1. The two functions of a solder connection are Mechanical and
electrical connec-
tion
2. An imperfect solder joint may result in Electrical failure
3. Keeping your workstation clean means you can Avoid contamina-
tion of the assem-
bly
4. ESD damage can be controlled by Proper grounding
5. The primary reason not to eat or drink at your work- Ingesting lead
station is to avoid
6. A pointed soldering iron tip should be used For small connec-
tions
7. When a solder joint is heated for more than 3 seconds There may be heat
damage to the
base material and
plated barrel
8. The main advantages of 63/37 eutectic solder are It melts at lower
temperature and
solidifies faster
9. It's important to remove certain types of fluxes after Sticky residues
hand soldering because can hold elec-
trically conductive
contaminants and
cause metal corro-
sion
10. Solder wetting is defined as A smooth, unbro-
ken film of sol-
der, feathered onto
base metals

The reason it is important to use the correct solder For control of
wire diameter is speed and amount
of solder
12. The reason for tinning the soldering iron tip is to Transfer heat
rapidly
13. When the soldering iron contacts the cleaning sponge The tip may cool
for too long down too much
and may affect
the formation of a
proper solder joint
14. Using excessive pressure when soldering can cause All of the above
15. We solder on the termination side of the board - away To prevent heat
from the components damage to the
components
16. Preheating Speeds up the sol-
dering process to
help prevent heat
damage to the as-
sembly
17. It's important to remove the flux residue right after the It can harden and
soldering operation because become difficult to
remove
18. If you think components may be sensitive to cleaning Ask about your
fluids, you should company specific
policy if you have
any questions
19. An ideal solder joint has A concave fil-
let, complete sol-
der coverage,
smooth texture,
wetting that feath-
ers smoothly onto
