Accurate, models for vias in a multilayer circuit board are necessary to predict link performance in the GHz regime. This paper describes a methodology to build a high bandwidth, scalable first approximation circuit model using simple transmission lines of long vias typically used in thick backplane designs. System architects and backplane designers for example can quickly model various interconnect topologies for what-if scenarios and to set the direction for a more detailed design evaluation.
Fine Pitch Wave Soldering -
We did some evaluation to solder 0.4mm pitch by Wave. We found that there were many solder shorts at Sockets pins so it made touch up time longer. Please advise me someone has achieved the fine pitch soldering...
