This invention belongs to the field of integrated circuit equipment technology and discloses a high-damping vibration-damping base for integrated circuits, including a lower base. The integrated circuit equipment is placed inside the upper base and is centered and clamped by four first flexible square rings in the clamping assembly. When the integrated circuit equipment is used and subjected to vibration during operation, the upper base vibrates. The force on the upper base is transmitted to the second block, the second spherical rod, the elastic damper, the first spherical rod, and the first block, causing the elastic damper to extend and retract, thus mitigating the impact force generated during vibration. Since the multiple second spherical rods and the first spherical rods can move in a circular motion around the second block and the first block, when the integrated circuit equipment vibrates irregularly, the impact force generated in multiple directions of movement of the integrated circuit equipment can be mitigated, reducing the vibration frequency of the upper base relative to the lower base.
