PCB manufacture
  1. Photo-etch method
    1. 1. draw the circuit on to a mask
      1. 2. The mask is then placed on the board, which has a thin coating of copper, and the circuit diagram transferred onto the board using an etch-resist.
        1. alternatively, a photosensitive board is covered by the mask and then exposed to light.
        2. 3. The circuit is then etched onto the board using ferric chloride in an etching tank.
          1. 4. Next, a small PCB drill is used to drill out the centre of the pads
            1. 5. the components are pushed through the board and soldered in place.
