▲'''Robustness validation''' is a skills strategy with which the [[Robustness (morphology)|Robustness]] of a product to the loading conditions of a real application is proven and targeted statements about risks and [[Reliability engineering|reliability]] can be made. This strategy is particularly for use in the [[automotive industry]] however could be applied to any industry where high levels of reliability are required
== History ==
Line 9 ⟶ 7:
At the beginning of the 1970s a relatively high failure rates of electronic components were tolerable in [[automobile]]s, because they replaced mechanical components, which had a much higher [[failure rate]]. The underlying failure rates of bimetallic [[Automotive lighting|flasher]]s were 10% per year and the lifetime of mechanical [[Circuit breaker|ignition contacts]] at 10,000 miles. With the increasing number of [[semiconductor]]s in [[control unit]]s, and the introduction of the first safety systems ([[anti-lock brakes|ABS]]) in the 70s had to be addressed. Already in 1975, the'' General Specification for IC's in Automotive Applications'' <ref>General Specification for ICs in Automotive Applications, SAE Recommendation, 1975</ref> as the first'' [[Society of Automotive Engineers|SAE]] Recommendation was issued'','' the 1978 SAE standard'' <ref>General Specification for ICs in Automotive Applications, SAE standard, 1978,</ref> was declared and adopted by major semiconductor manufacturers.
The establishment of the Automotive Electronic Council ([[Automotive Electronics Council|AEC]]) 1994 by [[Ford Motor Company|Ford]], [[Chrysler]], [[General Motors|GM]] - [[ACDelco|Delco]] was also the Starting point for the AEC-Q100 qualification process,<ref>Automotive Electronic Council's Stress Test Qualification for Integrated Circuits, AEC Q100, Rev. G, 2007, to [http://www.aecouncil.com/AECDocuments.html aecouncil.com]</ref> was based on the SAE standards.
Due to the development of [[automotive]] and the ever-increasing complexity of vehicles associated with the demands for lower error rates of this qualification process, this process to decide by nonspecific tests, to cover a wide range of possible failure mechanisms, but only on the functionality of the component is out of date.

Line 21 ⟶ 19:
Robustness Validation is used to assess the reliability of electronic components by comparing the specific requirements of the product with the actual "real life values". With the introduction of this methodology, a specific list of requirements (usually based on the [[Original Equipment Manufacturer|OEM]]) is required. The requirements for the product can be defined in the environmental requirements (mission profiles) and the functional requirements (use cases).
=== Mission
<!--[[Image:Potato_Diagram.jpg | thumb | Robustness for robustness validation based on the comparison of the application requirements, specification and technological limits of the component <ref name="RVHB_SC" />]]-->
Line 27 ⟶ 25:
The mission profiles describes the loads and stresses acting on the product in actual use. These are, for example, changes in temperature, temperature profile, vibration and working of electrical and mechanical fields, or other environmental factors. It is important to specify the relevant stressors in their nature, intensity and duration of exposure, as well as the mix as closely as possible. With these details it is possible, within specified accuracy, projections regarding reliability of application and its components in field applications.
=== Use
The use cases describe the nature and frequency of the operating conditions for which the product is designed. One should make sure that this addition to the normal operation of the possible cases of special operation and emergency operation. Intentional abuse is not included.
Line 35 ⟶ 33:
The lifetimes can be hedged by specific, tailored to the application and the failure mechanisms, determined tests. An essential process are [[End of life test]]s. From the distance of the requirements to the test results, the reliability and robustness of the device can be determined.
== Product
<!--[[Image:RV_flow.jpg | thumb | upright | Robustness Validation schedule of product development to mass production <ref name="RVHB_SC" />]]-->
Line 45 ⟶ 43:
In addition to the publication of the Handbook for Robustness Validation for semiconductor devices in 2007 the [[ZVEI]] in 2008, published the manual <ref>Handbook for Robustness Validation of Automotive Electric / Electronic Modules, ZVEI, 04/2008</ref> in which this procedure is described for the development and qualification of electronic control units in automobiles. There are also other activities in the field of sensors and electronic systems in the vehicle.
