Abstract: A test system for high voltage testing of semiconductor devices including at least one test socket and a docking plate assembly. Each test socket includes a socket enclosure for encompassing first and second contact finger assemblies, in which the socket enclosure may include a cover and alignment plate. At least one test socket is embedded within the docking plate assembly which is configured to mount between high voltage test head and a pick and place handler. The docking plate assembly and each test socket includes one or more site openings each for receiving a corresponding device under test (DUT) during a high voltage test procedure. Each contact finger assembly includes at least one contact finger configured as an elongated conductor with a bent tip for electrically interfacing a pad of the DUT.

Abstract: A test system for testing RF PCBs including an RF probe for interfacing an intermediate node of each RF PCB, an RF source providing an RF test signal, a reflectometer, and a test measurement system that makes a pass/fail determination of each RF PCB using a measured reflection coefficient. Each RF PCB includes an IC matching circuit and an antenna matching circuit coupled between an RFIC and an antenna, in which the intermediate RF node is between the matching circuits. The reflectometer outputs a measured reflection coefficient indicative of a comparison between a reflected RF signal and the RF test signal. The measured reflection coefficient may be corrected using error values based on a calibration procedure using a calibration kit with modified RF PCBs with known loads. The modified RF PCBs are measured with a network analyzer and the test system to calculate the error values used for production testing.
