Test devices plug into DUT boards that are plugged into power and monitoring circuits inside a chamber that can hold up to 16 different device test boards with a maximum of 80 devices per board.
Each test board has a Test Complete LED that is turned on when the devices on that board have completed the test cycle.
Because each board is individually tracked, test boards can be inserted or removed from the test chamber without negating the test cycle on the other boards.
Custom DUT boards or a general purpose DUT board with custom inserts configure the package type or pinouts, allowing the ITC5230 to handle a wide variety of device types and packages.
All B model DUT boards can be used in the C model, but new measurement and test features may not be operational with the older boards.
ITC5230C Device testing is controlled and monitored by a PC/AT compatible computer. This computer provides greater hardware and software flexibility and allows for future hardware and software enhancements.
On Model C DUT boards, the Controller measures each device's ON current and junction voltage and converts the measurements to die temperatures using customer supplied conversion constants. (Not available on the generic DUT board.)
Additionally, ON current, ON time, device polarity, and test voltage are computer programmable (per board), allowing each board to test different device types and different packages. For Model B DUT boards, On time must be the same for all boards and test voltage is switch selected on each board.
For operator safety, all VDD power to all test boards is removed and the chamber blower is turned off when the test chamber door is opened on the ITC5230C. Also, device testing is interrupted but automatically restarted with a cooling cycle when the chamber door is closed.
