Gold recovery Gold Finger from Circuit board computer scrap.
RAM Gold Fingers are the gold plated narrow connectors found on the edge of printed circuit boards to enable connections between multiple boards. They are made from flesh gold, the hardest form of gold available and work for a long time with superior conductivity. The thickness of gold fingers usually ranges from 3 to 50 microns.
Gold fingers are the gold-plated columns that you see along the connecting edges of printed circuit boards (PCBs). The purpose of gold fingers is to connect a secondary PCB to the motherboard of a computer. PCB gold fingers are also used in various other devices that communicate via digital signals, such as smartphones and smartwatches. Gold is used for the connecting points along a PCB because of the alloy’s superior conductivity.
Gold fingers are used as connecting contacts between two adjoining PCBs. Aside from its conductivity, the purpose of the gold is to protect the connecting edges from wear over many uses. Due to the strength of hard gold at its specified thickness, gold fingers make it possible for a PCB to be connected, disconnected and reconnected up to 1,000 different times in a corresponding slot.
