Integrated circuit block recovery method and system

The invention provides a method for recovering integrated circuit blocks and a system thereof. The method for recovering integrated circuit blocks includes the following steps: first, pressure vessel equipment, at least a tray and a pressure plate are provided and the interior of the pressure vessel equipment can be evenly heated and injected with compressed air and the number of the pressure plates is equal to that of the trays; second, integrated circuit blocks are dismantled from a panel board and a printed circuit board; third, the integrated circuit blocks are placed on the tray and covered with the pressure plate and then put in the pressure vessel equipment to be treated with hot pressing according to the predetermined temperature, time and pressure so as to improve the flatness of the integrated circuit blocks each of which is corresponding to one tray and one pressure plate; finally, the integrated circuit blocks are taken out of the pressure vessel equipment and stored to be put into production when
