JEDEC Standard No. 671B -i- COMPONENT QUALITY PROBLEM ANALYSIS AND CORRECTIVE ACTION REQUIREME
10、NTS (INCLUDING ADMINISTRATIVE QUALITY PROBLEMS) Introduction Suppliers of electronic components strive to ship products with zero defects. Despite their best efforts, problems may occur from time to time. When that happens, timely and accurate root cause failure analysis and the establishment and ma
11、intenance of an effective corrective action system are of critical importance to an electronic component suppliers ability to successfully resolve such customer-reported failures. The initial response, failure analysis, and corrective action turnaround time requirements for customer-initiated proble
12、m analysis or corrective action requests, vary widely. This document is a compilation of the most common requirements involving problem analysis and corrective action associated with customer-reported problems and provides guidelines for the establishment of common expectations for both the Supplier
13、 and the Customer. JEDEC Standard No. 671B -ii- JEDEC Standard No. 671B Page 1 COMPONENT QUALITY PROBLEM ANALYSIS AND CORRECTIVE ACTION REQUIREMENTS (INCLUDING ADMINISTRATIVE QUALITY PROBLEMS) (From JEDEC Board Ballot JCB-12-01, formulated under the cognizance of the JC-14.1 Subcommittee on Reliabil
14、ity Test Methods for Package Devices.) 1 Scope The scope of this standard includes any customer-initiated component problem analysis/corrective action request and supplier-identified component nonconformance to specification which may impact the customer. This standard establishes a common set of cu
15、stomer and supplier expectations and requirements that will help to facilitate successful problem analysis and corrective action of component problems, including administrative quality problems, which may affect the customer. 2 Applicable documents ANS ISO9001:2000, Quality Management System (Qualit

21、ct that has led to a nonconformance. failure mode: The way in which a failure mechanism manifests itself in a failing component (electrical signature or workmanship standard). preventive action: Action taken to modify the management systems, practices, or procedures to prevent recurrence of the curr
22、ent problem and similar problems where applicable. problem analysis: Investigation to determine the root cause of a reported component problem. root cause: The source of the failure mechanism or cause of an administrative problem. 4 Requirements In conjunction with this requirements section, annex A
23、 provides a typical flowchart and annex B provides a typical tracking and report form. 4.1 General requirements - Supplier The Supplier is expected to perform failure analysis upon request, and is therefore required to maintain failure analysis expertise and equipment within the company, or have suc
24、h expertise and equipment available through subcontracted services in order to provide effective and timely analysis and conclusions. If the risk of a verified component problem is determined to be significant and may affect other customers, the supplier shall attempt to notify all potentially affec
25、ted customers of record in a timely manner of the problem and provide a status report of failure or problem, containment and corrective action. This requirement applies to both customer-identified and supplier-identified noncompliance. 4.2 Component Problem Description and Submission - Customer Prob
26、lems identified by the customer shall be communicated to the supplier in a timely period to minimize further manufacture and distribution of problem components. The customer shall segregate and control problem components to minimize or eliminate the possibility of subsequent component damage includi
27、ng damage caused by the handling and shipping / media prior to Suppliers analysis. JEDEC Standard No. 671B Page 3 4.2 Component Problem Description and Submission Customer (contd) Any component deemed by the Supplier to be in a condition that is not suitable for analysis will be place on hold, and t
28、he Customer notified. In such a case the analysis request may be rejected by the Customer. The customer verification data, testing conditions and analysis shall be shared with the supplier to the extent the information and conclusions apply to that Supplier and component. Customer shall interpret an
29、y data and / or information submitted with the defective component for the Supplier. The customers request for problem analysis and/or corrective action to the supplier shall include, but not be limited to the following: a) Priority level (Standard or Urgent) b) Date component failed in test or syst
30、em c) Sample(s) of the reported problem, in testable condition. d) Customer request/tracking number. e) Manufacturers part number. f) Supplier part number. g) Top and bottom, if applicable, part marking. h) Location of problem detection (receiving inspection, manufacturing process, life testing, fie
31、ld, system, etc.). i) Identification of the failure mode, terminal, etc. j) Operating conditions and environment (voltage, current, temperature, timing, pattern, vectors, application, etc.). k) Problem category and detailed description of the observed problem. The standard set of problem categories
32、to be used is: Electrical Visual/Mech. Administrative Functional Marking Wrong product Parametric Leads Wrong quantity Timing Package body Packing/materials Continuity Solderability Orientation Programming Contamination Date code Other Other Paperwork Shipping damage System / Application Shipping er
