    You did not post a schematic.
    You did not post the board layout that you used.
    You did not post any photos of the faulty boards.
    You did not post a complete Bill of Materials list.
    My divining rod does not reach from where I am to where you are.

    You will need to supply some more information if you wish to obtain a useful reply.
