Poznámky redaktora
4. The parts are immersed aqueous passivation emulsion.12 8. Due the thinness the layer, the poor electrical conductivity nickel is insignificant.3 Nickel A 5-pm layer nickel applied protect large-surface parts, such earth panels.061 16.023 43. This surface protection used for aggressive environments. This can be very important, especially for small currents and low voltages. This surface protection sufficient for almost all industrial connectors applications.4. Silver produces moderate diffusion barrier.5 Copper 0.016 61 Zinc 0.21: 176 ____________________________________________________________ Material Specific resistance Conductivity in Ohm mm2 m in Ohm mm2 Aluminium 0. The contacts are silver-plated, with layer thickness pm.7. The brass contacts are first plated with 3-pm nickel layer (diffusion barrier) then with 2-pm gold layer the contact area.4 The Specific Resistance and Conductivity Various Materials Table 4. 4.017 58 Brass (CuZn40) 0.1 Silver The conductivity silver excellent, better than gold fact.3 . 4.2 Gold The finest surfaces are created with gold plating.5 Silver 0. The electrical conductivity gold significantly less than that silver, but due its constant contact resistance, used special applications.069 14.7. brownish sulphide layer easily develops its surface.067 15 Nickel 0.7.7.028 36 Gold 0.5 Tin 0
