HDMI HD Line Knowledge analysis

- May 04, 2017 -

Speaking of good wire, we first thought of affirmation is HDMI wire interface quality. The true interface has the main function in the stabilization signal transmission, absolutely cannot have the bad contact phenomenon. In metals, gold, silver, copper are very good conductive properties of materials, but because the price is expensive, the true full gold or silver wire is simply impossible to appear, the common is the entire copper interface, coupled with a layer of gold plating coating, to avoid oxidation. To pay attention to the gold plating coating may be in a period of time or several times after the fade, but this effect on the conductive performance is not very large. In addition to the interface material, wire quality is also a resolution of factors. Take all copper wire is generally soft and rich elasticity, the market for many wire sales are excellent, the copper content is low, the natural performance degradation. In addition, too soft or too thin wires may also clarify the wire shielding layer shrink, so here can not look at the appearance, but also to combine feel judgment. In addition, two can have the best shielding magnetic ring, perhaps wire rod body has a metal shielding network. To pay attention to the outside of some lines wrapped a layer of nylon nets, which has no practical effect on shielding trouble, need to be carefully differentiated.
