Week 5

PCB layout

  1.  The PCB layout is a mirrored positive one - black on white.
  2. Mirrored as viewed from the silkscreen top (component) side.
  3. The PCB layout is printed 1:1 on paper by means of a laser printer or copier machine.  
  4. The laser printer or copier toner will not run out when it gets wet or oily.
  5. The ink of an inkjet paper print does run out and inkjet printers are therefore useless with the described method.

 Circuit Diagram


  1. Very popular microcontroller.
  2. A lot of references and a very good supports by the manufacturer
  3. So many choices of microcontroller design with different function and application
