JEDEC/ECIA/IPC Joint Standard No. 46 Page 1 CUSTOMER NOTIFICATION STANDARD FOR PRODUCT/PROCESS CHANGES BY ELECTRONIC PRODUCT SUPPLIERS (From Board Ballot JCB-16-40, formulated under the cognizance of a joint industry working group with the JC-14.4 Committee on Qualit
12、y Processes and Methods, ECIA, and IPC.) 1 Scope This standard is applicable to suppliers of, and affected customers for, electronic products and their constituent components. This standard establishes the requirements for timely customer notification of changes to electronic products and associated
13、 processes. 2 Terms and definitions approved supplier agent: A direct sales channel, an authorized manufacturers representative, or an authorized distributor. authorized distributor: A distributor that has an ongoing, contractual relationship with the supplier and a written agreement to sell the sup
14、pliers product. change, (product or process): An alteration to the product or process, which may be a major change or a minor change. NOTE 1 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 mi
15、nor change is a change that does not affect the form, fit, function, quality, or reliability of the product. component: A constituent part. customer: Any organization that: 1) has purchased the product from the supplier within the past two (2) years and has a contract or purchase agreement with Proc
16、ess Change Notice (PCN) requirements, or 2) has requested (and the supplier has agreed to provide) PCN information, or 3) is an approved supplier agent and has purchased the product within the past two years. JEDEC/ECIA/IPC Joint Standard No. 46 Page 2 2 Terms and definitions (contd) electronic devi
17、ce: A device whose operation depends on the conduction of electrons in a vacuum, gas, or semiconductor. NOTE Examples of electronic devices include transistors, integrated circuits, hybrids, and modules. electronic product: An item containing one or more electronic devices performing major functions
18、. fit: The external dimensions 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, t
19、hermal, and performance 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.

20、rocess 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. Proposed First Ship Date: The date that the changed product could first be shipped to customers. quality: Conformance of a product to re
21、quirements, 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. supplier: Any organization that: 1) is the original product manufacturer and is thus responsible for generating
22、 the Product/Process Change Notice, or 2) is an approved supplier agent. NOTE Any organization that receives a Product/Process Change Notice for a product that is a component within their own product is not considered to be a supplier for purposes of this document and is not required to forward the
23、Product/Process Change Notice on to its customers; however, depending on how its product is affected, said organization must determine whether it needs to generate its own Product/Process Change Notice for its own customers. JEDEC/ECIA/IPC Joint Standard No. 46 Page 3 3 Requirements 3.1 Documentatio
24、n The supplier shall have a documented PCN process that includes the criteria or methodology used to classify the changes as major or minor (See Annex A for examples of commonly accepted types of changes). The following minimum elements must be included in the suppliers documented PCN procedure: a)
25、Method of identifying and documenting the customers unique PCN requirements. b) Definition and classification 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 c
26、hange notification. e) Record retention requirements. 3.2 Procedure 3.2.1 Classify changes(s) The proposed change should be classified as either major or minor. A major change is any change that may affect the form, fit, or function of the product or adversely affect the quality or reliability of th
27、e product. Each supplier shall include in their internal PCN specifications a list of what constitutes a major change (See Annex A for examples of commonly accepted types of changes). The notification document for a major change must clearly state that it is a PCN (Product/Process Change Notificatio
28、n). Customers must be notified of major changes, whereas notification of minor changes may or may not occur depending on supplier and customer/authorized distributor written agreed requirements. Minor change notifications may also be referred to as an “Informational Notice”, “Supplier Communication”
29、, or similar title. If such a notice is sent out, it must clearly state its purpose, so as not to be confused with a PCN for a major change. NOTE This standard proposes no specific requirements regarding documentation (see 3.1) for minor changes. JEDEC/ECIA/IPC Joint Standard No. 46 Page 4 3.2.2 Cus
30、tomer notification a) Identify affected customers b) Determine notification requirements (for review or awareness only) per special customer criteria or, supplier-agreed-to customer profile. If a customer expresses no unique notification attributes, the suppliers standard PCN system shall apply. c)
31、Customer will be notified a minimum of 90 days before the proposed first ship date of the product identified in the PCN. Shipment of changed product may occur prior to stated ship date only with customer approval. Included in the 90 day review period is the time necessary for an authorized distribut
32、or to forward the notice to its customers of the affected product. d) It is suggested that suppliers also post their generic PCN notices (i.e., notice does not contain any confidential or customer specific information) on a website to allow for potentially missed customers to view current and past P
33、CNs. 3.2.3 Customer response 3.2.3.1 Customer acknowledgement response a) Customers should acknowledge receipt of the PCN within 30 days of delivery of the PCN. Any concerns, sample order response, or a request for further information should be provided within the acknowledgement period. If addition
34、al time is required to determine if samples or additional data is required, the customer must submit this request along with the acknowledgement response and state when they expect to complete their review. b) Lack of acknowledgement of the PCN within 30 days constitutes acceptance of the change. 3.
35、2.3.2 Customer actions after acknowledgement a) After acknowledgement, lack of additional response within the 90 day period constitutes acceptance of the change. b) If the customer requires additional time to perform sample testing, beyond the 90 day review period, an extension must be negotiated wi
36、th the supplier. 3.2.4 Supplier follow-up response a) After receipt of all requested 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
37、 days constitutes acceptance of the change. b) The supplier shall notify all affected customers if a PCN is cancelled. JEDEC/ECIA/IPC Joint Standard No. 46 Page 5 3.2.5 Shipment of Changed Product Changed product may not be shipped prior to the Proposed First Ship Date without written approval of th
38、e customer. 3.3 Product and Process Change Notification minimum content The following is the 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 typ
39、es, product family) c) Customer part number(s) (optional, if not required per agreed to customer 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, quali
40、ty or reliability h) Proposed First Ship Date for change i) Supplier Qualification plan schedule 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 manufactu
41、re of the unchanged product m) Supplier contact information, such as but not limited to: name, address, telephone, and email of supplier contact n) Statement, if applicable, that device material declaration will be updated due to material change NOTE It is still the customers responsibility to reque
42、st updated material declaration when available. 3.4 Records Each supplier shall retain documentation of individual PCN information for a minimum of ten years after final user notification. JEDEC/ECIA/IPC Joint Standard No. 46 Page 6 Annex A (informative) Examples of major changes that may require cu
43、stomer notification The requirements stated in clause 3.2.1 of this document are that each supplier is to generate a documented list of which changes they consider to be classified as “major” and for which they must notify their customers. Per 3.2.1, a major change is any change that may affect the
44、form, fit, or function of the product or adversely affect the quality or reliability of the product. A customer has the right to review the suppliers list and then work with the supplier to agree upon any additions to that list. This annex has been generated to assist both customers and suppliers in
45、 providing a list of generic types of major changes that may require customer notification. Generic types of major changes (that may affect form, fit, or function or adversely affect quality or reliability) Design Change in external dimension Change of critical material/component Changes in process
46、technology affecting critical process steps Change of product marking technology Manufacturing/Test Location Site transfer to a site not previously qualified (fabrication, assembly, or test site of the finished product) Packing/Shipping Change in carrier type (tube, reel, tray, etc.) or dimensions C
