However, the rotation precision of the motor 131 of the pressing device 13 cannot be finely adjusted, if the electronic device to be tested is a logic IC, the surface thereof can still bear the large downward pressure applied by the pressing device 135 by the motor 131, but if the electronic device to be tested is an RF IC, the surface thereof cannot bear heavy pressure, and when the motor 131 drives the pressing device 135 to press the RF IC with large downward pressure, the surface of the RF IC is easily damaged and broken, thereby affecting the testing quality.
