The invention relates to a heating circuit for an
integrated circuit. The heating circuit comprises a fixing frame, an
integrated circuit and a heating board, wherein the
integrated circuit and the heating board are fixed inside the fixing frame; bolts are arranged on the integrated circuit and inside the heating board; the bolts are connected with the integrated circuit and the heating board through screw holes; an upper part of the integrated circuit is provided with a pressurized ball and a spring; a movable rod is arranged on upper parts of the pressurized ball and the spring; a lead, a fixing rod and a
copper sheet are arranged on the inner side of the fixing frame; one end of the fixing rod is fixedly connected with the inner side of the fixing frame by
welding, and the other end ismovably connected with a movable rod through a rotary shaft; and the
copper sheet is fixedly connected with the inner side of the fixing frame by embedding. Through adoption of the heating circuit ofthe integrated circuit, the pressurized ball is arranged in the fixing frame, and the
copper sheet is switched on / off under the control of the pressurized ball in order to control the on / off of the circuit of the heating board, so that the heating board is used for heating the integrated circuit under the control.
