This document states the policy of Apacer Product Change Notice (PCN) & End-of-Life (EOL) criteria.

Product Change Notice Policy:

    • b. Change description
    • c. Reason for product change
    • d. Recommended Replacement/Action
    • e. Schedule includes Effective date, Last-Buy-Order date, Last-Buy-Shipment date
  • 2. In terms of flash industries nature, flash vendors have no choice to improve process efficiency in order to reach a compromise among cost, performance and reliability. Thus, in case flash chip process changes, Apacer will provide the EOL letter released by vendor along with the PCN a minimum of two (2) months before the implementation of any affected products changes.
  • 3. Based on certain conditions, in case the controller's firmware changes, Apacer will provide the PCN a minimum of three (3) months before the implementation of any affected products changes.
  • 4. Considering a hardware change may need long-term verification in customer side, so in case the product's hardware (key component or PCB) changes, Apacer will provide the PCN a minimum of six (6) months before the implementation of any affected products changes.
  • 5. During product design stage, customer may request Apacer to provide engineering sample for early design verification, but Apacer has the right to make any modification without notice to customer if the final product version has any change after mass-production.
