ABSTRACT:
An electrical test device including a substrate and a plurality of test pads. The test pads are disposed on a second surface of the substrate. Each test pad has a test hole, and first and second isolation slots. The first isolation slot is disposed on the periphery of the test hole, and defines a signal region for connecting a signal terminal of a test probe. The second isolation slot is disposed on the periphery of the first isolation slot, and a ground region is defined between the first and second isolation slots. The ground region is used for connecting a ground terminal of the test probe. The test pad can match with the test probe so that the test probe can connect to the test pad for providing signal to the test probe. The electrical test device can easily measure the real electrical characteristic of the signal from the substrate.
