Product and process changes are necessary to improve product quality and manufacturing efficiency as well as to guarantee continuity of supply. In ST, we anticipate potential problems linked to changes and protect our customers by applying risk management principles before implementation.
In compliance with JESD46 “Customer Notification of Product/Process Changes by Semiconductor Suppliers”, we notify customers of product and process changes that may affect form, fit, function, processing, or have negative impact on the quality or reliability of a product.
ST provides its customers with a Product/Process Change Notice (PCN) a minimum of 90 days before implementing any such change. The PCN describes the product or process changes, the reasons for the change, and the projected impact of the change.
According to JEDEC rules, customers should acknowledge receipt of the PCN within 30 days and must accept or refuse the PCN. Requests for evaluation samples must also be made within 30 days of the notification.
All product and process changes are analyzed, assessed and qualified before implementation. When changes do not affect form, fit, function, processing, or do not have negative impact on the quality or reliability of a product, ST reserves the right to make changes without notification.
We provide our customers with a Product/Process Information Letter for changes that are not expected to result in any impact on form, fit, function, quality or reliability of the product.
Customer approval of the PIL is not required. However, we remain at the complete disposal of our customers for any questions or concerns about the change.
We may need to terminate the manufacturing of a component for various reasons, such as:
In compliance with the JEDEC standard JESD48, we provide a Product Termination Notice (PTN) to all impacted customers and approved agents, including distributors, allowing a minimum of six months from the notice to place final orders and 12 months from the notice for final shipments.
This notification is followed by a negotiation with our customers to provide information and technical data, validate potential alternatives and agree on the duties required to maintain the continuity of supplies.
