    Self-Test 2

    1. Safety factors such as toxic fumes and splashing flux should always be addressed when soldering.
      1. True
      2. False
    2. Which of the following best describes the process of surface penetration?
      1. Bonding
      2. Wetting
      3. Soldering
      4. Prepping
    3. Which of the following should apply when tinning stranded wire?
      1. The strands should be thickly coated.
      2. The strands should be visible under the solder.
      3. The solder should wick up underneath the insulation.
      4. A large blob of solder should form at the end of the wire.
    4. Metals like aluminum and iron wet easily.
      1. True
      2. False
    5. What is the purpose of flux?
      1. To remove oxides
      2. To clean the metal
      3. To assist with heating
      4. To remove the solder
    6. What is the most common alloy used for solder?
      1. Tin-lead
      2. Lead-silver
      3. Tin-copper
      4. Lead-copper

      4. Dress it with a fine file.
    4. What is the purpose of a heatsink?
      1. To protect the solder
      2. To pull flux to the joint
      3. To pull heat to the area for soldering
      4. To pull heat away from certain components
    5. What would cause a solder joint to be piled up and lumpy in appearance?
      1. Insufficient heat
      2. Lack of flux
      3. Poor tinning
      4. A corroded tip
