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.
