Functional testing
For applications where a bed of nails is either impractical, or where volumes are too low to justify it, Yelo can be used for edge connector functional testing. In this case, the link between the Unit Under Test (UUT) and the product edge connectors is made via a set of cables. Plug-in card fixtures can also be provided for this kind of testing.
To enhance diagnostic information, the operator can be prompted and guided to probe by hand. Averna can provide you with a large library of common tests for this guided probing, which includes visual pot setting aids.
PCB-level testing
One major benefit of the Yelo system range is the tight combination of in-circuit and functional tests. This allows for both types of testing to be combined without requiring large numbers of cards in the system. This also allows for flexible test strategies: you will be able to adjust the percentages of in-circuit and functional tests performed on the boards, with minimal reconfiguration.
Communications testing
The Yelo system is used by many companies as a communications test system. By simply adding the Telecommunications Test Card, you have the capability to test phones, modems, and many other line-based products. Further cards provide pulse code modulation, caller line identification, and PBX test functions.
Using the PCM Card, you can use the Yelo system to test digitally-based products. This will help you simulate the signalling on the internal side of many Private Branch Exchange (PBX) systems, and it will enable cost-effective testing of terminals, phones features, and the PBXs themselves.
Communications testing can be combined with bed of nails testing as part of a single fixture test strategy.
Testing assembled products
The Yelo system is an extremely cost-effective platform for automated testing of finished products. For high-volume production, Yelo can be used to automate the end-of-line testing on cased, finished products.
Yelo performs sophisticated, automatic switch, button, and LED display testing, handling a phone as an operator would.
