Merit M2

• Compare the advantages and disadvantages of PCB
  and Prototype board for building a circuit.
• Explain the different features characteristics
  which make one good for permanent finished
  products and the other good for experimental
  testing work. An advantage for one application
  can easily be a disadvantage for the other.
