Q: What are the primary differences between the single head Access Probers and the dual head Access DH?
A: The Access DH allows you to probe between two specific points whereas the single head prober requires a common connection used for the "return" line. The Access DH was designed as an open architecture system where the user can setup testing processes of their own design. The Access DH is built on its own cabinet with space underneath for additional test equipment.
Q: What types of test hardware can be connected to an Access DH Prober?
A: The Huntron Workstation software supports Huntron Trackers (Tracker 3200S and Tracker Model 30) and selected conventional test instruments (see the Workstation Software page for a list). Other test instrumentation can be connected to an Access DH Prober and controlled using Huntron Remote Control or custom applications developed using the Hardware SDK.
Q: How fast is the Access DH Prober?
A: The probing speed depends on how the Prober is being used. If it is being used to take measurements, the speed in affected by how long it takes to capture the measurement. In general, you will be able to probe across two points approximately every two seconds.
Q: How accurate is the Access DH Prober and how close can the probes get to each other?
A: The Huntron Access DH is very accurate. The minimum step resolution is 0.4 microns with an accuracy of +/- 20 microns. This is more than accurate enough to probe very small lead spaced devices such as the 0.4mm surface mounted ICs. Currently, the minimum spacing between the two probes is 0.05" (1.27mm) when 50mil probe holders are installed.
Q: Can I use CAD data to develop a test routine?
A: Yes. Optional software is available to assist you in using your CAD data to create tests in Huntron Workstation. You can find more details by visiting the Workstation Software page (please see CAD Tools datasheet).
