What is the definition of an IPC J-STD-001, CLASS 3 product? - ANSWER a class 3
product requires performance-on-demand, the end-ur environment may be uncommonly
harsh and the equipment must function when required
What is the proper preparation and safe maintenance of the soldering iron? -
ANSWER - the soldering iron should be checked to ensure the tip is fully inserted and
there's is no damage
- sotter should be applied to the tip when the iron's hot (must use to prevent tip oxidation)
- ensure iron tip is the correct size for connection to be soldered
- check and verify that the ESD protection date on the power supply and iron has not
expired.
-no eating/drinking/smoking at work bench
Types of maintenance required at work station: - ANSWER 1. Work surfaces
uncluttered and free of object debris (POD) = lead clipping, contamination, solder balls, etc.
2. Well organized stations that reduce risk of exposing hardware to FOB
3. Tool inserts/shadow boxing immediately alert operator when tools are missing
1
, 4. Report missing tools immediately
5. Check labels on solder + (??)
6. Report missing or expired labels immediately
7. Verify tools on benches, monitors, and tonizers(??)
The most important characteristic of an acceptable solder connection - ANSWER -
good welding
What is the heat bridge technique used during the hand soldering process? -
ANSWER - when solder is applied to the junction of the iron tip and the area to ben
soldered
- this allows proper heat to transfer to the connection
What is the purpose of flux? - ANSWER It's used to remove the oxide film from the
surface of metals and keep it removed during soldering
- flux contained within the solder core melts at a temp stirs lower than solder
- flux promotes heat transfer and reduces surface tension
Why are the wires tinned before use? - ANSWER - they are tinned to prevent bird-
caging, reduce oxidation, make lead forming easier
- also so we can bend wire tip without bird-caging it
