Hello TechNet,

I have an IC Op Amp that was found in stock with the lid separated. The stock room discovered this while kitting components, so this part was minimally handled. It was stored in the original IC tube. Collectively, we have never seen an occurrence of something like this, and I wonder if any of you have experienced this before. The explanation I got from the manufacturer is that it is most likely a packing and/or handling problem and that if there is too much slack in the tubes, the parts colliding together could cause the lid to pop off. Wouldn't the seal material be more robust than to allow the lid to pop off? My concern is that we have 120 of these all from one lot, and if there was a processing problem, then maybe I have some other poorly bonded lids that may separate. Do you think my concern is valid, or is this a one-off rare handling caused defect? These are space grade parts.

Thanks to Steve, a couple pictures are posted on the links below. I don't know what could be determined from the first picture, other than yes, the lid definitely popped off! The second picture shows another IC with a lid slightly skewed, but within tolerance I believe. Thanks in advance for any suggestions you can offer.
