    Hello, PCB expert,

     

    Here is my question, I have a board done, but it is 3 mils thinner than the spec. is it possible I ask the fab house to redo the soldermask and silkscreen to make it thicker? what is your suggestion if I don't want to rebuild the board.

     

    thanks,

    David,

     

    How thick was the pcb meant to be  ?

    Did the supplier agree the thickness tolerance when you ordered ? (in which case you could get the supplier to start again)

    (Generally speaking  I don't think that suppliers of prototype boards keep ultra careful control of board thickness - it's not a key issue to most users.)

    If the board is too thin can't you pad it yourself ?
