We had a similar issue with ESD causing circuit board failures causing product reliability issues. Had to perform a detailed process man and the use of a fish bone diagram to understand where exactly the ESD was introduced.
Few factors to consider were the humidity levels within the working environment and the handling of part itself within various stages in production. We had introduced anti static ESD air ionizers with a combination of Anti Static PVC Strip Curtains at the respective sections within the process to mitigate this and the use of nitrile gloves & emphasising more of a clean room environment.
