The two functions of a solder connection are - ANSWER Mechanical and electrical
connection
An imperfect solder joint may result in - ANSWER Electrical failure
Keeping your workstation clean means you can - ANSWER Avoid contamination of the
assembly
ESD damage can be controlled by - ANSWER Proper grounding
The primary reason not to eat or drink at your workstation is to avoid -
ANSWER Ingesting lead
A pointed soldering iron tip should be used - ANSWER For small connections
When a solder joint is heated for more than 3 seconds - ANSWER There may be heat
damage to the base material and plated barrel
The main advantages of 63/37 eutectic solder are - ANSWER It melts at lower
temperature and solidifies faster
1
, It's important to remove certain types of fluxes after hand soldering because -
ANSWER Sticky residues can hold electrically conductive contaminants and cause
metal corrosion
Solder wetting is defined as - ANSWER A smooth, unbroken film of solder, feathered
onto base metals
The reason it is important to use the correct solder wire diameter is - ANSWER For
control of speed and amount of solder
The reason for tinning the soldering iron tip is to - ANSWER Transfer heat rapidly
When the soldering iron contacts the cleaning sponge for too long - ANSWER The tip
may cool down too much and may affect the formation of a proper solder joint
Using excessive pressure when soldering can cause - ANSWER All of the above
We solder on the termination side of the board - away from the components -
ANSWER To prevent heat damage to the components
Preheating - ANSWER Speeds up the soldering process to help prevent heat damage to
the assembly
It's important to remove the flux residue right after the soldering operation because -
ANSWER It can harden and become difficult to remove
If you think components may be sensitive to cleaning fluids, you should - ANSWER Ask
about your company specific policy if you have any questions
