The objective of this soldering application test is to successfully solder a litz wire into an aluminum lug in under 30 seconds.
Ultraflex custom coil
Power: 1.75 kW
Temperature: Approximately 250°C (482°F)
Time: 25 seconds
In order to start the induction soldering process, the aluminum lug was placed in the center of the coil. Then the litz wire was placed into the lug along with the solder. The solder started to melt after 25 seconds at approximately 250°C (482°F). After the solder was completely melted it was left to cool for one minute before proceeding.
The tests were a success. We were able to prove that induction was a much faster method of soldering a litz wire onto an aluminum lug rather than using a torch as the customer had done in the past. The application testing showed an increase in productivity and control over the time and temperature.
