NIO USA Selects VayoPro-Test Expert Software

NIO USA Selects VayoPro-Test Expert Software


NIO USA, Inc selects and uses VayoPro-Test Expert software for efficient test strategy analysis so as to evaluate the defects coverage of different test methods (ICT, AOI, AXI…) and optimize the test plan, thus ensuring high quality and high reliability of final product. The selection will also enable fast programming of AOI/AXI test equipment to meet the requirement of intelligence, and simplify the AOI/AXI programming process to improve engineers’ work efficiency and enterprise’s flexible manufacturing capability.

Why choose VayoPro-Test Expert Software

VayoPro -Test Expert, as a requisite software for DFT analysis and fast programming of test equipment, could maximize the CAD data and BOM data to accurately analyze the DFT/ testing coverage, complete the ICT/ Flying probe/ AOI/ X-Ray test program in a short time and expand the data analysis of test fixture. With Test Expert, days of DFT analysis work can be shortened to several minutes’, and you can also get an elaborate testing& detecting program to extensively save the time of debugging and cost of test fixture.

Features of the solution:

Support all kinds of CAD data, such as Altium (*.pcbdoc), Cadence(*.val),Mentor(Neutral),Zuken,ODB++(*.tgz),IPC-2581(*.xml),Gerber, etc;

1. Import/validate BOM data and intelligently extract value and errors;

2. Support version comparison (CAD, BOM…), analysis of fixture reuse and report output;

3. Flexible parameter setting supports multiple component types (based on different customers, different product series,…);

4. Powerful nail selection rule assignment and result optimization;

5. Support execution of multiple nail selection rules at same time and results comparison;

6. Support Gerber silk-screen data validation;

7. Unique netlink technology, able to improve testing coverage;

8. Powerful DFT/testability report output (include 13 items) function;

9. High-efficiency testing strategy analysis and report output (to predict the coverage rate of main manufacturing defects);

10. Output of ICT, fly probe, AXI and AOI equipment program.
