Real-time monitoring and advanced analysis of profile data

Profiling provides a simple, cost-effective alternative to machine vision systems to verify the presence of components, identify surface defects, detect incorrect assemblies or monitor planarity in flat parts. The use of digital process signature technology provides a picture of each part along with multiple points of measurement to deliver repeatable, fast and accurate pass/fail inspection.

Sciemetric’s non-contact profile testing uses a sigPOD to monitor lasers, linear encoders and rotary encoders, capturing the full digital signature at a high speed. The sigPOD also enables analysis of specific zones on a part, flexible measurement of parameters and statistics for smoothing the signals. Following are some examples on profiling applications.

What can be monitored:

  • Part or seal presence
  • Part or seal location and assembly flatness and verification
  • Stack up tolerances

Faults that can be determined:

  • Improper assembly
  • Missing components
  • Defective components or stack ups.

Profiling Application Stories

Laser profiling and profile signatures provide real results for OEM

A manufacturer of heavy equipment was experiencing issues with a major assembly and required an in-process test to detect improper assembly, missing components and component defects.

Using a single 2D scanning and image laser, Sciemetric collected the profile signatures for the part providing a reliable, real-time means to verify bearing seal part/seal presence, part/seal location and assembly flatness, and stack-up tolerances.

Precision finishing for advanced semiconductors

A manufacturer of sophisticated polishing pads used in the production of advanced semiconductors needed to verify the grooves on the grinding edges of these pads met spec for depth and spacing. Any imperfection can lead to expensive quality meltdowns when a semiconductor is installed in the end product.

Sciemetric delivered a laser profiling system to map the contours of the grinding surface. Sciemetric’s analysis software then identified any non-uniform surface characteristics. This enabled the manufacturer to boost the quality of its products and demonstrate to its customers the rigor of its testing and quality assurance process.
