38、 to the specified outline or base drawing.2.5.2 Type designationWhen the type designation is marked on the component, it shall be given preferably in letters and figures, or with a colour code when specified in the detail specification. Colour codes may be given in the sectional specification.2.5.3

39、Manufacturers name or trade markIf the manufacturers name or trade mark does not enable traceability to the manufacturing factory, a factory identification code shall also be used.2.5.4 Inspection lot identification codeThis is given in ISO Standard8601 for the week, preceded by the last two digits

40、of the year (example:9145=45th week of1991). When marking-space on the device is restricted, the first digit of the year may be omitted (example:145=45th week of1991) when specified in the detail specification. It is the date that the lot was submitted for inspection. When more than one lot of a typ

41、e is submitted for inspection within the same week, an inspection lot identification suffix, such as a letter, shall be used to identify each successive lot.2.6 Categories of assessed qualityThis specification provides for three categories of assessed quality. The devices are grouped in an identifie

42、d and date-coded inspection lot, which is tested to the specified quality categories. The AQLs or LTPDs associated with the same inspection group may vary for each category and shall be as specified in the detail specification.The minimum requirements of the categories are as follows: The sectional

43、specifications shall define the minimum requirements for each category. A detail specification may contain additional requirements, including screening, to those given in the generic, sectional or blank detail specification.2.7 ScreeningA screening is an examination or test applied to all devices in

44、 a lot.Category I In which the type meets the requirements of qualification approval to categoriesII orIII. Each lot meets the inspection requirements of Group A which includes functional tests. Every three months, one lot meets the inspection requirements for solderability. Annually, one lot meets

45、Group B and Group C inspection requirements.Category II In which the lot meets the inspection requirements of Group A and Group B on alot-by-lot basis and of Group C on a periodic basis.Category III In which the lot is100% screened and meets the inspection requirements of Group A and Group B on a lo

46、t-by-lot basis and of Group C on a periodic basis.BS IEC 60747-10:1991IEC 60747-10:1991 (E) BSI 20114When required by the detail specification, all devices in the lot shall be screened by submitting them to one of the sequences given in the relevant table of the sectional specification and all defec

47、tives removed. Other sequences not specified herein are applicable only in case the above sequences are not correlated or in contradiction with recognized failure mechanisms. When a part of the screening process as given in the relevant table of the sectional specification forms part of the manufact

48、uring process in the prescribed sequence, these procedures need not be repeated. For the purpose of this specification, burn-in is defined as thermal and electrical stress applied to all devices in a lot for a specified period of time for the purpose of detecting and removing potential early failure

49、s.2.8 HandlingSee IEC Publication747-1, chapterIX.Adequate warning shall be displayed in the case of harmful products (e.g.BeO).3 Quality assessment proceduresQuality assessment comprises the procedure for obtaining qualification approval as defined in subclause3.5, followed by quality conformance inspection on a lot-by-lot basis (including screening if required) and on a periodic basis as qualified in the detail specification.The quality assessment tests are subdivided into Group A, B and C tests; these are performed lot by lot or periodically (a
