19、Foreword The CENELEC Electronic Components Committee (CECC) is composed of those member countries of the European Committee for Electrotechnical Standardization (CENELEC) who wish to take part in a harmonized System for electronic components of assessed quality. The object of the System is to facili

20、tate international trade by the harmonization of the specifications and quality assessment procedures for electronic components, and by the grant of an internationally recognized Mark, or Certificate, of Conformity. The components produced under the System are thereby acceptable in all member countr

21、ies without further testing. This European Prestandard was prepared by CECCWG9, Integrated Circuits. The text of the draft based on document CECC(Secretariat)3117 was submitted to the formal vote; together with the voting report, circulated as document CECC(Secretariat)3251, it was approved by CECC

28、quantities cannot be fully identified in a QA system and do not lend themselves to cost effective sampling systems for assessed quality. Qualification Approval or Capability Approval can be used in “Product Oriented Manufacture” (POM) processes whereas “Design Oriented Manufacture” (DOM) processes r

29、equire the adoption of a non “Product Oriented” Qualification System. This has resulted in the consideration of a new standard for ICs and ASICs based on QA systems already in use in the CECC and National organizations. The new system being based on built-in quality from the design phase to the fabr

30、ication. This is the aim of the so called “QML” US approach, this forms the basis of the current standard which proposes European QML (EQML: European Qualified Manufacturing Line) as a third way for implementing Quality Assurance in Europe (as an alternative to QPL and Capability Approval systems).

31、This approach puts the emphasis on: application of the Total Quality Management principles; built-in quality; constant improvement plan for Quality and Reliability; responsibility of the manufacturer/design centre for quality; use of statistical process control (SPC) techniques, where applicable, fo

32、r process quality management and improvement; delivery of suitable components with the suitable quality for all the market segments; changes to be permitted, more so they are recommended as a fundamental way of improving process quality. 1.2 Scope This specification establishes the general requireme

33、nts for components and the quality and reliability assurance requirements which shall be met for their acceptance within Europe. Detail requirements, specific characteristics of components and other provisions which are sensitive to the particular use intended shall be specified in the detail specif

34、ication. The foundation of the manufacturing process approval is the basis of Total Quality Management (TQM) within the manufacturing environment. TQM requires that all levels of management be actively involved in the commitment to quality. A Technology Review Board (TRB) shall be established to con

35、trol, stabilize, monitor and improve the qualified technology. The TRB shall develop a Total Quality Management Plan that outlines how the manufacturing operation for a given manufacturing flow is controlled, monitored and improved throughout its entire “Life Cycle”. Key aspects of this plan are the

36、 establishment of Statistical Process Control, Field Failure Return Programmes, Corrective Action Procedures, Quality Improvement and any other approaches required to control and improve product quality, reliability and service. These requirements are detailed in this document. Quality assurance req

37、uirements outlined herein are for all components built on a manufacturing line which is controlled through a manufacturer Total Quality Management (TQM) programme and has been certified and qualified as per the requirements herein. The manufacturing line shall be a continuous process flow for all co

38、mponents. A single level of product assurance is provided for in this specification. The certification and qualification requirements found herein are the requirements which allow manufacturers to be registered in the list of qualified manufacturers (EQML). The manufacturer Process Qualification lea

39、ding to EQML requires a manufacturing line or technology flow certification and qualification. On-going monitoring techniques will be used to maintain EQML status. The manufacturing line consists of facilities and procedures appropriate to accomplish the design, specific tool making, fabrication, ma

40、terial procurement, testing, packing and delivery of components and the customer support (see Figure 1). After registration on the EQML list, the manufacturer shall continually meet the baseline certified/qualified procedures, the TQM Programme, the TRB, the Status Reporting and specific requirement

41、s for all EQML products of the appropriate technology. The tests which shall be performed on each product built are defined in the relevant CECC specification.ENV 190000-6:1994 4 BSI 12-1999 Figure 1 Example of manufacturing line flow diagramENV 190000-6:1994 BSI 12-1999 5 Further, this ENV describe

42、s the procedures and requirements for EQML Registration. Registered manufacturers will be able to produce components without the need for extensive end-of-manufacturing qualification testing and quality conformance inspections on each component. The reduction of the end-of-manufacturing testing will

43、 be replaced with in-line monitoring and testing and Statistical Process Control (SPC). Also, surrogate devices, such as the Standard Evaluation Circuit (SEC) will be used to assess the technologys reliability. Introduction of this methodology shifts the emphasis from the need of individual componen

44、t Qualification Approval to process (technology) certification and qualification and thereby will accelerate the component insertion cycle of high quality and reliable components. The requirements defined by this ENV provide a baseline for all manufacturers. As the technology matures and reliability

45、 and quality data are gathered, the manufacturer through the TQM programme and Technology Review Board (TRB) may modify, substitute or delete tests. Notification of such actions shall be detailed in the Status Report submitted to the ONS and related documents shall demonstrate the efficiency of such

46、 actions and shall be accessible to the ONS. The procedure for manufacturer Process Approval is accomplished in two stages: certification and qualification. The process of certification is the recognition of evidence by the ONS that the manufacturer is capable of producing and delivering components

47、of high quality that comply with the requirements of this document. Qualification is the actual demonstration of the certified manufacturing line capabilities by producing “first pass” components complying with the requirements of this document or related specific documents and the device specificat

48、ion. In Figure 2, each task can be individually reviewed, but shall be certified as a flow. The only process flow which would be qualified (EQML listed) would be the group of tasks which are linked together and validated during approval. The letters “A” and “B” indicate an EQML task where qualificat

49、ion testing has qualified a complete path. The other paths are not EQML approved until certification and qualification testing of the processes has been completed. NOTEIn the case of a task being subcontracted to a third party, the company involved shall also be certified for the line involved. This implies similar requirements for the subcontractor such as TRB, line capabilities etc. and interface on each side under TRB control. TQM does not stop when a manufacturer is listed on EQML. This ENV identifies the necessary screening which
