... nickel baths. One has the choice between an expensive coat-ing system or a subsequent infrared solidification which, in turn, also calls for further investment | MULTILAYER CIRCUIT | in facilities. The potential for a lead-free alternative For a lead free altenative provided the PCB manufacturer ensures optimal conditions for immersion nickel gold coating, | MULTILAYER CIRCUIT | the results of wave soldering are equally good to solder levelling. Good storage ability is also achieved by covering the pad and smd sides with | MULTILAYER CIRCUIT | gold. In our opinion, however, immersion nickel / gold will never become an established alternative to HAL. As already mentioned, the processing costs are the | MULTILAYER CIRCUIT | greatest handicap for this method. However, due to the lack of other alternatives in the lead-free future immersion nickel / gold will retain its position | MULTILAYER CIRCUIT | in the area of fine pitch and COB applications. Cost disadvantages of the immersion nickel / gold process could be balanced, in particular in the | MULTILAYER CIRCUIT | production of large series (consumer goods), if the ...

... to its original conditions after the stress has finished. Screen- printing inks, for instance, have a very high thixotropy. On account of the squeegee | MULTILAYER CIRCUIT | pressure and the movement the screen-printing ink becomes thinner and thus flows through the screen meshes onto the substrate to be coated. After lifting-off of | MULTILAYER CIRCUIT | the screen/stencil the ink must "stand"; it has to achieve its original condition rapidly and must not flow anymore, which ensures a good edge coverage. | MULTILAYER CIRCUIT | | TRACK / GAP: | Technical expression describing the minimum of conductor width (track or trace)  and the minimum Insulation width (gap) between two of | MULTILAYER CIRCUIT | them on a printed circuit board. Track/gap helps to define the degree of difficulty in the production of pcb`s. Track/gap is mostly measured in micron | MULTILAYER CIRCUIT | or in mil. | THROUGH CONNECTION | An electrical connection between conductive patterns on opposite sides of an insulating base, e.g. plated-through hole or clinched | MULTILAYER CIRCUIT | jumper wire | TRIM LINES | Lines which define the boarders of a ...