33、ror Labeling Other NOTE For the purpose of obtaining a cooperative and proactive analysis methodology that best suits the component and failure mode the Customer is advised to contact the Supplier prior to the initiation of any destructive physical analysis. JEDEC Standard No. 671B Page 4 4.3 Proble
34、m verification and identification - Supplier Upon receipt of the reported problem samples from the Customer, the Supplier will verify the stated problem/failure mode to the device specification or the agreed upon purchase specification, including visual, mechanical inspection and / or electrical tes
35、t, where applicable. If the Customer doesnt submit any technical information with the defective component, the Supplier can a) Reject the analysis. b) Perform their standard electrical test. c) Place the analysis on hold and contact the Customer for additional information. Verification may be done o
36、n a representative sample of each failure mode or problem observed by the Customer. It is not required that the Supplier verify every device that exhibits the same failure symptom. If the problem is verified by the Supplier, then all known elements of the problem, if any, shall be identified. This i
37、ncludes, but is not limited to, failure mode, location of the problem, effect/impact of problem, date/lot codes, etc. A clear statement of the problem and known impact shall be generated and submitted to the Customer. It should be understood that full knowledge of the problem may not be available pr
38、ior a more detailed problem analysis. If the problem is not verified by the Supplier, the Customer has the responsibility to identify all failing conditions and upon request from the Customer the Supplier is expected to assist the Customer in identifying the source of the problem. The problem may be
39、 a test or application issue, handling, customer error, design, etc. If the Customer fails to provide the requested support or information the Supplier may choose to close out the analysis request with a conclusion of “problem not verified”. 4.4 Containment strategy - Supplier/Customer As soon as po
40、ssible after verification of a component problem that may impact the Customer, a containment strategy must be defined and implemented by the Supplier. The extent of any containment actions taken should be appropriate to the magnitude of the identified problem. a) The containment strategy must includ
41、e the method and results of verifying the containment actions and the disposition of nonconforming product at the Suppliers and Customers location. b) The containment strategy shall be communicated to the Customer. JEDEC Standard No. 671B Page 5 4.5 Failure or problem analysis Supplier/Customer If f
42、urther analysis is warranted, based on customer request, the supplier shall document a failure or problem analysis plan and corresponding schedule that will be communicated to the customer and tracked to completion. a) The analysis may be done on a representative sample of each observed failure mode
43、 or problem. It is not required that the supplier analyze every device that exhibits the same failure symptom. b) Signature analysis is acceptable in lieu of performing analysis on components when failure symptoms and their corrective actions are directly related. c) Customer, upon request from the
44、Supplier, shall assist in the understanding of how the defect occurred in the customers application. d) The supplier shall generate a formal report upon completion of failure or problem analysis and provide a copy to the customer. 4.6 Corrective actions - Supplier and/or Customer When the results of
45、 problem verification, failure or problem analysis indicate a need for corrective action by the supplier, the supplier shall document a corrective action plan and schedule, which will be communicated to the customer and tracked to conclusion. When the results of problem verification, failure or prob
46、lem analysis indicate a need for corrective action by the customer, the customer shall document a corrective action plan and schedule, which will be communicated to the supplier and tracked to conclusion. The corrective action plan shall include, as a minimum: a) Investigation of root cause of the f
47、ailure mechanism or administrative problem (if not already known). b) Investigation of why the quality system did not detect and contain the problem. c) Identification of corrective actions to eliminate the root cause. d) Verification of the root cause and effectiveness of the corrective actions. e)
48、 Implementation schedule for corrective actions. 4.7 Preventive action - Supplier and/or Customer The supplier and or the customer, when the corrective action has been completed, shall modify the management systems, operating systems, practices, or procedures to prevent recurrence of this and simila
49、r problems, where applicable. The preventive actions shall be documented and communicated. JEDEC Standard No. 671B Page 6 4.8 Time frames Unless otherwise agreed to, analysis of customer-reported problems shall be completed in accordance with the time limits given in Table 1. It is recommended that the Supplier track and report actual performance in comparison to the time limits in Table 1 to understand if improvements are necessary. This metric shall be available for review during regular Supplier/Customer reviews meetings. The Supplier is required to notify the Customer in
