Patent ID: 8228083

Claim:
A testing system, suitable for testing a device under test (DUT), the DUT having a first signal pin and a second signal pin, the first signal pin being disposed on a lower surface of the DUT, the second signal pin being disposed on an upper surface of the DUT, the testing system comprising: a testing platform comprising: an electromagnetic shielding chamber having an opening; and a test-bench module disposed in the electromagnetic shielding chamber, the test-bench module having a first testing contact and a second testing contact; and a pick-and-place device movably disposed above the testing platform, the pick-and-place device comprising an electromagnetic shielding cap and a signal wiring structure, the pick-and-place device being used for placing the DUT on the test-bench module; wherein when the pick-and-place device places the DUT on the test-bench module, the first signal pin of the DUT is electrically connected to the first testing contact of the test-bench module, and the second signal pin of the DUT is electrically connected to the second testing contact of the test-bench module via the signal wiring structure; wherein the electromagnetic shielding cap corresponds to the opening of the electromagnetic shielding chamber, and when the pick-and-place device places the DUT on the test-bench module, the electromagnetic shielding cap cooperates with the electromagnetic shielding chamber of the testing platform to form an electromagnetic shielding space for isolating the DUT.
