1、 JEDEC STANDARD Customer Notification of Product/Process Changes by Solid-State Suppliers JESD46D (Revision of JESD46C, October 2006) DECEMBER 2011 JEDEC SOLID STATE TECHNOLOGY ASSOCIATION NOTICE JEDEC standards and publications contain material that has been prepared, reviewed, and approved through
2、 the JEDEC Board of Directors level and subsequently reviewed and approved by the JEDEC legal counsel. JEDEC standards and publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvemen
3、t of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for use by those other than JEDEC members, whether the standard is to be used either domestically or internationally. JEDEC standards and publications are adopted without regard to whether or
4、not their adoption may involve patents or articles, materials, or processes. By such action JEDEC does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the JEDEC standards or publications. The information included in JEDEC standards and pub
5、lications represents a sound approach to product specification and application, principally from the solid state device manufacturer viewpoint. Within the JEDEC organization there are procedures whereby a JEDEC standard or publication may be further processed and ultimately become an ANSI standard.
6、No claims to be in conformance with this standard may be made unless all requirements stated in the standard are met. Inquiries, comments, and suggestions relative to the content of this JEDEC standard or publication should be addressed to JEDEC at the address below, or refer to www.jedec.org under

JEDEC Standard No. 46D Page 1 CUSTOMER NOTIFICATION OF PRODUCT/PROCESS CHANGES BY SOLID-STATE SUPPLIERS (From Board Ballot JCB-00-42, JCB-06-39 and JCB-11-88, formulated under the cognizance of JC-14.4 Committee on Quality Processes and Methods). 1 Scope This document covers solid-state product
11、s and their associated processes. This standard establishes procedures to notify customers of changes to solid-state products and associated processes. 2 Terms and definitions change, (product or process): An alteration to the product or process, which may be a major change or a minor change. NOTE 1
12、 A major change is a change that may affect the form, fit, or function of the product or adversely affect the quality or reliability of the product. NOTE 2 A minor change is a change that does not affect the form, fit, function, quality or reliability of the product. customer: Any organization that
13、1) has purchased the product from the supplier within the past two (2) years and has a contract or purchase agreement with Process Change Notice (PCN) requirements, or 2) has requested (and the supplier has agreed to provide) PCN information, or 3) is an approved supplier agent. fit: The external di
14、mensions and associated tolerances of the product, as specified by the supplier and/or customer. form: The visual appearance including shape, color, marking, and surface finish of the product, as specified by the supplier and/or customer. function: The electrical, mechanical, thermal, and performanc
15、e characteristics of the product, as specified by the supplier and/or customer. process: A combination of people, procedures, methods, machines, materials, measurement equipment, and/or environment for specific work activities to produce a given product or service. JEDEC Standard No. 46D Page 2 2 Te
16、rms and definitions (contd) Product or Process Change Notice (PCN): A document sent to customers describing product or process changes, the reasons for the change, and the projected impact of the change.

17、 quality: Conformance of a product to requirements, or perceived fitness for its intended use(s). reliability: The ability of a product to perform a required function at or below a stated failure rate for a given period of time. 3 Requirements 3.1 Documentation The supplier shall have a documented P
18、CN process that includes the criteria or methodology used to classify the changes as major or minor. The following minimum elements must be included in the suppliers documented PCN procedure: a) Method of identifying and documenting the customers unique PCN requirements. b) Definition and classifica
19、tion of proposed changes. (Note: This could be a reference to a separate controlled document, e.g., Engineering Change Notice.) c) Notification timing. d) Deliverables to customer - contents of change notification. e) Record retention requirements. 3.2 Procedure 3.2.1 Classify changes(s) The propose
20、d change should be classified as either major or minor. Each supplier shall include in their internal PCN specifications a list of what constitutes a major change (See Annex A for examples).

24、y missed customers to view current and past PCNs. 3.2.3 Customer response a) Customers should acknowledge receipt of the PCN within 30 days of delivery of the PCN. b) Lack of acknowledgement of the PCN within 30 days constitutes acceptance of the change. c) After acknowledgement, lack of additional
25、response within the 90 day period constitutes acceptance of the change. An acceptance, concern, or sample order response or a request for further information and respective documents response should be submitted to the supplier in a timely fashion, (i.e., customer should not wait to the end of the 9
26、0 day review period before responding, if the response is known before that time.) d) If the customer requires additional time to perform sample testing, beyond the 90 day review period, an extension must be negotiated with the supplier. 3.2.4 Supplier follow-up response a) After receipt of all requ
27、ested qualification reports, additional data to clarify the PCN, and/or samples, the customer shall have at least 30 days to review this qualification data and test samples. Lack of response by the customer after these 30 days constitutes acceptance of the change. b) The supplier shall notify all af
28、fected customers if a PCN is cancelled. 3.2.5 Shipment of Changed Product Changed product may not be shipped prior to the Proposed First Ship Date without written approval of the customer. JEDEC Standard No. 46D Page 4 3.3 Product and Process Change Notification minimum content The following is the
29、minimum content of the Product and Process Change Notification: a) PCN tracking number b) Product Identification (e.g., affected supplier part number(s), affected product lines including specific package types, product family). c) Customer part number(s) (optional, if not required per agreed to cust
30、omer criteria) d) Detailed description of change(s). e) Method, if applicable, of identifying changed product f) Reason for change(s) g) Anticipated (positive and negative) impact on form, fit, function, quality or reliability. h) Proposed First Ship Date for change i) Supplier Qualification plan sc
31、hedule and/or results, where applicable j) Date, if required, when qualification samples are available. k) Date, if required, when final qualification data are available. l) Last date, if applicable, of manufacture of the unchanged product. m) Name, address, telephone, email, and fax number of suppl
32、ier contact n) Statement, if applicable, that device material declaration will be updated due to material change. NOTE It is still the customers responsibility to request updated material declaration when available. 3.4 Records Each supplier shall retain documentation of individual PCN information f
33、or a minimum of five years after final user notification.
