What is solder flux? (30 - 40 words).

Words:0

List 2 types along with application for each type.

Words:0 #12. What is a resin core? Mention its types and diameters available along with the application. (in about 30-40 words)

Words:0 #13. List 3 types and applications of soldering irons.

Words:0 #14. Fill in the blanks with appropriate words given below for the procedure of soldering electrical

connections: 1. Safely position the soldering iron while it is up. While the soldering iron is heating,

remove an appropriate amount of the protective insulation from the wires with wire strippers. 2. the

wires together to make a good mechanical connection between them. 3. Tint the soldering iron tip

and gently heat up the wires while placing the solder to the soldering iron. 4. Identify a good solder

joint and confirm solder has been drawn into the joint completely. 5. Once the electrical connection

has been made, slide insulator sleeve cover over the joint and use a to shrink the tubing around the

joint. 6. Place the heated iron onto the terminal to get it hot enough to the solder applied to the end

of the crimped wire tabs. 7. Take care not to use too much solder as the wire starts to melt if the

terminal gets too hot. 8. Once the electrical connection has been made, wait for it to cool down

without moving the solder joint. 9. Once it is cool enough, place the heat-shrink tubing over the, heat

it up with a heat gun, and place the connection into service.
