1. Electrical components in everyday Transport The environmental impacts that effect the cost of electrical products By David Howarth

2. Where are they used? Electrical components are found in more places than people think. They are in a range of devices from: Motor bikes Aeroplanes and Cruise Liners

3. My presentation I am going to focus on the microchips in cars, more specifically... The ones found in TOM TOM Satellite navigation systems.

4. Why are these devices so expensive? The materials used to manufacture them Plastics Silicon PCB’s Add to the cost

5. Manufacturing Issues It takes time to produce Silicon microchips. Silicon dioxide has to be refined. 7 long processes are needed to turn silicon dioxide into a finished microchip. These consist of mining silicon dioxide, silicon conversion, wafer fabrication, final cleaning, etching, layering, ion implantation.

6. Environmental Impacts As environmental issues get more and more serious the cost of producing high-complex- material-based items increases greatly. As governments introduce changes and fines for the disposing of hazardous and non- biodegradable materials, companies are researching ways to keep their own costs down which inversely effects the retail price (prices increase).
