  • Page 36: On-Board Dut Sockets

    ASEK Hardware | On-Board DUT Sockets On-Board DUT Sockets The ASEK DUT interface PCBs provide three mounting areas for pre-designed DUT sockets. Use of pre-designed sockets allows the operator to perform DUT demonstrations on common pack- ages, without external wiring to DUTs. The three mounting areas are distinguished by the unique patterns of the through holes used to mount the sockets.

  • Page 37: Off-Board Dut Socket Connections

    ASEK Hardware | Off-Board DUT Socket Connections Off-Board DUT Socket Connections The ASEK interface PCBs can be used to connect user-designed DUT sockets or test fixtures that are not mounted on the interface PCB itself.
