According to initial estimates, in Germany about three million LCD monitors will be recycled in the year 2016. However, they often still have backlighting containing mercury and therefore have to be classified as “hazardous waste” in accordance with the German General Administrative Regulation (AVV) and registered in compliance with the German Electrical and Electronic Equipment Act (Elektro G) under category 3. Whereby special conditions must ensure that no risk arises from the mercury for the environment or for humans. However, because of a lack of suitable automated procedures for the recycling of LCD monitors, it was to date only possible to dissemble the appliances laboriously by hand, with the ensuing health dangers for the workers. For this, ERDWICH now offers two alternatives which are both safe and time-saving for recycling LCD monitors. Mercury and valuable resources can be removed and recycled in an environmentally sound way in the future: 1. Monitor sawing plant for...

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.

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.

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.

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.

The laser processing station VersaCut precisely ablates and cuts a large variety of materials, such as metals (stainless steel, nonferrous metals), ceramics like Si or AlN, and all kind of plastics. Depending on the indented use, the station uses different laser sources with the corresponding focusing optics. The modular VersaCut finds it application in research and production.A solid-state laser delivering short pulses in the nanosecond regime is ideal for cutting stainless steel, Kovar, brass and similar metals. The high peak power with a small focus on the target generates the necessary power density for clean and sharp cuts. There is however an impact on the surrounding area as some local heating occurs. The high peak power allows also for cutting and ablating plastics, even if the laser wavelength does not match the linear absorption of the plastic.

The NanoWeld stations provide the ideal platform for the development and production of opto-electronic components, like singleand multi-channel transmitters and receivers. The station works with exchangeable trays and grippers accepting all device housing types and lenses, optical fibers or receptacles to be aligned and attached. Cycle times for the rapid mass production of TOSA type assemblies reach less than 25 seconds while it takes several minutes for complex devices.All components and subassemblies to build the NanoWeld station are of highest quality and performance. Even customized systems start from a common platform which minimizes development time and cost. By using device-specific trays and grippers, the time to change between different batch processes or device types is reduced to the minimum. Loading and unloading of these trays is performed on a separate loading station outside of the automated NanoWeld. The automated alignment starts from a known reference position.

NanoTest VCSEL measures VCSEL on wafer level or Chip on Carrier regarding their optical and electrical characteristics. The tester accommodates wafers with a diameter of up to 6 inches (150 mm), as an option also larger diameters can be integrated. A special interface mounted to the chuck also allows for testing Chip on Carrier devices.A high-precision motion system with XYZ and rotary adjustment brings the wafer chuck in the respective measurement position. First, electrical contacting takes place supported by a sideview camera. A high-precision current source delivers the operating current for the VCSEL under test.

All NanoTest stations combines precise measurements with high speed, proven reliability and ease of use. The versatility qualifies the stations not only for high volume quality assurance, but also for demanding development applications. This qualification helps to differentiate well-working devices from the ones with mediocre performance. In this way, unnecessary processing of low-quality devices is avoided early and possible problems during wafer production will be determined. NanoTest-W characterizes the optical and electrical behavior of VCSEL or Silicon Photonics chips on wafer level, while NanoTest-C is used for laser diodes, receivers and passive devices on bar or chip level.

Reliable Opto-Electronic Characterization for DC and RF Values The opto-electronic test station NanoTest PIC HD complies with all requirements for the testing of high-density photonics integrated circuits, such as silicon photonics structures or active PICs. Probe cards with up to several hundreds of contacts provide the connection for DC and RF measurements.

NanoSolder actively aligns optical components such as photonic circuits, waveguides, diode lasers and photodiodes. It uses selective laser soldering for the assembly. Compared to gluing with subsequent curing, much shorter assembly times will be achieved by selective laser soldering.

NanoHybrid provides a large degree of versatility. The active alignment, test and assembly station combines various assembly methods including gluing, laser welding or selective laser soldering. In addition, the station offers opto-electronic testing capability. Therefore, NanoHybrid is ideally suited for the development and small serial production in manufacturing companies or in research institutes.
