Test and Design for Test (DFT) Software for Electronics Manufacturing
Test Expert is the most widely used test programming and design for test (DFT) software application in the electronics manufacturing industry today. Test Expert (formerly Fabmaster) is a fully integrated solution that allows electronics manufacturers to go from design to test and inspection in a matter of minutes or hours, rather than days. With its fast, user-programmable nail/probe selection routine and complementary interactive tools, Test Expert offers complete flexibility and control during fixture design for in-circuit test (ICT) and advanced flying probe selection.
Test Expert’s workflow-driven user interface allows you to follow all the steps required for full programming and fixture generation, or just the steps necessary for fast DFT results. The workflow guides you through the test/inspection processes starting with computer-aided design (CAD) data and bill of materials (BOM) input, through probe selection and fixture design, to program generation. This ensures that the same, tested procedures are used repeatedly to reduce errors and improve accuracy and productivity.
Design Transfer Process
- The greatest range of CAD input formats supported in the industry today (over 65 formats)
- Fast CAD/BOM recovery for accurate PCB visualization including part shapes, pads, drills, fiducials and net traces
- Available Gerber reverse engineering software
Perform Upfront DFT Analysis
- Perform fast, upfront DFT on any CAD design before handing it off to manufacturing
- Easy-to-set fixture and test design algorithms make it simple to determine the actual testability of any PCB
- Flexible fixture design setups can be saved and re-used
- Quickly compare cost versus test coverage for different test technologies
Test Program Automation
- Standard outputs for a wide range of test systems including ICT, flying probe, X-ray and automated optical inspection (AOI) machines
- Manage variants and generate a universal fixture design that can be used to test all product variants within a family
- Display the differences between variants and specify which attributes are relevant to each variant
Probe Selection/Fixture Design
- Define rules for automatic nail/probe selection for in-circuit and flying probe testers
- Select probes and design the fixture before a single bare board has been manufactured
- View problem nets and decide on corrective actions using accessibility report with CAD graphics
- Manage dense boards with a global probe offset tool
Interactive nail/probe editor
- Add, move, and delete nails/probes with an interactive editor
- Automatically check that manual changes conform to established nail rules
Import of native CAD from 65 different platforms including nets and traces
• Program generation for 75 different ATE platforms including the leading ICT, AOI, Flying Probe and x-ray machines
