Die Attach is one of the central steps in the manufacture of integrated circuits (ICs). In the first step, a wafer full of ICs is sliced up with a diamond dicing saw. After sawing, the individual ICs or «die» are picked off of the sawed wafer and placed onto a metal lead frame in the die attach operation. The lead frame has been prepared with an epoxy adhesive, which se- cures the die to the leadframe. In subsequent operations the metal pads on the die are connected to the metal leads of the frame providing an electrical connection to the print- ed circuit board to which the completed IC will eventually be attached. The high speed Z-axis of the die attach machine carries out the actual «pick and place» operation. The individual die are picked from a wafer and placed on the lead frame in a specific location. A machine vision system is used to accurately locate the independent positions, of both the die on the wafer and the leadframe where it will be placed. The accuracy of the joining of the two components is critical to the success of subsequent operations.

These are used in the field for the installation of optical fibre systems, for ex- ample for LANs (Local Area Networks). Using a high precision process, two optical fibres are fusion joined together. Great accuracy is required so that the transmission quality of the optical fibre is not significantly reduced. Two clamping devices, one for each fibre, accurately locate and hold the two optical fibres and are guided by SCHNEEBERGER NK1 roller tables. Prior to splicing, the fibre ends are precisely aligned to each other to sub-micron accuracy in three mutually orthogonal axes. This adjustment is effected using SCHNEEBERGER NK 1 tables driven by stepper motors. The accuracy of adjustment is monitored on a built-in LCD screen via an integral CCD camera system and controlled manually by means of a simple handwheel. Thereupon the fusion process takes place to produce a high quality, low-loss joint. This whole process takes on average one minute. Finally, the completed splice is protected by a heat shrink sleeve which is applied using the fusion splicers integral heatoven.

With a gripper installed on the top of the SCHNEEBERGER NDN 1 micro frictionless table, the components are picked from a large hopper. The parts are then placed on a specific position on the printed circuit board with a Z-stroke of the table. In this case, the NDN1 table is driven by a synchronous toothed belt. The SCHNEEBERGER NDN1 distinguishes itself particularly by its constant precision under the extra demands on service life and accuracy imposed by the high dynamic loading found in this application.

This application involves the measurement of glass fibre connections. The measuring procedure is based on the angle change of a reflector, in which the wave length of the laser beam is changed and evaluated. The mechanical rotation of the reflector is controlled through a stepping motor drive with a micrometer spindle. The stepping motor is installed on a roller table ND 1, in order to compensate for the longitudinal movement of the micrometer screw. This makes exceptionally high demands on the running char- acteristics of the roller table, since this has a direct influence on the measurement results.

All tables are equipped with type AC roller cages and type GB endpieces and can be mounted vertically or horizontally. The lower section includes standardized attaching holes. The sides opposite to the setscrews in the upper and lower sections can be used for mounting purposes. For the standard model stroke limiting is made by means of two screws in the upper section and one screw in the lower section. These screws can withstand only small forces or impacts in the direction of motion and should not be used as stops. With FORMULA-S these screws are no more necessary due to the cage assist system.
