SmartScan-350/550 ESD is specifically designed for susceptibility scanning system.

A broad band pulse from a pulse source (TLP) is delivered to an electric field or a magnetic field probe. The generated field couples with components or traces of DUT or PCB, and causes failure. Or the pulse can be directly injected through direct injection probes. It mainly reproduces IEC 61000-4-2 test failure types, both soft and hard failures.

The probe is positioned at desired test points by a robot with software control, triggers the coupling and the response of the DUT is recorded for relative immunity level comparison. A simplified immunity set-up diagram and a sample immunity level plot (susceptibility map) are shown below.


Applications of the immunity scanning are
  Identification of sensitive spots, areas or traces to IEC 61000-4-2 type tests
  Estimation of system level ESD test performance at early stage of development
  Relative immunity level comparison before and after design change
  Selection of more ESD resistant parts (supplier-A over –B)


Hardware Configurations:

                Notes: (1) Contact API for other sizes of robots
                            (2) Contact API for other probes

ESD Box

   ESD Box consists of TLP and failure detection unit


Failure detection unit
  Four analog signal inputs
  Four digital signal inputs
  Three auxiliary inputs
  120V and DC power supplies for remote controlled DUT power cycle
  Optical sensors for image change detection
  Micro phone for sound On/Off detection
  Integration of DUT controllers
  Simultaneous monitoring of multiple signals
  Boolean operation of monitoring signals to control DUT reset and sort out failure types


TLP (Transmission Line Pulsar)
  200V to 8,000V transmission line charging voltage
  <300 pSec rise time and >6 nSec falling time to prevent causing failures at both edges


Software
  ESD test condition control and data visualization
  User friendly, intuitive and very flexible to integrate other scan technologies

Scan area editor (SAE)
  By a DUT location camera- The scan area is edited directly on the DUT picture taken by the camera. The software controls the movement of the probe to the defined scan points
  Flexible scan area selection - any shape and multiple scan area can be defined for optimum scan time. Height of each defined scan area can be given separate
  For large DUT's, multiple pictures are taken and they are stitched together to capture whole DUT image in one picture
