THROUGH-HOLE AND SURFACE MOUNT PRINTED CIRCUIT CARD CONNECTIONS FOR IMPROVED POWER COMPONENT SOLDERING
A system of circuit card components each include through-holes for soldering having recessed copper layers for thermal insulation. Thermal insulation prevents heat conduction away from flowing solder, allowing the solder to flow freely through the through-hole. Even high-temperature, lead-free solders may maintain the necessary temperature to flow. Different circuit layers include specialized features based on distance from a top or bottom surface. Vias surrounding the through-hole maintain the necessary cross-sectional area for electrical connectivity.
Machining Station and Method for Machining Workpieces
The disclosure relates to a machining station for machining platelike workpieces (1) by means of at least one tool (10, 13, 14). The machining station has a measuring device (16) for acquiring data relating to the position of bores, a drill (10, 13, 14) for generating bores in the workpiece (1), and a data processor (17) for processing data of the at least one measuring device (16) and/or for controlling the at least one drill (10, 13, 14). The data processor (17) is here suitable and set up for performing an adjustment between a desired drilling position and/or a desired bore depth and an actual position and/or actual depth as determined by the at least one measuring device (16) for a bore present in the workpiece (1), and adapting the drilling position and/or bore depth for generating bores by means of the at least one drill (10, 13, 14).
