First, I am aware this has been discontinued.
My question is in regards to the package - is the package cover hermetically sealed (soldered or glued?) to the body, or just securely fastened (snapped?) in place?
The lid is hermetically sealed with solder.
Thanks for clarifying this.
Follow-up question: is the solder seam which secures the cover to the ceramic very thin, or is it more robust and able to be detected under a microscope?
OK thanks - can you ask elsewhere within the product line? Should I create a new post?
I am sorry if I am misunderstanding, but the motive for the question is not clear and it seems to be asking for a very fine level of detail, in fairly open manner. When we factor in the age of this product and the normal turnover that any support team will have in this time frame, I suspect that it will be hard to find someone who can answer this, "off the top of their head." So, I suspect that this might take some digging and perhaps even a cross section to measure the thickness of the solder. Can you help us understand why this is important before we ask someone to invest time in this research? From a high level, we know that the package supports hermeticity. What does "robust" mean in this case? Thank you for the discussion and for supporting use of these products!
Sorry for not initially providing more detail.
My customer has several failed units of this part. On some of these, they believe the cover solder seam has voids which could cause the cover to separate from the ceramic. The customer is asking this to find out if they can investigate the integrity of the solder seam themselves. If a better course of action is to return the parts to ADI for failure analysis, please advise. Thanks.
I am sorry to hear about that. If your customer is willing to provide some representative samples and a clear description of the process and observations, which lead them to this conclusion (failure in the lid seal), I believe that the Failure Analysis process will provide more depth and value than we can provide in this forum. Thank you for providing them with this service! We really appreciate it!
