http://dbpedia.org/ontology/abstract Burn-in is the process by which componentsBurn-in is the process by which components of a system are exercised before being placed in service (and often, before the system being completely assembled from those components). This testing process will force certain failures to occur under supervised conditions so an understanding of load capacity of the product can be established. The intention is to detect those particular components that would fail as a result of the initial, high-failure rate portion of the bathtub curve of component reliability. If the burn-in period is made sufficiently long (and, perhaps, artificially stressful), the system can then be trusted to be mostly free of further early failures once the burn-in process is complete. Theoretically, any weak components would fail during the "Burn In" time allowing those parts to be replaced. Replacing the weak components would prevent premature failure, infant mortality failure, or other latent defects. When the equivalent lifetime of the stress is extended into the increasing part of the bathtub-like failure-rate curve, the effect of the burn-in is a reduction of product lifetime. In a mature production it is not easy to determine whether there is a decreasing failure rate. To determine the failure time distribution for a very low percentage of the production, one would have to destroy a very large number of devices. By stressing all devices for a certain burn-in time the devices with the highest failure rate fail first and can be taken out of the cohort. Thus by applying a burn-in, early in-use system failures can be avoided at the expense (tradeoff) of a reduced yield caused by the burn-in process. When possible, it is better to eliminate the root cause of early failures than doing a burn-in. Because of this, a process that initially uses burn-in may eventually phase it out as the various root causes for failures are identified and eliminated. For electronic components, burn-in is frequently conducted at elevated temperature and perhaps elevated voltage. This process may also be called heat soaking. The components may be under continuous test or simply tested at the end of the burn-in period. There is another use of the term by some audiophiles, who leave new audio equipment turned on for multiple days or weeks, to get the components to achieve optimal performance. However, many debates have arisen about the benefits of this practice.risen about the benefits of this practice. , 煲机(Burn in, or Run in, Break in),广州方言。是系统的零部件在放在整机运行(服务)前,进行“锻炼”的过程。这个测试过程将在监控的条件下,使各种错误产生,从而产品的负载能力能够由此建立。 , Le déverminage est une procédure permettanLe déverminage est une procédure permettant de tester les éléments d'un système avant d'entrer en service (et souvent, avant que le système ne soit complètement assemblé avec ces éléments). Cette procédure de test consiste à forcer le déclenchement de certains défauts ; en l’occurrence les incidents liés au rodage du système (aussi nommée « défauts de jeunesse ») dans des conditions de surveillance permettant l'établissement de l'origine du défaut. L'objectif est de détecter les éléments pouvant générer un défaut durant leur période de rodage, période durant laquelle la probabilité d'incident est élevée comme cela est présenté sur la courbe en baignoire. Si la durée de déverminage est suffisamment longue (et éventuellement, artificiellement stressante), le système peut être considéré comme suffisamment fiable et déchargé d'une grande part des risques de défaut de jeunesse une fois cette procédure achevée. En théorie, tout composant peu fiable devrait générer un défaut durant le déverminage, permettant ainsi son remplacement afin de prévenir les défauts prématurés, les défauts de jeunesse ou tout autre défaut latent.s de jeunesse ou tout autre défaut latent. , التسخين (أو التنجيذ ) هي العملية التي يتم التسخين (أو التنجيذ ) هي العملية التي يتم ممارستها على مكونات النظام قبل وضعها في الخدمة. وهذة العملية تقوم بإجبار الأخطاء على الحدوث تحت ظروف معينة خاضعة للإشراف حتي يتم فهم مسار العملية. والهدف من تلك العملية هو تحديد المكونات التي من شأنها أن تسبب