  • Patent number: 10203369
    Abstract: A test interface board includes an encoder, a signal copier, and a decoder. The encoder digitally encodes test data to generate a modulation signal. The signal copier copies the modulation signal by inductively coupling the modulation signal and outputs at least one copy signal corresponding to the modulation signal. The decoder decodes the modulation signal and the at least one copy signal in order to test at least two semiconductor devices.

  • Patent number: 7816937
    Abstract: An apparatus for testing an object includes a test chamber, a guiding member, testing units and a transferring unit. The test chamber is configured to receive the object. The guiding member is arranged extending along a first direction in the test chamber. The testing units are movably connected to the guiding member to test electrical characteristics of the object. The transferring unit is arranged in the test chamber to load the object into one of the testing units and unload the object from one of the testing units. The testing units may be transferred to a position for repair without suspension of the apparatus. The object may be tested using another testing unit while the other testing unit is being repaired.
