Locate Short Circuits using a Milliohmmeter

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.
