Title: 1.3 Hand vs. Automated Soldering Quiz
Course: Electronics Assembly & Soldering (Sandbox) > Section: Module 1: About Soldering

Q: In an industrial setting, the decision to solder by hand or automation is made primarily by...
- whether or not the project is through-hole or surface mount.
- how many components have polarity.
- the volume to be produced.
- the complexity of the PCB.
A: the volume to be produced.

Q: Hand soldering transfers heat primarily through...
- conduction
- convection
- radiation
- a combination
A: conduction

Q: In industry, hand soldering is usually used for repairs or...
- soldering magnetized components.
- when working on red PCBs.
- highly sensitive work that does not require high-speed production.
- soldering wires to PCBs.
A: highly sensitive work that does not require high-speed production.

Q: Solder paste is used to attach components to their contact pads, after which the circuit board is conveyed through an oven, which melts the solder. This describes _____.
- reflow soldering
- wave soldering
- robotic soldering
- hand soldering
A: reflow soldering

Q: Reflow soldering is used primarily with...
- attaching wires to circuit boards
- hand soldering
- through-hole soldering
- surface mount soldering
A: surface mount soldering

Q: The circuit board is passed over a pan of molten solder in which a pump produces an upwelling of solder, and the components are attached to the PCB. This defines _____.
- wave soldering
- vapor-phase soldering
- reflow soldering
- rebotic soldering
A: wave soldering

Q: A liquid chemical is heated to its boiling point to form steam, and the steam heats the solder paste at the bottom of the board. This is a definition of _____.
- wave soldering
- reflow soldering
- vapor-phase soldering
- robotic soldering
A: vapor-phase soldering

Q: Soldering with great efficiency and accuracy, as well as having the ability to use a variety of heating tools. This defines _____.
- reflow soldering
- wave soldering
- vapor-phase soldering
- robotic soldering
A: robotic soldering

Q: An advantage of vapor-phase soldering over reflow soldering is:
- It is less expensive.
- It heats the components more evenly.
- You can get more PCBs in a VP oven.
- It heats up faster.
A: It heats the components more evenly.
