New White Paper: "Femtosecond Laser in Micro Production"
Abstract:
Generation of circuit outlines as well as producing openings in the substrate material to generate electrically conductive connections (e.g. through-holes) or mechanical windows are essential features of thin-film circuitry. As other demands on thin film circuits, like e.g. compatibility with various assembly methods and reliability have risen during the last years, also the requirements on the quality of the mechanical machining of the ceramic or flexible substrate materials have increased. Fabrication of vertical side wall interconnects to reduce the required surface area as well as tighter tolerances on outline features are driving the technical improvements.
This paper describes the application of a state-of-the-art laser machine equipped with a femtosecond laser source as high-precision tool for micro machining of flexible and ceramic substrate materials for thin film circuit manufacturing. The advantages of using last generation ultrashort pulse lasers are discussed and compared with a common laser process using a conventional CO2-laser source.
