Maintenance free system due to non contact drives The backbone of the machine is a high precision Impalla granite which was designed in a solid bridge construction. All positioning- and guiding systems are realized with air bearing solutions. Thus the axes have absolutely no contact with the granite. The drives are U-type linear motors. Just the cleaning of the machine is necessary. The scales have a resolution of 0.008mil and the temperature influence is almost nothing.

3D Topography Measuring
KORAD3D is a compact measuring unit which works on the principal of white light Interferometry.   The result is a 3D image of the measured object with a precision of 0.04mil on optical rough surfaces.
Non-Contact Laser Sensor
The principle of the measuring process is laser triangulation. A laser beam measures the depth of the surface. These depth point clouds generate best fit lines or patches. The sensor can be used to measure for example the depth of routed areas, height of pads or similar elements.
CCD Metrology
The metrology system is a powerful tool to measure nearly all applications in the PCB industry. A Matrix CCD camera with a 12x zoom objective deliver the image from the objects.  
High Speed Scanning
The high speed scanner system was developed to measure a high number of elements in a very short time especially for the PCB industry. The system is able to measure more than 1 million holes.
Precision Starts at the Base...
Ergonomic operation is very important for us. The operator works on a big operation panel which consists of a standard keyboard, mouse and 24" flatscreen monitor.
The CCD Metrology System
The metrology system is a powerful tool to measure nearly all application in the PCB industry. A Matrix CCD camera with a 12x zoom objective deliver the image from the objects. The measurement is based on edge detection. Functions like circle, arc, line, centre of gravity and lot more measurements can be done. The system measures on 2½ axes (XY and Z height).
Measurements can be made manually or inside of a recorded program fully atomized. The programming is very simple and easy to learn. The construction features like distance, point, arc are helpful tools to generate all application data which are needed . Many tolerance settings can be applied to the features. Even the taken objects can be calculated in different way’s like best fit, min superscribed, max inscribed calculation and more.
Programs for the automatic run can be generated manually or with the help of a DXF file of the target element. An optional NC-DXF converter is able to create DXF files in the right format from NC programs like Excellon, Posalux or Sieb & Meyer.
Depth measurements with a high precision can be done via auto focus on an object. Thus the distance calculation of different depth measurements makes it possible to measure the thickness or depth of varnish, depth controlled holes and depth controlled milled patches or scoring lines.
The biggest benefit of the CCD Metrology System is the dynamical light- and video edge detection adjustment during the measuring process. Thus the system is able to measure very complicate edges and objects.
The High Speed Scanning System
The high speed scanning system was developed to measure a huge number of drilled holes in a very short time with a very high precision. It was especially designed  for the PCB industry but includes also special features for other business areas. The scanning process of the whole area needs about 1 minute. An incredible measuring algorithm calculates thousands of elemends in some seconds. An optional top light system is also available. This can be used for blind via inspection or drill deflection evaluation. The top light is programmable and designed with fibre optics technique.
The operation of the scanning system is one of simplicity. As a manual programming process is not necessary, our machines load a nominal DXF file, scan over the part, and set the alignment holes to generate the complete measuring report. An array of statistic information is available, which includes but is not limited to Cpk, sigma, and average value. A deviation diagram immediately displays the quality of the measured products.
In the case of an error analysis, the objects do not need to be rescanned since all digitized pictures are stored on the system. A proX3 with the high speed scanner and the CCD metrolgy system makes it possible to combine the scanner result with the CCD camera. An element out of tolerance in the scan report can be checked again in more detail with the CCD camera. This feature saves time and generates a high inspection rate. The proX3 is the perfect tool for 100% accurate product control.
The new Scan-Contour measuring function is a quick measuring tool for 2-D objects. Lines, circles and arcs are probed with the “Best Fit” method and a speed greater than 700 features per second. The constructions of distances, points and angles are also possible. The input format is a DXF data set, which provides the optional NC-DXF converter and converts Excellon or S&M drill- and routing programs.
If all necessary elements refer to the nominal, an additional programming is not necessary. A freely programmable tolerance database can be set up. A first article report needs just some mouse clicks.
The free Step & Repeat function is an outstanding tool to measure the multiplicity of the same part without additional programming. Just simply place the parts on the table and the proX1 will automatically recognize the number of parts as well as their alignments and evaluate each object individually. In the complete display it is possible to immediately see which objects are inside or outside of the tolerance zone.
The operation is just as simple as the drill scanning. An internal wizard leads the operator through the menus and in a few minutes the measuring is complete.
