Abstract
Printed circuit boards (PCBs), subassemblies, and final assembled products are often stored for long-term. While significant work has been performed and various standards are available for the storage of electronic components, the scope of covering the storage of hardware beyond the component level remains a matter of individual company decision-making. As a result, organizations are often limited by personal experiences, and companies continue to repeat the same mistakes across the industry.
For successful, cost-effective storage of printed circuit board assemblies, there is a need for information collection and management to support storage planning and execution. This webinar will present the information required to plan for the long-term storage of assemblies. The information combines the design data package, traceability information, and future requirements expected from the stored product. The information can be used to determine storage logistics, storage conditions, handling requirements, physical and electrical testing procedures (before and after storage), and the possible storage duration. Some practices are standard for all storage activities, while others must be tailored to the specific board, its functionality, and its application.
The goal of storage planning using this information is to avoid duplicating tasks and to utilize the test, inspection, and record techniques already in place. The information will be used to identify each item in storage individually and to track its full life-cycle history from the beginning of storage. Not all information is necessary at the beginning of decision-making. However, to reduce the resources and time required to form a storage plan, when long-term storage is possible, information should be compiled and saved.
