The Easiest Test Strategy (Structural) Analysis for PCBA Testing

Time:2022-05-05Views:435

As we all know that PCBA testing is one of the most important procedures before mass production of the new product, it’s not practical to run every test moneywise and timewise. Thus, Test strategy is essential for engineers to decide which test to run.

Most of DFT strategy analysis software could achieve nail access analysis, but not each of them can achieve test strategy. Some people call it structural test, you can find similar service provider in the industry.

For PCB test software, both Vayo Technology & Aster technologies could achieve test strategy (structural test) analysis. The industrial solution provider Aster technologies goes very deep in test strategy (structural test), while Vayo chooses a different way to its product strategy.

Instead of developing deeper level and complex product function which is time consuming for engineers to use, Vayo developed intelligent, automatic, error-proof tool, which could simplify the work with flexibility and increase efficiency for engineer’s daily work. By adhering to the vision of “intelligent software brings pleasant work”. Vayo has offered most simple ways for test strategy analysis in the industry, and it just take 20- 40 minutes to generate a comprehensive test strategy report.

VayoPro – Test Expert offers DFT / Test strategy with comprehensive information. Defects coverage is estimated through different test approach such as ICT, AOI, AXI, …

Major manufacturing (PCB assembly) defects like open circuit, short circuit, wrong polarity, missing component, wrong parts score will be shown as listed.

Meaning of the score in DFT strategy report :

1  means the defect item can be detected in the corresponding test stage

0  means the defect item cannot be detected in the corresponding test stage

-1  means the defect item is not available for this DFT test.

Defects coverage summary (open, short, missing, …) for different test stages.

Parallel Net list is also included for engineer’s reference.

Traditionally, it is time consuming to get a DFT strategy report, usually taking hours or even days to accomplish. With VayoPro – Test Expert, it only takes 20- 40 minutes to generate a DFT /Test strategy.

Engineers who are using VayoPro – Test Expert have to say it makes test strategy easy and efficient.

For data input, VayoPro – Test Expert supports most existing PCB CAD and can intelligently identify CAD format.

Compared with other DFT/testability software, VayoPro-Test Expert also stands strong with competitive advantages like: Validating mask layer via extra Gerber data source, virtual nets merge for higher testability rate, backdrill identification, batch nail offset for flying probe tester, not to mention the ease-of-use and immediate support (response <8 hours for urgent cases).

Up to now, VayoPro-Test Expert has been selected by Flex / Venture / Jabil / Sanmina / IMI / Benchmark / OSI / Katek / Paramit / Intel / GE / Keysight / Intuitive / Bosch …

We have also received some favorable comments on this intelligent DFT strategy analysis tool.

“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.” said by David Kim, Test Development Manager from Paramit.

“With VayoPro – Test Expert solution and great support of Vayo team, we could accelerate our product review for DFT (ICT/Boundary).”, said by Tong Chang, Production Associate Manager from Supermicro.
