The fully automated assembly station VersaGlue takes components, such as lenses or dies from a loading area and mounts them by epoxy gluing with UV or thermal curing. The large work area of up to 1000 mm x 1000 mm provides space for the positioning of device trays and support systems. The parts are presented manually or fully automated. Feeders or stop-motion conveyor belts bring the parts to the working area and collect the finished product. The VersaGlue processes optoelectronic elements like VCSELs, photo diodes, laser dies and micro optics with highest precision while the passive placement of fiber ribbon cables is another major application.Thorough design and continuous optimization of all functional groups lead to superior mechanical stability. Mechanical references with tight tolerances provide a repeatable manufacturing operation from device to device.

VersaHybrid is a semi or fully automated production system for complex assemblies which require a precision in the low micrometer regime. Assembly techniques include micro welding, selective laser soldering and gluing plus laser fine cutting. Various processing methods are combined in one station. Feeders, belts and robots allow for full automation.

VersaSolder uses selective laser soldering for applications where other methods fail. A laser beam heats an area without impacting the surrounding the key advantage of this non-contact joining technique.A lens assembly focuses the laser power which melts the solder onto the working area. It is tailored exactly to the specific shape of the solder joint and the beam may be circular, elliptic or a straight line. An optional pyrometer measures the temperature in the melt pot and the electronic actively regulates the power profile. Multiple solder heads heat various areas at the same time and a symmetrical arrangement reduces shift. In order to achieve higher productivity, nanosystec developed the Multi Beam Optic (MBO). It generates a number of sub beams processing more than one connection in the same time – up to 40 individual spots have been demonstrated.

Exactly tailored to the respective process requirements of the devices, VersaWeld provides high productivity from the beginning. The application determines which laser source will be used and thus stainless steel, Kovar, Titan alloys and nonferrous metals can be efficiently processed. Typical devices for precision laser welding include sensors, micromotors, medical components and other miniature elements such as housings which require leak tightness.
