Induction Soldering Fabric to a Kovar Tip Assembly

THE LAB at Ambrell tested an induction heating application involving soldering fabric to a Kovar tip assembly. An Ambrell EASYHEAT^TM 1.2 kW, 150-400 kHz induction heating system equipped with a remote workhead and three-turn pancake coil specifically designed for this application was determined to be the right solution for this soldering application. The target temperature was 300 ºF (149 ºC) and the system frequency was set to 242 kHz. 

The three-turn pancake coil was used to heat the tip of the cone to 300 ºF (149 ºC) in 2-3 seconds. The coil design allows for easy placement of the fiber across the tip of the cone and reduces the heat flow to the bottom of the assembly for the manufacturing process. The timing and quality met the client's objectives. 

Using induction for a soldering application like this one offers several benefits. Speed, precision, repeatability and safe, flameless heating are among them. Once the process is determined, you can count on getting the same result every time. It's also hands-free, which not only boosts repeatability with there being less dependence on operator skill but worker safety too. In this case, repeatability and the resulting enhanced product quality were the key factors that led to their decision to switch to induction.

This is just one example of the many applications that THE LAB at Ambrell handles on a daily basis. You can explore a full range of application notes from various industries. And, of course, we welcome you to send in your parts for free testing. Be sure to ask about our new Virtual Lab Service offering, where you can observe testing live from the comfort of your office.
