Note: Soldering Ferrule and Module Assembly
Objective:
To heat ferrule and module assemblies for a soldering application in the fiber optics industry.
End Product:
fiber optical device
Equipment:
Ambrell EASYHEAT™ 1.2 kW, 150-400 kHz induction heating power supply with a workhead and coil specifically designed for this application
Materials:
kovar ferrule, copper housing
Temperature:
358 °F (180 °C)
Frequency:
280 kHz
Testing:
A custom-designed single position multiple-turn helical coil was built to generate the required heating for this application. A small amount of energy was used so that the client would have time to adjust the ferrule inside of the module while the solder is in a liquid state. It was observed that the first module soldered within a minute and the second module was soldered within three minutes. This achieved the objectives required from the client’s process
Benefits:
-
Repeatability: The client had been using a soldering iron and induction offers superior repeatability.
-
Speed: While speed was not of particular concern in this application, induction can offer superior speed compared to a soldering iron.
-
Part Quality: Superior repeatability means a more consistent result and enhanced product quality