خطأ نتيجة ارتفاع احتمالية حدوث الخطأ كما هو موضح في منحني معدل الإخفاق المستخدم لقياس الاعتمادية. وكلما كانت فترة استمرار العملية طويلة بما فية الكفاية، كلما أصبحنا أكثر يقينا من اعتمادية النظام وكلما قلت الأخطاء التي يمكن أن تحدث في البداية. نظريا يتم استبدال أي مكون ضعيف من شأنة أن يسبب أي خطأ في مسار العملية. وبذلك يتم تقليل حدوث الأخطاء، وحالات الفشل، أو العيوب الكامنة الأخرى. عندما يتم توسيع مدي ( عمر / زمن ) الضغط في الجزء المتزايد من منحني حوض الإستحمام ( منحني معدل الإخفاق )، يكون تأثير هذة العملية سلبي وهو الحد وتقليل عمر المنتج. في عمليات الإنتاج ليس من السهل تحديد ما إذا كانت نسبة الخطأ تتناقص. لأنه لتحديد توزيع وقت الفشل لنسبة قليلة من الإنتاج، يتم تدمير عدد كبير جدا من الأجهزة. وبالنسبة للمكونات الإلكترونية، فغالبا ما تجري هذة العملية في درجات حرارة عالية وتحت جهد عالي. ويمكن تسمية هذة العملية بتمرغ الحرارة أو الغطس الحراري. حيث أن المكونات تكون تحت الاختبار المستمر.حيث أن المكونات تكون تحت الاختبار المستمر. , Burn-in (qualcosa di simile al rodaggio peBurn-in (qualcosa di simile al rodaggio per le parti meccaniche) è il processo al quale sono sottoposti i componenti di un sistema prima di essere messi in servizio (e, spesso, prima che il sistema sia stato assemblato completamente con quei componenti). L'intenzione è di individuare quei particolari componenti che si guasterebbero a seguito della cosiddetta mortalità infantile, ovvero, durante la parte iniziale, ad alto tasso di guasto, della curva a vasca da bagno relativa all'affidabilità dei componenti. Se il periodo di burn-in è sufficientemente lungo (e, eventualmente, reso artificialmente stressante), si può ritenere in modo affidabile che, una volta completato, il sistema ad esso sottoposto sia quasi totalmente privo di ulteriori guasti iniziali. La condizione più importante perché il burn-in sia efficace, è che il tasso di guasto segua una curva a vasca da bagno, ovvero, che ci siano un numero notevole di guasti iniziali, con un tasso di guasto in discesa dopo il periodo iniziale stesso. Producendo stress in tutti i dispositivi per un certo lasso tempo, i dispositivi con il tasso di guasto più alto saranno i primi a guastarsi, e potranno essere eliminati dalla popolazione. I dispositivi che sopravvivono allo stress applicato, avranno una posizione più avanzata nella curva a vasca da bagno (avranno un tasso di guasto più basso). Pertanto, applicando il burn-in, i guasti del sistema nella fase iniziale dell'utilizzo possono essere evitati, al costo (compromesso) di un ridotto tempo di utilizzo, a causa della durata temporale del processo di burn-in stesso. Quando l'equivalente dello stress, in termini di vita utile, è esteso alla parte crescente della curva di tasso di guasto a vasca da bagno, l'effetto del burn-in è la riduzione della vita utile del prodotto. In una produzione stabile, non è facile determinare se vi sia una diminuzione del tasso di guasto. Per determinare la distribuzione del tempo di guasto per una bassa percentuale della produzione, si dovrebbero distruggere un gran numero di dispositivi. Perciò, quando possibile, è meglio eliminare la causa a monte dei guasti iniziali, rispetto all'eseguire un burn-in. Per questo motivo, un processo che usa inizialmente un burn-in dovrebbe, alla fine, escluderlo, nel momento in cui le varie cause di guasto vengono man mano identificate ed eliminate. Per i componenti elettronici, il burn-in è spesso condotto a temperatura elevata, e a volte a tensione elevata. Questo processo può anche essere chiamato heat soaking. I componenti potrebbero essere sotto una forma di test continuativo, o semplicemente verificati alla fine del periodo di burn-in. C'è un altro uso del termine, da parte di alcuni audiofili, che lasciano i loro nuovi apparecchi audio accesi per molti giorni o settimane consecutivi, per fare in modo che i componenti raggiungano le migliori prestazioni. Comunque, il dibattito è aperto, a proposito dei possibili benefici di questa modalità di utilizzo.i benefici di questa modalità di utilizzo. , 고온 검사는 프로세스인데 제품 출하하기 전(가끔 콤포넌트로 완벽하게 조립되기 전)에 수행한다. 이 시험은 목적은 시스템 신뢰성 (bathtub curve)의 초기에 높은 고장율을 갖는 주기 동안에 고장을 발생시키게 함으로써 어떤 부품이 문제가 있는지를 감지한다.
