Thank you for your responses! I still think that the solder acts as a "bottleneck" as current flows throught the cable, i.e. the copper cables have a conductivity of a 100 and the solder of the order of 40 depending on its composition. In other words the solder has a much greater resistence to the current flow than the copper. Am I mistaken?? Therefore I think that by having a expensive/exotic cable is a waste of money since ultimately the solder resistance is the one that determines the "quality" of the current transfer to the device being feed. Any more comments?
Expensive cables/connector and solder
Why there is so much intest about buying expensive cables/connector made of exotic materials if the end wires are thinned? I understand that the solder used in most applications is 60-40 lead-tin or so. Then is the conductivity of the solder as good as the copper or whatever exotic material is used to make the cable/connector?
