  • Patent number: 4941700
    Abstract: The present invention relates to a puller for pulling out Gate Array ICs having an axial rod centered into a cylindrical pipe. There is a buffer spring inside the cylindrical pipe and a round pressing board is attached to the bottom of the cylindrical pipe. A steel hook is fixed to the center of the axial rod with both ends bent in at 90.degree.. An arch spring is fixed to the axial rod right above the steel hook and extends downward. The two 90.degree. ends of the steel hook penetrate two holes at the ends of the arch spring. In using this invention, one may hold and press both sides of the arch spring, plug the two 90.degree. ends of the steel hooks into the diagonal holes of a chip carrier and pull the chip. The buffer spring pushes upward against the axial rod to reform the arch spring and the steel hooks so as to pull out the Gate Array IC.
