therefore, Foxconn urgently needs automated equipment that can quickly, efficiently, and accurately inspect batches of studs on 3C circuit boards.
So, what tool can be used to implement this detection function?
Can a standard electric screwdriver with go/no-go gauges be used for inspection? The answer is no. A standard electric screwdriver equipped with go/no-go gauges cannot quantify standards using data, making it impossible to detect issues such as false soldering of studs, solder slag falling into the stud cavity, or stripped threads on the inner side of the stud.
The Sensewee smart electric screwdriver can establish criteria for detecting false soldering of studs, tin slag falling into the stud cavities, and stripped threads on the inner side of the studs, based on the number of turns and torque. According to the various possibilities outlined in these criteria, it can be programmed to automatically determine inspection results.
