Huntron Automates Short Circuit Location

B+K Precision milliohmmeter

Huntron Technical Support ran some experiments to locate short circuits on printed circuit boards (PCB) recently. The process included a B&K Precision 2841 Milliohm meter connected to a Huntron Access DH2 dual head Prober. The Access DH2 automated the placing of the test probes on PCB components. We created Huntron Workstation test Sequences to control the Prober movement and capture measurements from the milliohmmeter.
We built two tests, the first on a bare board with no components. The second test used a fully populated circuit card with surface mounted components.

The Power of Huntron Workstation – Capture, Store and Compare Electronic Measurements

Workstation for Windows
Huntron Workstation for Windows, circa 1995. Microsoft Windows was still new to some users so we felt the need to point out all of the parts of a “Window”.

The Huntron Workstation software has had a long life in various forms since its introduction in the mid 1990’s. Along the way it has matured and grown into more than simply a way to control a Huntron Tracker with a PC. Let’s take a look at how Huntron Workstation started, where it is now and also look a bit into its future.

Capture, Store and Compare

We have come a long way… The multi-pane, flexible layout of Huntron Workstation version 4.3

In the beginning, the primary goal of Huntron Workstation was to control a Huntron Tracker so you could capture the analog signatures (V/I waveforms) of electronic circuits and store them on a computer. Having the signatures stored on a PC allowed you to use them later for comparison. This allowed you to compare the signatures of good circuit boards to those of bad circuit boards hoping that the differences would lead you to the problem. Your classic good vs. bad troubleshooting method.
As a side benefit to this capture/store capability was having the information organized in a database that provided a repeatable test process. A test for a circuit board would be created and used the same way by all of the technicians and engineers who accessed it. This essentially provided a way to “share the knowledge” rather than having to remember it in your head or write it down in some logbook. Capturing and storing test data is the first level in test automation that makes our job a lot easier than having to document information by hand.
The first versions of Huntron Workstation were created for Microsoft Windows 3.1 and as operating systems, PC specs and the electronics industry changed, Huntron Workstation did as well.

— March, 2017 — Huntron Inc. has announced the addition of the Huntron Access RF probing station to its product line up. “The Access RF prober applies precise mechanical automation to proven manual RF measurement practices” said Brad Grams, President of Huntron Inc. “Using Near Field measurement techniques we are able to robotically place the Antenna (probe) in the exact position and consistently measure expected values. This method provides more accurate information free from plus/minus swings in deviation experienced when using manual probing.”

Ensuring test flexibility and Accuracy

The Huntron Access RF provides reliable and repeatable Near Field measurements of RF signals. By combining a Huntron Access 2 Prober, Huntron Workstation software, Keysight Spectrum Analyzer and Langer Near Field probes you are able to precisely measure a number of points on the signal path. Using the Huntron Workstation software, Virtual Test Points (VTP’s) are established on the circuit card as measurement locations. Once the VTP’s are set and the circuit card is stimulated to proper levels, the Huntron Access RF will measure and process the data for review. The Huntron Access RF will provide a minimum 10:1 improvement in probing time
