Q: Where can I download the latest version of Huntron Workstation®?
A: The latest version of Huntron Workstation can be provided. Please contact us. Older versions (versions previous to 4.X) can still be provided. Please contact us.
Q: What are the differences between Huntron Workstation 4.2 and 4.3?
A: Huntron Workstation 4.3 uses a different database format that requires 4.2 tests to be converted before they can be used in 4.3. Here is a more complete list of the major enhancements:
- New Database format with increased read speeds and no limit on file size
- Supports conversion of all 3.X and 4.x databases including HBK files (verson 2 and 3 backup files)
- Tracker Model 3200S Support
- Access RF Prober support
- Access DH 50 mil and 39 mil probe-to-probe spacing enabled
- Image based work directions can be embedded into Board, Sequence and Components level Instructions
- Enable/Disable testing of individual Components
- Support for Windows 8 and Windows 10; No longer tested in Windows XP
- Built-in Utility for updating Tracker Model 30, Tracker 2800/2800S and Tracker 3200S firmware
- Component Level Group Edit that allows for copying Component settings to other selected Components including Access DH Z1 and Z2 positions
- Pin Offset feature for moving robotic probe positions away from component bodies
- Support for new ProntoVIEW Markup CAD data import software from Unisoft; CAMCAD Professional not supported
- Improved CAD Import process with additional controls to customize the import
Q: I am new to Huntron Workstation®. Where do I start?
A: The best way to get started is by viewing the software tutorials included with the software package. Version 4 software includes Software and CAD Import tutorials with the installation.
It works best to print these tutorials for easy reference. For additional assistance, contact Huntron Technical Support.
Q: How do you store multiple signature sets for a component?
A: Huntron Workstation 4 allows for any signature scan to be set as a “Reference” and used for comparison. This could be used to store References from several known good PCBs. This can be extremely useful when dealing the differences in signatures from different IC manufacturers. Simply click the Set Reference button in the Signatures/Troublesheet tab after scanning or select the Reference check box in the Tree/Component (or Net) Scans tab. Although it is a legacy feature carried over from older Workstation versions, Version 4 also has the ability to create a Merge signature set by clicking the Merge button in the Signatures/Troublesheet tab after scanning. The Merge function creates a listing in the Component (or Net) Scans tab called Min/Max in addition to any scans set as a Reference. To control which signatures are used for comparison, set the Compare Priority setting by selecting Tree pane/Sequence tab and scroll right to the Compare Priority column.
Q: What can be done to a board test to shorten the test time?
A: The most beneficial method is to reduce the number of test points by creating a “net” test or testing only the unique nodes on the circuit. This eliminates any redundant re-testing of component pins. Generally, CAD data or schematics are necessary to create a net test.
Other things that can be done to reduce test time is to decrease the number of test ranges used (though we recommend using at least two), disabling the “Z Home between Components” in the Sequence settings and grouping small discrete components into one component test. Increasing the test range frequency to 200Hz or higher will also result in shorter test times. More suggestions such as probe position optimization are available in the Quick Tips Section of the Manual.
Q: What is Tolerance and how is it calculated?
A: The Workstation software allows the user to set a tolerance used when comparing stored good versus bad signatures. It is set on scale from 0 to 99 with 99 allowing the greatest difference between signatures. Tolerance as it relates to the Huntron software can sometimes be difficult to explain but here is our best short explanation. The software samples a single cycle of the applied sinewave regardless of frequency. For signature creation, sine information for both the voltage (horizontal) and current (vertical) are examined but only the horizontal data is used when comparing. We digitize these waveforms by plotting 100 locations across the entire waveform cycle. These points are the byte location. We then look at the location of where the waveform crosses through a particular byte location and assign it a number (referred to as a signature point). This signature point will be positive or negative depending on it's location within the byte location and can be 0-99*. The tolerance is the number allowed for a compared signature point to be "different". For example, your tolerance is set to 5. If the STORED signature point in byte location 10 is "20" and a compared signature point for the same byte location is "30", then the signature would fail because the difference between stored and compared is 10. If the compared signature point was 25, then it would pass. When viewing signatures in the Zoom mode or in the Troublesheet, the deviation (the Dev number) is how different the compared signature point is from the stored signature point minus the tolerance for the largest difference on that waveform. So essentially, the Dev number is the amount you would need to add to the tolerance to get a PASS result. The Area number is the sum of all deviant signature points and is used for sorting the failed signatures. In the Signature window, right-click the signature box and select Data from the menu to see the actual byte and signature (data) point information. This may help visualize how we derive the signatures. Voltage amplitude could be related to the signature but this would relate only to the horizontal signature information. For a Tracker range amplitude of 1Vpk, each signature point would be 1/100th of a volt making a signature point worth approximately .01V. This would mean that a tolerance of 5 would allow the horizontal voltage amplitude to differ by up to .05V. With this analogy, you can see why the tolerance is sometimes related to a percentage.
Special Note:Data byte values can exceed 99, but normal full scale is 100. Values like 101 or 102 (mostly on capacitors) could be displayed and it is possible for values up to 127 but this means that the voltage has exceeded the voltage output by the Tracker.
