microPREP™ PRO

Laser-Based Sample Preparation for Microstructure Diagnostics

The microPREP™ PRO system was developed to provide efficient laser sample preparation fitted to the needs of microstructure diagnostics and failure diagnostics. Therefore, with microPREP™ PRO material samples can be prepared effectively and economically by using an ultra-short pulse laser.

microPREP™ PRO allows to create complex and 3D-shaped samples to enable more comprehensive analysis of certain structures like in advanced packages, such as through silicon vias (TSVs), or even complete systems-in-package (SiP).

Furthermore, it is ideal to provide larger-sized samples with micron-level precision. The integrated overview camera assists in navigating on larger samples – the high-definition process camera allows for exact positioning.

Moreover, the application of a pico-second laser ensures virtually no structural damage and no elemental contamination of the material. In addition, microPREP™ PRO’s novel approach features substantially higher ablation rates in comparison to purely ion-beam-based processes.

The modular software design of microPREP™ ensures high flexibility for machining of samples for a broad range of microstructure diagnostics techniques. Based on machine-provided and customer-designed parameter-setups (recipes) microPREP™ PRO provides the best technology for sample preparation for:

  • Scanning Electron Microscopy (SEM),
  • Transmission Electron Microscopy (TEM),
  • X-ray Microscopy (XRM),
  • Atom-Probe Tomography (APT), and
  • Micromechanics.

Through ongoing development more and more areas of application are appearing on the market, in which microPREP™ PRO is able to assist in processing sample preparation for material analysis. Apart from mere preparation, samples can also be marked for easy tracking by microPREP™ PRO.

  • Free-form or box milling and line cut for quick access to the area of interest
  • Loading any kind of geometry into the system
  • Preparing cylindrical samples for XRM and synchrotron applications with the rotation tool
  • Multiple samples in one run enable more throughput
  • Motorized stages to find the area of interest as fast as possible
  • Recipe-driven Software for fast and easy sample preparation
  • Navigating with the overview camera to the area of interest

By using ultra-short pulse laser microPREP™ PRO is  best suited for sample preparation. Key benefits of micromachining with ultrashort pulsed lasers are particularly low structural damage, high power densities, and targeted precision on the micron scale. Thus, microPREP™ PRO is up for laser cutting and local laser thinning in metals, semiconductors, ceramics, as well as compounds and polymers.

microPREP™ PRO enables high-volume sample preparation for microstructure diagnostics and failure analysis.  Furthermore, the integrated COSnow Jet and the additional overview camera helps you to reduce your time to sample even more.
