Test technology for surfaces: MPH Automation

The testing of modern shiny or reflective surfaces has been one of the biggest challenges in the field of automated component testing. Until just a few years ago, there was no proper technology for the camera-aided testing of reflective, mirroring surfaces. Such camera testing technology is now available, and MPH Test Automation has already used it many times for surface inspection and component testing – for metal, electroplated parts, plastics, semiconductors, glass, and more. The principle is always the same, with damage in the µm or mm range. This technology can even be used for 100% testing of the surfaces of safety-relevant components. We will be happy to tell you more about how this works on request.

Standardised test cells for reflective surfaces

Perfectly polished surfaces without scratches – this is the requirement always placed upon tested parts. MPH Test Automation now uses standardised test technology modules for these tests. The test cell loading method is based on a carrier system that conveys several trays to the machine and places them beneath the camera test technology components. Multiple components can generally be transported in these trays, and a complete shift can be completed without interruption. OK parts continue along the process, whereas defective parts are ejected. Loading and unloading take place using SCARA robotics or with the robotics technology of the customer's choice. Whether you prefer Stäubli, Mitsubishi, or Fanuc robotics, we are happy to go with your requirements. The same applies to the control technology.

Surface test technology in cleanroom conditions for semiconductors etc.

MPH Test Automation's technology is also geared up for special cleanroom applications. For example, in the case of wafers requiring gluing, we measure the height of the applied adhesive in a cleanroom by means of a profile scan. In the case of ceramic substrates, we measure the values of the printed resistors in cleanroom conditions. Here, we do not have any standard robots; instead, special robots from Genmark or ISEL are integrated into our systems. It is important that none of the moving parts creates any particles here. We have lots of experience in building automation solutions that meet cleanroom criteria. After all, ultra-precise production processes in cleanroom environments are increasingly controlled using fully automated machines. We deliver solutions for the following:

  • The stacking or sorting of wafers
  • The creation of profiles of surfaces
  • The visual inspection of surfaces
  • The integration of standard robot systems
  • The transport of special parts (special paddle)
  • Contact-free measurement and testing, recognition and classification of parts
