0

The MIL-HDBK-217 Module of ITEM ToolKit is a powerful reliability prediction program based on the internationally recognized method of calculating electronic equipment reliability defined in MIL-HDBK-217 (published by the US Department of Defense). This standard uses a series of models for various categories of electronic, electrical and electro-mechanical components to predict failure rates that are affected by environmental conditions, quality levels, stress conditions and various other parameters. These models are fully detailed within MIL-HDBK-217.

The MIL-HDBK-217 module provides a user friendly interface which allows the user to construct, analyse and display, system models using interactive facilities. Building a hierarchy and adding new components could not be easier. The program calculates the failure rates, including Mean Time Between Failure (MTBF), associated with new components as they are added to the system, along with the overall system failure rate. Project data may be viewed both via grid view or dialog view simultaneously, allowing predictions to be performed with a minimum of effort.

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.

Developed in collaboration with the Defense Micro-Electronic Activity (DMEA), the detail model allows the user to more accurately model the VHSIC, VLSI/CMOS component within the MIL-HDBK-217F analysis. This in turn leads to a more accurate Failure Rate and MTBF. The Detail Model goes into greater depth in the physical side of the component and looks into areas including: common; oxide; metal; hot carrier; contamination and package.

The ITEM ToolKit MIL-HDBK-217 module also supports the calculation of the MTBF and Failure Rate of equipment during non-operational periods. Based upon the RADC-TR-85-91 standard, this built-in calculation allows you to further refine your analysis.

The MIL-HDBK-217 standard is limited as to the types of connection technologies it supports. ITEM has added the ability for you to define custom connection technologies and their failure rates for use in the analysis. Any connection technology, such as sonic welding or gold-to-gold solder, with a known failure rate can be used.

ITEM ToolKit contains five 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), 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.
