Hot-pressing process, manufacturing method of BGA product and BGA product

The invention discloses a hot-pressing process, a manufacturing method of a BGA product and the BGA product. The hot-pressing process is suitable for brittle product processing. The applied hot-pressing equipment comprises a control system, a driving piece, an extrusion piece, a heating module and an electromagnetic induction piece, and a ferromagnetic piece is arranged on the brittle product; when the temperature of the heating module reaches a first preset temperature, the control system controls the driving piece to drive the extrusion piece to move towards the to-be-hot-pressed product; when the extrusion piece is in contact with the to-be-hot-pressed product, the control system controls the electromagnetic induction piece to be powered on to drive the extrusion piece to extrude the to-be-hot-pressed product; and when the temperature of the heating module reaches a second preset temperature and the moving distance of the extrusion piece reaches a preset threshold value, the control system controls the hea
