The main methods are:
A, the use of high copper content, low impurity environmental protection copper, that is commonly referred to as non-magnetic copper rod. General connector shell color copper content of more than 59%, the inner conductor can be used iron and other impurities low bronze rods, bronze wire.
B, RF connector surface coating should be used: silver, plated ternary alloy, gold-plated (nickel can not).
C, the connector in the assembly or cable assembly, should pay attention not to have oil, impurities mixed to ensure the accuracy of parts, packaging should be environmentally friendly, clean.
D, RF connector electrical performance requirements, as well as shielding efficiency, power and other technical indicators.
