yes I have seen that same problem several years ago we didn't change anything the problem went away when we used a differant date code from the same vendor I just figured it was comtaminated leads

We'd expect that a 0603 in properly cured, in-date code, properly dispensed chip bonder would take 5-8 pounds to push off the board.

Therein lies the issue. Unknown storage conditions before we received the PCBs, date codes just expired (2 weeks), first article is de-lam city! Had a bad feeling about it. Have read some studies showing that there is no linear tie in of visual cha

From looking at your images I would say it could be poor solderability on the terminations of the component itself. Can you get your hands on a different date code and try them out?

Search on Attrition, I think most companies start around 2% across the board. I have adjusted mine higher for 0603, and parts where I experience tape issues constantly. We are running parts with date codes back 2006,2008.

It is a AVX TAR series. Commonly called a bullet cap and is now most likely obsolete. AVX 9915 is a date code or lot number. 15uM is the value, probably 15 micro farad but not sure.

If you do 100% incomming inspection the operator will not have to worry about the part being right or wrong. we do 100% at our facility and create a custom barcode label for lot code and date code traceability. that way we know if the part does not h

Are the voids in the balls of a BGA? Are you verifying this through x-ray if they are? some voids depending on size and location are some what accepted. Solder paste type? Solder paste date code? Humidity high? PCB's been stored in a truck trailer?

| Does anyone know why this typically occurs. We have seen capacitors crack due to stressing. Any good solutions? | Regards, | | Steve. Hi steve! Did you check component date-code, reflow profile and component placement height. it has happen to me

What are other testing/process step that we should do if we where to use the old date code QFPs other than solderability and baking ? What is the plating composition normally %? lead, % tin etc. I have my policy not to accept the more than 12 mont
