Upon shipment of the product, which is in tape and reel packaging, there is a cushion material placed inside the shipment boxes (below/upper portion). This cushion material is a bubble sheet. The surface resistance of the material may sometimes exceed (marginal) the limit <1E11 Ohms but the static generation of the material is very low <10V.
This is only a one-time use, but this can reach to the customer.
Can we qualify this cushion material as an essential insulator instead as part of the packaging. Let us hear your thought on this. Thank you.
The tape and reel system should be the primary packaging for devices. If the carrier tape is qualified then it does not matter what the secondary packaging is. The primary package, the tape and reel, is ment to keep the ESD devices from damage in an uncontrolled enviroment.
In addition, the secondary packaging material is placed and removed without the devices making any additional contact with a grounded object.
In other words, the secondary packaging does not need to be qualifed.
Hi John.
What about there is the one reel (as primary) packed into black surface box separately, and at box we can see label with ESDS warning? I met the customer who said: “if you see the warning mark, you are obligated to stop unpackaging and consider the reel as ESDS itself”.
What is your opinion at that point of view?
When I addressed this with my suppliers, I always use the carrier tape as the primary packaging. The device gets pulled from the reel, the cover tape is removed and then the part is removed. With this process, the carrier tape is the primary package and the reel is secondary. I never required the reel to have any dissipitavie or conductive properties.
