Webb5 maj 2024 · Copper applied to PCB is not measured in millimeters or inches by definition. As it is added to the base in the liquid form and distributed over a PCB’s surfaces, it is measured in ounces (oz). For your consideration, 1 oz equals 0.00137 in., 1.37 mils, 0.0347 mm., or 34.79 micrometers (µm). WebbA typical visual PCB inspection checklist might include the following: Ensure that the board’s thickness is correct, and check for surface roughness and warpage. Check the dimensions of the assembly match the specification, and pay particular attention to dimensions related to electric connectors.
