The shelf life of PCB is mainly divided into two aspects: inventory period and shelf life. The inventory period refers to the time period during which the PCB is considered safe to keep in inventory, while the shelf life is the time during which the PCB can be safely used.
1. Inventory period
The inventory period refers to the time period during which the PCB is stored. During the production process of PCB, a certain inventory period is required. This is because the PCB needs to be inspected and tested during the production process to ensure its quality. The inventory period will also vary at different times of PCB production.
2. Shelf life
The shelf life refers to the time period during which the PCB can be safely used. Since the PCB will be affected by the environment, current and other factors during use, the time when its failure occurs is also uncertain, so the shelf life is usually directly related to the production process, product quality and scope of use.
