Notes:
Mastertool MT8 is a new dry phototool for the production of printed circuit boards, which represents a completely new technology. MT8 is not sensitive to daylight, is free of silver and inherently environmentally safe as the material does not contain any toxicingradients, no processing chemicals are required and no waste arises. For imaging, thenon-transparent thin bismuth layer of MT8, embedded between polymers, is agglomerated intobeads through IR laser radiation, making this area optically transparent. Light and electron microscopy as well as X-ray diffractometry are used to characterise thecomposition of the material and the details of the recording processes. Based on finite elementmodelling, it was possible to interpret theoretically the experimentally determined dependence of thesensitivity on the recording speed. Understanding these material properties enables plotter optimisationfor MT8.
