IEC-61709 Electronic Reliability Prediction

The IEC-61709 module supports the reliability prediction methods based on the European Prediction Standard IEC-61709. This module is predominantly based on the Siemens Prediction Standard SN-29500, as well as conforming to section 19 for PCBs and section 20 for the Hybrid Circuits within the European Prediction Standard IEC-62380 (RDF 2000/UTE C 80-810).

The IEC-61709 module provides models for reliability prediction of electronic components, printed circuit board and equipment extrapolated of failure rates from referenced  conditions to other operating conditions that permits the prediction of failure rates at assembly level.

ITEM ToolKit platform offers the linking of source failure rate data to and from other prediction modules as well as having powerful import/export capabilities. The IEC-61709 module can be used to obtain failure data from other ToolKit prediction modules as well as sourced failure rates, either direct from the component manufacturers or organisations who have failure rate databases that contain collected field reliability data. This data will provide the base failure rate for the ITEM ToolKit IEC-61709 module, which along with the user defined application parameters specified in the IEC-61709 standard, would provide the complete reliability prediction analysis based on the IEC-61709 module.

Library management, import and export facilities are also provided. Quality user-configurable reports are produced by the program automatically. In addition, data may simply be dragged and dropped into Microsoft applications such as Word, Excel, Access etc. allowing a wide range of additional customised reports and charts to be produced.

ITEM ToolKit's Reliability Prediction Modules

ITEM ToolKit contains six modules for performing reliability prediction (MTBF) analysis. These modules conform to MIL-HDBK-217 F Notice 2, Telcordia (Bellcore) TR-332 and SR-332, IEC 62380 (RDF 2000), IEC 61709, China 299B GJB/z 299B (electronics), and NSWC 06 (mechanical) and share many common features and capabilities.

Each reliability prediction module is designed to analyse and calculate component, sub system and system failure rates, including Mean Time Between Failure (MTBF), in accordance with the appropriate standard. After the analysis is complete, ITEM ToolKit's integrated environment comes into its own with powerful conversion facilities for transferring data to other modules of the program. For example, transfer your MIL-217 project data to FMECA or your Telcordia project to RBD. These powerful facilities transfer as much of the available information as possible, saving you valuable time and effort.

ITEM ToolKit's Multi Document Interface allows several projects or libraries to open at the same time. This valuable feature comes in especially handy when it is necessary to transfer data from one project (or library) to another.

Users can construct hierarchical breakdowns of systems with no restrictions on block numbers or levels of indenture. As new sub blocks and components are added, ITEM ToolKit automatically recalculates all dependent failure rates to take account of new information.

Powerful global editing facilities are available for performing "what if" evaluations. These facilities enable you to experiment with temperature, environmental and stress settings and see how your system performance will vary.
