Particular device or packaging modifications or modifications in load configuration or density can increase the permeation situations of dampness or EtO, or the two, Therefore lowering the efficacy on the cycle. Samples from your unsuccessful ton must be as compared to samples retained from preceding lots. If changes are created, an engineering review really should be requested To guage the effect these modifications might need within the diffusion coefficient of each and every packaging layer from the load, together with shrink wrapping if utilised.
The request for information ought to be in crafting and a replica of it should be placed, combined with the supplier's reaction, during the file preserved all over the failure investigation. Even if the BI producer is unaware of any irregularities, it is feasible that anything (e.g., desiccation) greater the resistance in the BIs all through website transport or storage.
