PCB Functional Tester


Functional testing of printed circuit boards, sub assemblies and finished products

A compact bench-top system, the Yelo Testpoint combines bed of nails in-circuit testing with functional testing to validate that your product hardware is free of defects. It has easy-to-use software that allows you to program and monitor your own test, making it the most convenient and flexible product tester on the market.

Three unique models to choose from

Flexible and Functional

Easily manage tests with Yelo Test Executive (YTE) software V.5.0

Distinctive and space-saving design.

Identifies and screens out defective devices

Test printed circuit boards, sub assemblies and finished products

Choose the Right System For You


This system has been designed for applications that require minimal testing such as fire alarms and carbon monoxide monitors.


Ideal for performing functional and in-circuit testing on applications such as defibrillators with low node counts.


The workhorse of the Yelo system range. It provides the resources needed for testing PCB assemblies.

System Range



Yelo Tespoint is your answer to milti-purpose functional testing. Thanks to its improved flexibility, you can adapt it to test different types of products and use it to perform different types of product tests to make sure your product is functioning properly before it reached your customers. 

You can create and program your own tests. We will provide you with a full range of test cards as well as Yelo Test Executive (YTE) Software, which makes programming tests easier than its ever been. Full documentation and optional training is provided to make sure you get the most productivity from your system.

We include Yelo Test Environment (YTE) v5.0, which is the easiest way to manage your tests with a user-friendly interface and receive clear, easy-to-read graphical repots automatically once testing is completed.
If you are new to functional testing it can be difficult to get the most effective results without the proper implementation. But we are here to help you every step of the way. Our experienced engineers will train you on how to program the equipment and software for your product under test and will be available to answer any questions/problems you have before and duting your testing process - so that you get maximun productivity from your system.
  • Up to 15 user slots

  • Optional central measurement system

  • Bed of nails fixture interface

  • Built-in power supplies

  • User-friendly, menu-based software

  • Bench-top station in a compact chassis

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. Yelo can provide you with a large library of common tests for this guided probing, which includes visual pot setting aids.
One major benefit of the Yelo Testpoint 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 boards, with minimal reconfiguration.

The Yelo Testpoint 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 Testpoint 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, phone features, and the PBX itself. Communications testing can be combined with bed of nails testing as part of a single fixture test strategy.

Testing assembled products, the Testpoint 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.
