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
Desktop routing machine with Mantis optic
Precision saw with cross-sectioning machine
Z-axis-controlled grinding and polishing machine
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.)
