UltraFlex induction soldering copper heat pipes to PCB board in 15 seconds
This UltraFlex demonstration once again proved the time- and energy- efficiency of induction soldering.
UltraFlex - a manufacturer of advanced, digitally controlled induction heating solutions - regularly conducts tests and demonstrations to prove the efficiency of induction heating and identify the best equipment parameters for each specific induction heating scenario.
In this test case the customer - a leading manufacturer of clinical diagnostic equipment striving to drive innovation in the Magnetic Resonance Imaging (MRI) technology - required induction soldering of flat copper heat pipes to PCB board using low-temperature solder paste. The result pursued was reducing the current 1-hour manufacturing time to produce 16 soldered flat copper pipes.
An UltraFlex SM-5/200 induction heating unit along with an HS-4W heating station had been considered appropriate for this heating scenario. The induction heaters from UltraFlex UltraHeat SM series are compact 5kW induction heating systems operating with either water-cooled or air-cooled remote heat station. They feature adaptive digital phase control providing efficient operation in a wide frequency range.
To perform the test, the copper pipes were positioned onto two flat pads containing low-temperature solder paste. At power output of 1.88 kW and using a custom, cement-coated coil to ensure against mechanical damage, it took mere 15 seconds to accomplish the soldering of each copper pipe.
Thanks to the guaranteed repeatability of the induction soldering process and the possibility to simultaneously solder multiple parts, by using induction heating the customer would achieve a significant cut down in soldering time and hence, in manufacturing costs. In addition, the induction soldering would be a completely safe and green operation, with no waste heat or noxious emissions.
