TestWay & Test Expert - Two Popular DFT / Testability analysis software tool

1. intelligent software, pleasant work TestWay & Test Expert Two Popular DFT / Testability analysis software tool www.vayoinfo.com

2. Overview Along with the development of electronic manufacturing industry, DFT (Design for Testability or Design for Testing) has showed up its importance of guiding the designers to improve the testability of the designed circuit. Against such background, Test / DFT software comes out accordingly. Both Aster Technologies and Vayo Technology are founded by test professionals from electronics industry, and have worked out strong product for PCB test fields. Cycle time Reduction Business risk Reduction 95%

3. TestWay from Aster Technologies Aster Technologies, started relatively earlier, goes very deep in PCB test fields and developed its strong test product, TestWay. This board DFT & Test coverage analyzer has established a test structure based on a testability framework. The operating principles of TestWay is to import schematic or layout data and component model libraries, then to perform a topological analysis and symbolic simulation. The resulted topological and accessibility data would be used to check each rule. TestWay is indeed powerful in providing approaches for DFT and testability Cycle time Reduction Business risk Reduction 95% analysis, while to conduct the complete set of testing process is still somewhat complicated for engineers and it requires more data import.

4. Test Expert from Vayo Technology Vayo Technology has chose another way to its product strategy. Vayo emphasizes more on the intelligence and ease-of-use of software tools. A software should come to ease people’s work and promote efficiency, not to complicate the task. With 17+ years’ devotion to NPI solution, Vayo Technology has worked out VayoPro - Test Expert software. VayoPro - Test Expert not only stands out in DFT/testability analysis, but highlights intelligence and low complexity, achieving the goal of tool supporting people. Test Expert supports import of all popular CAD data and by intelligently integrating with testability requirements, Cycle time Reduction Business risk Reduction 95% performs a comprehensive DFT / testability analysis as well as test strategy analysis. The testability report generated by Test Expert provides a rich content with more than 13 categories, including Accessible Net Report, Insufficient Probes (accessible net), Parallel Report, NC Pin List, Unstable Test Point, etc.

Test Expert: testability, strategy & program generation Powerful & flexible nail selection rules Comprehensive DFT/testability analysis & report Advanced test strategy analysis & report Fast ICT/AOI/AXI/AOI programming DFT/testability & strategy DFT/testability & strategy comprehensive analysis, increase coverage Nail optimization, reduce inline debug cycle Fixture reuse analysis, save cost Fast programming, reduce NPI cycle Leverage NPI reaction capability, save labor cost     

6. Test Expert from Vayo Technology Comparing with other DFT/testability software, VayoPro - Test Expert comes with those competitive advantages: mask layer validation via extra Gerber data source, virtual nets merge for higher testability, backdrill identification, batch nail offset for flying probe tester, etc. Cycle time Reduction Business risk Reduction 95%

7. Profile of Vayo Technology Founded in 2005, Vayo Technology maybe starts relatively late, its core founder members are all technical experts from electronics industry and believes ‘intelligent software brings pleasant work’. With 17+ years’effort and devotion to NPI/DFT/DFA/CAM software solutions for electronics industry, Vayo Technology’s NPI solution like 3D DFM/DFA analysis, DFX execution system, stencil know-how digitalization, DFT / testability & strategy analysis, SMT specialized CAM tool, visual aids work instruction, board view & fast query, Gerber view & conversion,... has gained worldwide recognition among the electronic industry. Up to now, Vayo owns 25+ patents and has been recognized by 500+ Cycle time Reduction Business risk Reduction 95% customers from 20+ countries worldwide. We are proud to announce that VayoPro - Test Expert has been selected by Flex / Venture / Jabil/ Sanmina / IMI / Benchmark / OSI / Katek / Paramit / Intel / GE / Keysight / Intuitive / Bosch and so on.

9. Customer Testimonials “We have been impressed with the product capabilities, their communication and commitment to supporting their products is truly world class.” “Vayo tool is very intuitive and user- friendly. You can match parts and pds visually and new pds can be created easily. Part Data Editor and Parts Verification ensures every location has correct part, size and orientation.” “Vayo tool has been extremely useful for us in identifying assembly issues much ahead of the actual assembly process. This has drastically reduced holdups in the production line, increasing our productivity.” “From years of experience with DFT and CAD SW's, VayoPro-Test Expert is the best. It is fast, accurate and easy to use. Its DFT report is very comprehensible for our customers.” “We started (cooperating) with Vayo at year 2009 and has not been turning back since then. What differentiate Vayo from the rest is their willingness to listen to their customer’s needs with fast respond.” “I was impressed by Vayo NPI tools, it is really world class solutions in the industry!“ Kent Kim Vice President Murad Kurwa Senior Vice President Eddie Chang SMT engineer David Kim Atar Mittal General manager CHIA Kar Lin Test Development Manager Head of Innovation Centre “From the selection of Vayo solution on the year of 2007, we are able to support these data source whatever we receives what kind of data from new customer, and then quickly completes placement programming.” “By introducing Vayo‘s intelligent software tool it is now possible for operators to perform data conversion requiring little skill, while reducing the work time required to one fifth of what it was.” “Accelerator allowed us to reduce a lot “The accelerator function helps us a lot on component placement orientation, we don't need to do mapping Gerber file and checking placement orientation one by one any more.” “With VayoPro-Test Expert solution and “Communication is important for every the quantity of mistakes in the projects great support of Vayo team, we could filed, good conversation shall bring and the time required for their accelerate our product review for DFT joyful experience, Vayo is such preparation.” (ICT/Boundary).” company we worked with!” Sergei Fedorov Product Director Mohamad Azlan Ahmad, GPEO-M PE, Tong Chang Tony Zhou CC Cho Mitsuo Imai General manager Production Associate Manager CEO, IPC board director Sr. Manufacturing Engineer
