What does the golden finger in the computer mean?

The golden finger (connecting finger) is the connecting part of the memory strip to the memory slot, and all signals are transmitted through the gold finger. The golden fingers are made up of gold-plated conductive contacts, which are called "Golden fingers" because of their gilded surface and the conductive contacts arranged as fingers. The gold finger is actually on the CCL through the special process to cover a layer of gold, because the gold is very strong oxidation resistance, but also very strong conductivity. But because of the high price of gold, more memory is now used to replace the tin, since the beginning of the 90 's, tin materials began to become popular, the current motherboard, memory and graphics devices such as "gold fingers" are almost all the use of tin materials, only some high-performance server/workstation accessories Contact point will continue to use gold-plated practice, The price is naturally very expensive.

All the data flow and electronic flow of the memory processing unit are exchanged with the PC system through the contact of the gold finger and the memory slot, which is the output input port of the memory, so the manufacturing process is very important for the memory connection.

Now, all DIY accessories and motherboard slot connection parts are called Goldfinger.
