Lesson 5 Soldering Iron Tips
1. The three most popular types of tip are the chisel, ___________-
__________, and ________________________.
2. Most tip cores are made from __________________, a soft highly-
conductive metal with excellent heat-storage and transfer characteristics.
3. The entire core is usually protected by an electroplated layer of
_______________.
4. If electroplate layers are worn or scraped away to expose the core, it will:
(A.) overheat, (B.) erode quickly, (C.) no longer tin, (D.) smell really
bad. [ ]
5. Why electroplate the back portion of a tip with nickel? (A.) adds ballast,
(B.) prevents wetting, (C.) provides insulation, (D.) prevents corrosion. [
]
6. Why electroplate a portion of the outer surface with chrome? (A.) adds
ballast, (B.) prevents wetting, (C.) provides insulation, (D.) prevents
corrosion. [ ]
7. If you want to solder temperature-sensitive sub-miniature components, it's
best to use a (short/long) ______________ tip with a
(wide/narrow) _________________ blade.
8. If you want to solder a fat lead to a large land-area on a pc board, it's best to
use a (short/long) ______________ tip with a
(wide/narrow) _________________ blade.
9. For a slower rate of energy transfer, use a (long/short)______________ and
(skinny/wide) ___________________ tip.
10. For a faster rate of energy transfer, use a (long/short)____________ and
(skinny/wide) _______________ tip.
