CCD metrology measurement system

The metrology measurement system offers the highest 2-dimensional accuracy. Objects and contours can be captured using a wide variety of measuring tools. The live image of the CCD camera can be enlarged and reduced using a 12x zoom lens.

High Speed - Scanner

The scanner was specially developed for the precise measurement of a large number of elements in the PCB industry. More than a million elements can be measured. Various forms, such as holes, contours, gold pads, can be scanned and evaluated.

Tactile 5-way sensor

Different lengths and contact balls can be selected from a large variety of probe tips. The probe tip can be replaced quickly and easily using a magnetic coupling. The metrology system executes the fully automatic positioning to the object and determines its position by gently touching it.

The little brother of the proX3 ...

... but in terms of function and accuracy, hardly inferior to the "great role model". In the revised and improved proX2 CNC, the best possible compromise between price and performance was realized. With the help of the fully automatic vacuum table, even the most difficult materials can be held and measured with great precision. The machine is loaded onto a vacuum solution in just a few seconds by mouse click.

Magnetic quick coupling system for an even larger image size

The 12x zoom lens enables a wide variety of image sizes for optimal evaluation of the contours. If very high zoom is required pretty often, i.e. when measuring conductor runs, the measuring machine can be expanded with an additional lens. A magnetic quick coupling system enables simple and convenient retrofitting.





The Metrology SystemIK5000

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.

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 measuring machine 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 measuring machine 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. The free Step & Repeat function is an outstanding tool to measure the multiplicity of the same part without additional programming.

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.

Extended design, testing with ISO tolerances and measurement results in the part view or in the camera image

Extended constructions with the already measured elements are no problem. This creates projections or new zero points, but also the necessary distances or intersections. All measurement results can be checked for dimensional accuracy using ISO tolerances. Completely new in this branch is the possibility to freely integrate the measurement results into the live image or the parts view as desired. Simply tap with your finger and position the desired result type freely on the screen. This means that all results are displayed in a flash and you can print or export this type of display. Confusing result lists without reference to the measurement object are a thing of the past. It is of course also possible to export result lists in standardized formats for further processing or statistics.
