• Soldering iron

• solder

• wick

• the board

which soldering tool is shown in the picture?

• soldering iron stand

Which soldering step is shown in the picture?

• Clean your PCB using PCB eraser

• Clean the soldering tip with a wet sponge to remove dirt and oxide

• Place the component to be soldered in position on the board. Verify that the component is positioned correctly before soldering.

• Move soldering iron until tip is touching wire

What are some advantages to using brass wool to clean your soldering iron? (Select all that apply)

What are some advantages to using a sponge to clean your soldering iron? (Select all that apply)

• Remove debris easier

• Less Abrasive

• Cheaper

If the surface area of a solder tip is increased, how will that change the heat transfer?

• More surface area will mean more heat is transferred in a shorter time

• More surface area will mean less heat is transferred in a shorter time

• More surface are doesn't change how heat is transferred

• The solder tip's surface area is always the same
