Is electrical test a bottle-neck for productivity?

EXT maximizes your prober efficiency without sacrificing test accuracy. Speed up testing AND assure 100% test of your product with EXT.

Read it… Easily

Drag and drop input. A wide variety of inputs are supported, including RS-274X, RS-274D, ODB++, DPF, Drill, DXF.

Extract it… Accurately

Generate a netlist from your design data. Calculate adjacency, buried resistance and circuit resistance to include with output.

extScreenshotTest it… Quickly

Your test has to be quick and complete. EXT eliminates unnecessary test points without sacrificing a complete test. Maximize your prober efficiency with these EXT features:

  • Line of Sight adjacency offers the most efficient method of reducing the number of probe hits, and still gives you control over testing tolerances.
  • Eliminate unneeded test points on plane layers while assuring 100% test.
  • Include all the components and vias, components only, or end points of the nets.
  • Avoid recalculating test points for unchanged circuits during revision cycles by saving and restoring the test point database.

Save time and scrap with the proven reliability of EXT’s netlist extract, ability to compare nets between revisions, and graphical viewing of nets, test points, and data.

Ship it… Now!

Output to standard formats such as IPC-D-356A, MicroCraft, ATG, ECT, Probot, as well as RapiTrim Resistor Trimmer.
