Functional Test Development

Functional testing is a quality control tool used to check that electronic products meet their performance specifications. Functional test equipment is as varied as the tested products, and requires custom designs. The equipment must be robust, and the tests must be reliable. 

Abtest Limited offers turnkey solutions to functional test needs.

Software Integration

We can integrate into Test Executives such as TestStandT.

All test software is developed in a manner that allows operational variables to be modified with minimum programming knowledge.

Experience

Abtest functional test solutions have been implemented in many industries including:

• Electronic
• Automotive
• Telecoms
• Medical

Abtest and National Instruments

Abtest recognises the need to use quality, well developed and well supported modules within its functional test solutions, therefore whenever required Abtest uses National Instruments products.  Abtest are Associate Members of the National Instruments Alliance Programme, and as such our Test Development Engineers are National Instruments trained in all aspects of software development and implementation.

Documentation

The documentation will contain: block diagrams to indicate the structure of the system; top level schematics showing the interconnections between sub-systems; circuit diagrams of each sub-system; bills of materials, including suppliers and order codes; fixture interface design and wiring lists.  The documentation also includes:  a description of the system; operating instructions; maintenance recommendations and information; troubleshooting notes where appropriate; risk assessment of hazards identified, and the control steps taken to minimise the hazards.

User Interface

The test hardware and software are designed to provide an intuitive and simple-to-use user interface.  User inputs and decisions are minimised wherever possible. A "go-nogo" result indication is preferred, and test results can be printed and logged as required.

Hardware

The hardware is custom designed for each application.  Fixturing allows connection by bed-of-nails if appropriate, or manual connection may be necessary.  Fixtures may be pneumatic or vacuum operated under the control of the test software, or may be mechanically operated by the tester.  Loads and interfaces may be simulated, or a substitution method may be used. 

Diagnostics and Maintenance

Hardware and software are designed to facilitate proper maintenance of the test equipment, and diagnostic tools are incorporated to aid with housekeeping and troubleshooting.  Self-test diagnostics may be used where appropriate, and maintenance scheduling may be incorporated into the test software.

Endurance Testing

Functional test equipment can be built for endurance testing systems or components.  The equipment may be fitted inside an environmental chamber in order to test under a wide range of climatic and dynamic conditions.  This can all be carried out  at Abtest Limited to UKAS accredited standards.
