[0002] DIP packaged chip refers to an integrated circuit chip that uses a dual in-line package. Most small and medium-scale integrated circuits ICs use this packaging form. Chips using DIP packaging usually have two rows of pins, which are directly inserted into a chip socket with a DIP structure, or directly inserted into a circuit board with the same number of solder holes and geometric arrangement for soldering. After the package is completed, it is inevitable that the pins will have different degrees of flatness, and the uneven pins need to be restored to their original state.
