A further explaination to SteveSmith's answer is that 1oz copper is measured as .0014 thickness as the 1oz copper is evenly spread over a 1 square foot area. As you would guess, 1/2 oz = .0007, 2oz = .0028, etc. are simply multiples of that value. Take care...
Please provide any comments on determining the appropriate support or fastening distances required for a pcb to meet a certain weight of pcb, thickness, orientation, and vibration level that the pcb will be exposed.
