Brass Contact Goldfinger Goldfinger refers to the cost of board and senior will be gilded on the surface, that white is the conductor. Goldfinger common applications such as computer memory on a row of yellow strip, there are old-fashioned card games consoles on the card, this cheat more often. Goldfinger is actually on the CCL through a special process and then covered with a layer of gold, because gold is extremely Goldfinger oxidation resistance circuit board processing, but also very strong conductivity. In general, if the computer hardware maintenance, we will often mention Goldfinger Goldfinger circuit board production, where in fact, refers to memory, graphics cards, sound cards, network cards and other cards and socket connection component finger board, Generally, we can use the eraser to gently wipe, you can reduce the degree of oxidation Goldfinger, thereby enhancing its connectivity, and then solve the problem of a small part of the hardware connection.

Soft gold plating, the gold is very thin, only a few seconds electricity, generally the entire board plating line. Shen gold plate definition, nickel and gold plating is not up, but the reduction reaction by chemical immersion up, the cost is higher than the soft gold plating, the board welding is better, but do not wear finger position. There should be one of the best is the outside, the inner panel patch and plug hole locations immersion gold or HAL, and only Goldfinger bit Gold, Gold spot where we usually called hard metal, very thick, resistant plug, of course, Shen Jingui price ratio.
