Abstract: A device for pressing an electronic component with different downward forces includes a first downward-pressure generating device, a depressing head, a second downward-pressure generating device and a depressing piston. The first downward-pressure generating device has the depressing head to apply a first downward pressure to the test socket and a portion of the electronic component. The second downward-pressure generating device has the depressing piston to apply a second downward pressure downward to another portion on the electronic component, so that the electronic component can couple electrically with a plurality of probe of the test socket. Thereupon, at least two downward-pressure generating devices are included to provide at least two different downward pressures to the electronic component solely or simultaneously to the electronic component and the testing equipment, such that specific downward-pressure requirements by precision electronic components can be fulfilled.

Abstract: An apparatus for testing a package-on-package semiconductor device comprises a pick and place device for loading a first chip into or unloading the first chip from a test socket and a lifting and rotating arm for moving a chip placement module which receives a second chip to a position between the pick and place device and the test socket. The pick and place device and the chip placement module are lowered, and then a test process is performed. After the test process is completed, the pick and place device and the chip placement module are lifted, and the lifting and rotating arm moves the chip placement module to one side of the pick and place device. Accordingly, a method for testing the semiconductor device could be performed automatically so as to greatly enhance test efficiency and accuracy and to significantly reduce costs.
