Hello,
One of our customers have comeback after 3 years asking for a failure analysis report on a 10 layer industrial grade PCB. The PCB was supplied 3 years back and has been functioning satisfactorilly for the last 3 years. Now the customer has 3 PCBs which have failed and is insisting it is a PCB related failure. The failure in all the 3 circuit boards are in the same area around a quadpack IC. We verified the traveller card of the boards processed and found all aspects to be compliant. The PCBs were being used in a jig for high reliability harness checking. We feel it should be a component related issue rather than a PCB related issue.
Can you give us some inputs on the above which will help us in arriving at the right conclusion.
Rgds
