The parameters for the measurement of technical surfaces in the micro- and nanometer domain range from a simple acquistion of length in Cartesian coordinates to internationally standardized complex surface parameters for roughness, form and geometry. While for laboratory and development oriented work visualization of surfaces and 3D geometries is most important, judgement on good / bad criteria must be fully automated, based on parametric measurement results, in high volume manufacturing and critical quality assurance. In this connection, fast and reliable 3D image processing plays a decisive role in convertion of surface image data into reliable dimensional parameters. Solarius disposes of a long term experienced software team creating ideal solutions for image processing and complex machine control, being your ideal partner for challenging metrology tasks.

3D Roughness

Slowly replacing the evaluation of 2D profiles, optical 3D surface measurements enable the more informative roughness values of the ISO 25178, determining 3D surface characteristics. The Solarius Polaris 3D inspection provides ideal combination of resolution and speed to meet roughness acquisition requirements.

2D Roughness

2D roughness is a well established parameter describing evenness of a surface. Evaluation according to ISO 4287 provides internationally standardized roughness values for the control of technical surfaces. The Solarius Viking is an efficient profilometer to acquire ISO compliant 2D profile data on any surface and material.

Contour & Shape

Measuring 3D shape of an object is more than just measuring distances and heights. It is the exact determination of continous geometric parameters such as curvature, diameter, angle and texture. The ultra fast Solarius Atlas 3D interferometric sensors allow most robust 3D measurements in only a few milliseconds.

180614_Particles_web.png

Particle Inspection

3D particle inspection is most important when stacking functional devices, avoiding piercing of critical layers. Particles are separated from underneath surfaces and become measured in diameter, height and distribution. Contributing high 3D resolution Solarius Polaris inspection tools quickly detect even smallest particles.

Distance

Simple 2D distance measurements become complex when dimensions must be acquired at e.g. the bottom of trenches. Measurement of width between two points, lines or planes on complex 3D surface shapes can easliy be done using different Solarius Standard Products, available for individual scopes of application.

Volume

Measuring volumes of cavities or bodies goes back to determining 3D topographies in spatial dimensions, mathematically integrating derived measurement data to volumes. Depending on individual speed and accuracy requirements, Solarius Atlas and Polaris 3D inspection tools mark the ideal spead of available functionality.

Straightness

A surface is said to be straight over a given length, if the variation of the distance of its points from two planes, perpendicular to each other and parallel to the general direction of the line, remains within the specified. Surface straigthness is best measured by using the customizable Solarius AOP system platform.

Step Height

Differences in height can be measured at two or more "steps" where one of them serves as a reference plane. Step height results can be obtained from either single points, profiles or surfaces. A most cost efficient way to acquire step height data is unsing the Solarius Viking profilometers for 2D and 3D measurements.

Grain Analysis

Grain analysis is a part of mechanical process engineering linked to materials science. Material property is typically statistically distributed on surfaces. Primary goal of the grain size analysis is the determination of the prevailing particle size distribution. Ideal tools are the Solarius Polaris 3D microscopes.

180614_Flatness_web.png

Flatness

Flatness is the quality of having a created surface without raised areas or indentations. In metrology, flatness is indicated by tolerance limits defined by two planes, one above and one below the created surface, each parallel. Suitable 3D metrology for this purpose provide Solarius Atlas and Solarius AOP systems.

Bump Inspection

While wire bonding stays a method of choice for heavy duty connections in semicondutors, ball grid arrays (BGAs) are indispensable for 1st and 2nd level interconnects since many years. The arrays are tested for planarity, diameter uniformity, misplacement and missing items by the specialzed SEMI BGA inspection tool.

Waviness

Waviness determines, in addition to the roughness of a surface, its appearance, especially in paint finishes. For surfaces with mechanical function, the ripple is essential for lifetime and precision of the components. Solarius Atlas 3D measuring systems enable the testing of ripples on different object sizes.
