Introduction
Long-term storage requires proper execution of storage procedures, especially the storage environment. The purpose of this document is to provide guidelines for the long-term storage of electronic components.
Guidance. This document proposes a method to delay obsolescence to the greatest extent possible, but it cannot guarantee that components will be in good condition after storage.
Work status.
GB/T 42706, "Electronic Components and Semiconductor Devices - Long-Term Storage," aims to ensure that components have sufficient energy reserves for use after long-term storage.
Reliability. Users are encouraged to request technical specifications from suppliers for relevant products to demonstrate that the storage process meets their needs. These specifications...
The aim is to provide relevant guidance for electronic components that require long-term storage.
GB/T 42706 is divided into 9 parts. Parts 1 through 4 apply to all long-term storage and include general requirements and specifications.
Guidelines. Parts 5 through 9 apply to the storage of several specific product types. This is in accordance with the general requirements of Parts 1 through 4.
At the same time, the requirements for specific product types must also be met.
Starting from Part 5, we will cover electronic components that require different storage conditions.
GB/T 42706 is proposed to consist of nine parts.
---Part 1.General Provisions. The purpose is to define the relevant terms, definitions, and principles for long-term storage, and to provide effective methods for long-term storage of electronic components.
Storage concepts, good work habits, and general methods.
---Part 2.Degradation Mechanisms. The aim is to define the degradation mechanisms of electronic components over time under actual storage conditions and...
Degradation patterns and guidelines for testing methods to assess general degradation mechanisms.
---Part 3.Data. The purpose is to specify the requirements for data storage during the long-term storage of electronic components, ensuring traceability.
Traceability or data chain integrity.
---Part 4.Storage. This section describes methods for long-term storage of electronic components and related recommended conditions, including transportation and control.
Safety of manufacturing and storage facilities.
---Part 5.Chips and Wafers. The purpose is to specify individual chips, portions of wafers, or entire wafers, as well as those with metal structures (introduced).
Storage conditions and rules for chips (metal layers, ball bearings, pillar bearings, etc.), and also for general-purpose and special-purpose packaging products containing chips or wafers.
Provide operating instructions.
---Part 6.Packaged or Coated Components. The purpose is to specify the methods and recommended conditions for long-term storage of packaged or coated components.
This includes the safety of transportation, control, and storage facilities.
---Part 7.Microelectromechanical Devices. The purpose is to specify the precautions and basic requirements for long-term storage of microelectromechanical devices.
This requirement.
---Part 8.Passive Electronic Devices. The purpose is to specify the precautions and basic requirements for long-term storage of passive electronic devices.
This requirement.
---Part 9.Special Cases. This section aims to specify storage methods for special types of products and when the storage environment changes, providing users with [specific guidelines/methods].
Guidelines and requirements for interacting with suppliers help manage the complexities involved.
Long-term storage of electronic components and semiconductor devices
Part 8.Passive Electronic Devices
1 Scope
This document applies to passive electronic devices intended for long-term storage and can be used as part of a strategy to delay obsolescence. Long-term storage refers to products expected to be stored long-term.
Storage periods exceeding 12 months. Typically, the original supplier affixes the packaging date or date code to the product before storage begins. Distribution.
Both suppliers and customers have a responsibility to control and manage inventory after receiving products marked with a date, or to establish a supplier-customer agreement to manage inventory.
This document provides principles, best practices, and general methods for the effective long-term storage of passive electronic devices.
