With your Au selection, a standard 30-degree bevel will be added to your edge connector. We can also bevel at 15 or 45 degrees upon request. For multi-layer boards please insure adequate inner layer back set for the bevels. Gold Finger is the memory and the memory slots on the connection between the parts, all the signals are transmitted through the finger to. Gold finger by numerous golden composed of conductive contacts, but also because of its gold-plated conductive surface such as a finger-like arrangement of the contacts, so called "Gold finger." Gold finger is actually in the CCL through a special process and then covered with a layer of gold, because gold is very strong antioxidant activity, but also very strong conductivity. But because of the expensive price of gold is currently more memory are used instead of tin from the 90s of last century began to spread solder material, the current motherboard, memory and graphics cards and other devices "Gold finger" are almost always used tin material, only some high-performance server/workstation accessories will continue to use gold-plated contact point approach, the price of natural cheap.
Finger edge connectors are usually inserted into the mating groove to ease the connector. When this happens, the heart of the aircraft may be exposed copper if they do not quit this advantage fully. We will take you back to the inner layer of copper is higher than shown on the right in order to avoid exposure to copper in this location. Copper can cause direct exposure to all terminals short connector into it.
