We are having issues with the ADS8684 A2D chip. Had a design built that was based off the Datasheet, including the decoupling capacitors. when we prototyped it up seemed to work fine moved on. When we sent boards out to a pick and place company we had an unusually high fail rate (6/8 failed) when I removed the chip and soldered in (by hand) I still ended up with (3/6 failed). After we got all boards working, they ran for a day and a half and then we had two chips fail. Now I understand it would seem that it is a design flaw in our boards, however this issue is very random and dosent keep happening to the same boards. Im wondering if this chip is sensitive in some way that we are unaware of... We thought it was the bake temp but it never reached a temp that was excessive. Thanks for any help!
