Talking about what is the memory gold finger and its main function

For many people, the golden finger of memory is a relatively unfamiliar word. The gold finger of the memory refers to the part of the memory that contacts the contacts in the slot. It is to prevent oxidation. The part of the circuit is plated with gold of a few microns thickness, so it is called the "golden finger". All data streams and electronic streams of the memory processing unit are exchanged with the PC system through the contact between the gold finger and the memory slot, and are the output input ports of the memory, so the manufacturing process is very important for the memory connection. So what exactly is the golden finger of memory? Big guys often hear the word, but it may not be too familiar with it. The connecting finger of the memory is the connecting part between the memory stick and the memory slot, and all the signals are transmitted by the golden finger. The gold finger is composed of a plurality of golden conductive contacts. Because the surface is gold-plated and the conductive contacts are arranged like a finger, it is called a "golden finger". The gold finger is actually coated with a layer of gold on a copper clad plate by a special process because gold is highly resistant to oxidation and has high conductivity. However, because of the expensive price of gold, more memory is currently replaced by tin plating. Since the 1990s, tin materials have become popular. At present, the "golden fingers" of motherboards, memory and graphics cards are almost always used. Tin material, only some of the high-performance server /workstation accessories contact points will continue to use gold-plated practices, the price is naturally high.
