GROSS-UMSTADT, Germany, July 8, 2011 — The NanoRapid from nanosystec GmbH is a high-speed selective laser soldering system that is well suited for high-volume production. Its productivity reduces manufacturing costs. Selective laser soldering has numerous advantages for connecting electrical circuits and subassemblies. Concentration of the energy precisely on the solder point limits unwanted heating of the surrounding components. Because the laser beam can be focused to <0.1 mm spot diameter, electrical circuits with a very fine pitch can be easily processed. The intensity of the laser power is adjustable. Exposure duration is selectable, so the ideal temperature profile can be achieved. Laser soldering is used only sporadically for industrial applications because the soldering time per solder point is on the order of seconds. The system resolves this limitation by enabling several solder points to be processed in parallel, increasing throughput proportionally. The optical assembly generates several individual laser beams, each of which is tailored according to the requirements of the task. The geometrical form fits perfectly to the shape of the solder point, and the power distribution among the individual beams takes the specifics into account. The technology is the result of intense research and uses modern optical components and principles. Optical subassemblies generating more than 43 laser beams have been realized. The lateral distribution of the laser beams can follow any pattern. The system is designed for integration into production lines. It has all necessary interfaces and meets industrial standards. Existing lines can be easily retrofit.
