Founded in 1988, MSC Polymer is an international production-oriented service provider headquartered in Staufenberg, Germany, specializing in the development, production and distribution of high end plastics for the PCB technology. Besides providing a wide range of consumable materials to the global PCB industry, MSC developed a revolutionary cross section method that enables much more simple cross-sectioning for high-end requirements, such as 2 to 4 mil laser micro-vias.

Cross sectioning process - three table top units

Workflow

  • Determination of the test specimen under the Mantis optics
  • Gentle milling-out of the specimen (up to 10 mm FR4)
  • Pre-separation with precision saw
  • Insertion of specimen in the mold (no additional registration aids such as pins, clamps, etc. are required)
  • Pouring of casting resin
  • (Fully automatic) sanding and polishing of specimen up to the center of the hole

Advantages of the MSC system:

  • Very high precision, i.e. also suitable for laser drilling
  • The microsection is standardized and can be executed quickly even by semiskilled personnel
  • High throughput volume is possible; a single person can process > 100 specimens/layers
  • Significant reduction of material consumption (sand paper, resin, etc.)
