Susceptibility & EMI Scanners
     

Manufactured and Serviced in Santa Clara, CA

SmartScan™ Immunity (Susceptibility) and EMI Scanners

 

 BASIC,  AUTOSCAN,   AUTOSCAN EMI  &  PROFESSIONAL Models

Amber Precision Instruments of Santa Clara announces the world’s first fully automated immunity scanner for accurately pinpointing areas of system and device susceptibility to the effects of Electrostatic Discharge (ESD) and other electrical disturbances. By stimulating areas of a board or system and monitoring for system upset, SmartScanTM plots and displays sensitive areas including relative levels of sensitivity.

 

SmartScan is a diagnostic tool used at both the system and device level to rapidly identify potential susceptibility problems and provide the analysis required to develop a solution. Device manufacturers can for the first time, evaluate and qualify products resistance to upset and unwanted resets. Using a combination of E-field and H-field probes plus direct injection, sensitive areas are not only identified but quantified in terms of relative susceptibility.

 

Sophisticated software analysis provides a range of 3 dimensional color plots overlaying the actual device or board being tested. A complete range of options and potential upgrades are available for SmartScan that allow RF scanning, resonance scanning, multiple failure detections modules and of course, the ability to do full EMI scanning as well

 

Scanning can be used to compare devices from different manufactures to determine relative sensitivities.

PC Board remained the same, ICs are from two different manufacturers

 
     
 

In the design phase of a board, identify sensitivities due to poor circuit layouts

The sensitivity of this mother board would likely be improved by modifying the layout

 
     
 

A product that fails compliance testing can be quickly assessed and fixes put in place.

Eliminates the “Let’s try some ferrites and see if that helps” method of troubleshooting

Instead, the engineer knows exactly where to go and has some clues about what the appropriate fix might be

Options

Susceptibility scanners use a pulse generator specifically designed to produce a fast rising pulse simulating the E and H fields produced by an ESD (Electrostatic Discharge) event. The pulse is coupled via E and H field probes and either manually or automatically scanned over the surface of a suspect circuit. Once the susceptibility effect is localized, direct injection probes and software analysis can be used to identify specific IC pins or nodes that are the root cause of a susceptibility problem.

 

A susceptibility test that can be done by both the system manufacturer and the device manufacturer.

·         It’s a test that can be done by both the system and device manufacturer – and the results are meaningful to both.

·         As a preventive measure during design or device selection, it provides the engineer with a tool to see potential problems before a product is put into production.

·         For resolving EMC susceptibility problems in a sub-assembly or finished product, it provides a method to quickly see those areas likely to be the root cause of upset or malfunction.

·         For the device manufacturer it’s an invaluable tool for determining the sensitive of a device – something rarely done in industry today.

Susceptibility testing doesn’t replace system level testing to compliance standards or device level testing for voltage withstand during handling. What it will do is provide a tool that can be used by both the system level manufacturer and the semiconductor manufacturer to identify susceptibility problems at every level – device, board, sub-assembly and system.

In addition to identifying a sensitive component or circuit, testing must be able to quantify susceptibility levels and ideally correlate these results with the system level test results. Simply doing a system level test on a device is useless unless susceptibility levels can be determined and quantified.

System level ESD test

The methodology for system level ESD testing is standardized in the IEC 61000-4-2 standard.

This standard sets minimal requirements and gives information on the test setup. The standard setting body had hand testing in mind, but did not exclude robotic testing. As hand testing was in mind many minimal parameters have been set such that repeatability problems result.

Three main parameters are:

  •  Number of discharges

  • Approach speed, angle of approach

  •  Voltage increments
