Description

Technical Field

[0001] The invention relates to the technical field of DIP packaged chips, in particular to a DIP packaged chip pin shaping fixture. Background Art

[0002] Sometimes ordinary pliers or simple clamps are used to adjust the shape of the pins, but this method cannot accurately control the shaping angle of the pins, which can easily cause further damage or deviation of the pins. If the pins are not in the specified position, it may cause welding difficulties or produce cold solder joints, affecting electrical performance. Early pin shaping usually relied on operators to manually adjust the pins. Although this method is simple to operate, there are some problems, including low shaping accuracy, low efficiency, and easy damage to the chip. At the same time, manual shaping makes it difficult to ensure that the angle and spacing of each pin are consistent, which makes subsequent installation difficult.
