As challenges and complexities associated with manual soldering processes increase, the installation and utilization of robotic soldering stations continue to grow. These challenges include the miniaturization of electronic assemblies, the increasing density of these assemblies, and the demand for ever-improving cycle times. Robotic soldering machines, when paired with a properly optimized, high-powered, and highly effective robotic soldering wire, can alleviate the headaches of electronics assembly engineers everywhere with their consistency and repeatability. Not only do robotic soldering machines provide peace of mind during assembly, but they also enhance the efficiency and cost-effectiveness of the entire production line by reliably applying the correct amount of solder to the joint area with each application, all while reducing cycle time to allow for more completed assemblies in less time.
The machine is only one half of this assembly team; the other half is the soldering material used to create the joint, typically flux-cored wire or solder paste. It’s not uncommon for some cored wires to initially exhibit what may be deemed “defective” qualities, such as high spattering, flux charring, voids, and poor winding or tension retention. With the right adjustments to the soldering program or feeding mechanism, most of these problems can be resolved. Wire voiding and winding quality directly reflects the quality of the wire produced by the manufacturer. Indium Corporation offers a variety of fast, powerful, and reliable cored wire products that are void-free and perfectly wound—ideal for robotic soldering applications.
I foresee the adoption and evolution of robotic soldering gaining more momentum as the previously mentioned challenges become more prevalent and the need for cost-effectiveness becomes increasingly essential for electronics assemblers. This evolution could be driven by the use of AI or machine learning, enabling programs to detect defects and adjust future solder joints to achieve acceptable soldering results. Additionally, innovations in the wire or paste products used to create the joints will be necessary in tandem with robotic soldering machines. This could involve optimizing soldering speed rates and spatter control within the flux or utilizing a new alloy that spreads well while avoiding soldering iron tip degradation. The possibilities are endless!
In conclusion, robotic soldering will play a pivotal role in the future of electronics assembly. The equipment and soldering materials must adapt to keep pace with the changing demands of the industry.
