Ambrell’s outstanding expertise in induction heating applications and the innovative spirit of the dynamic company prove effective heating solutions for a huge variety of branches. This has been the case in optimization of the soldering process for one of our customers. This company turned to Ambrell with a question of doubling their production rate. Induction heating achieved that objective by 50% efficiency increase. And here is how.
The objective was to heat a Kovar ferrule and fiber optic cable to 147°C to achieve a hermetic seal. The process should have taken no more than 10 seconds. The cable was gold – coated and for the purpose of soldering, Ambrell applied a solder in order to achieve a strong, clean joint.
In order to fulfill the requirements, Ambrell applied its 1 kW EASYHEAT 0112 induction heating system equipped with a remote workhead. Our lab engineers designed and developed a four - turn ‘C’ shape coil to provide uniform heat to the assembly near the joint area. With this design, the coil could be lowered directly to the joint area and it was not necessary to feed the ferrule assembly through the coil. Flux was applied to the assembly where the ferrule and fiber optic cable were to be joined. RF power as applied for 10 seconds, which caused the solder to melt and flow. The complete assembly is presented in Picture 1.
Our customer achieved a very impressive efficiency increase rate by using Ambrell’s induction heating solution. The short process example illustrates numerous advantages of the use of induction heating in material joining applications, such as soldering. Beyond the speed of heating, the consistent heat pattern and the increased production rate, induction heating offered other benefits. Ambrell’s induction heating solutions provide instant start up time requiring little power, accuracy and versatility during the heating process and even distribution of heat. More importantly, induction heating is a clean source of energy which can be easily integrated into existing automated production systems.
