When a technician solders a spade connector to a wire, what type of solder should be used?

  1. 60/40

  2. 50/50

  3. 95/5

  4. 70/30

The correct answer is: 95/5

When soldering a spade connector to a wire, it is important to use a solder with a higher percentage of tin such as 95/5. This type of solder has a higher melting point, making it more durable and less likely to melt or break under heat or pressure. Options A, B, and D have a higher percentage of lead, which makes them more malleable and easier to melt. However, this also makes them less durable and increases the risk of the connection breaking or deteriorating over time. Therefore, it is important to use the correct solder in order to ensure a strong and lasting connection.
