“…A structured part selection and management methodology, which incorporates an "eyes-on, hands-off" approach, is a useful risk management tool during product development [22][23][24]. Part availability, part cost, part manufacturer quality, distributor quality, part performance, part reliability, assembly and life cycle obsolescence comprise the factors to be assessed.…”

Résumé -Facteurs de risques dans le secteur des équipements électroniques pour puits de pétrole et de gaz, comparés à d'autres industries électroniques -Le secteur des équipements électroniques pour puits de pétrole et de gaz est une industrie à faible volume, dans laquelle les temps de développe-ment et d'exploitation des produits sont considérablement plus longs que ceux des composants commerciaux utilisés pour leur fabrication. Les systèmes électroniques utilisés, en particulier pour le contrôle permanent des puits de pétrole, doivent fonctionner de façon fiable durant toute la vie du puits. Cela impose des contraintes particulières pour l'électronique utilisée. La garantie de fiabilité dans un environnement sévère et pendant une vie plus longue nécessite des dessins, techniques de qualification et d'essai, et contrôles de qualité adaptés. Tous ces facteurs génèrent des risques considérables pour les fournisseurs et les producteurs d'équipements électroniques destinés aux puits de pétrole et de gaz. Cet article présente une étude de ces facteurs de risques à prendre en compte dans la réalisation de produits destinés à la complétion et au contrôle continu de puits. Une comparaison avec d'autres industries électroniques à faible volume est présentée. Abstract -Risk Factors in Oil and Gas Well Electronics Compared to Other Electronic IndustriesThe oil and gas well electronics industry is a low volume industry in which the development and the operating life cycles of the electronic products used is considerably longer than those of the commonly available commercial parts used to build them. Oil and gas well electronic systems, especially the ones that are used for permanent monitoring of oil wells are required to function reliably at all times through-

“…• Functional operation is not implied in these ranges. 1 To ensure that all relevant aspects of product liability responsibility are considered, it is advisable to follow documented, controlled, and repeatable processes integrated with the parts selection and management programs [2], [9], [14], [23], [26]- [28]. 2 Some EIA/JEDEC documents ( [7], [8]) refer to absolute maximum ratings as absolute maximum "continuous" ratings.…”

Uprating is a process that assesses the capability of a part to meet the functional and performance requirements for an application in which the part is used outside the specified temperature range provided in the manufacturer's datasheet. This article discusses the use of uprating as a means to address obsolescence. The article begins by explaining the rationale and opportunities for using parts outside the specification range. The technical issues for using uprating to address obsolescence [obsolescence is known in the military community as diminishing manufacturing sources and material shortages (DMSMS)] are then presented. Finally, a case study is presented. Index Terms-Absolute maximum ratings (AMR).

PurposeThe paper presents an alternative solution to address part obsolescence. This paper discusses approaches to solve part obsolescence including an uprating approach. This paper also describes the methods to uprate parts, and demonstrates the practical application of the uprating approach in the form of a case study.Design/methodology/approachThis paper has been written to provide an understanding of the uprating approach to mitigate the problems caused by part obsolescence. The paper discusses the challenge faced due to part obsolescence, the temperature ratings for electronic parts, the uprating methods and finally explains the use of uprating to mitigate part obsolescence in the form of a case study. The part being uprated is a microcontroller unit used in many avionics applications. The case study describes a particular use of uprating and the return on investment.FindingsBased on the uprating approach, it was discovered that for the particular application, the commercially available plastic quad flat pack microcontroller could be used as a substitute for the “military” ceramic BGA version, which was discontinued by the manufacturer. It was discovered that there would be no problem with the commercial part's quality or reliability for the particular application. Parametric tests showed no evidence of instability of electrical characteristics over the uprated temperature range. There was substantial return on investment due to the use of uprated parts.Practical implicationsThis paper can help electronics manufactures deal with part obsolescence. This paper demonstrates the practicality of uprating parts. Uprating can save companies money by reducing the need for life‐time buys, substitution of parts and even redesign.Originality/valueThe paper provides an alternative approach to address the problem of part obsolescence. This paper shows that proper uprating leads to cost saving while continuing to provide reliable service.
