You must have seen PCBs with golden connectors. It is very much common in hard drives, memory cards, RAM, mobile phone components, graphics cards, and hundreds of other places. These are the main connectors that provide help in establishing an electrical connection of the gold finger PCB with another PCB.

The connectors are similar to fingers and are gold plated; thus, they are referred to as gold fingers, and the PCB is termed as gold finger PCB.

At the edge of the PCB, the connectors are placed and they make sure that the connection is proper. The use of cable connectors is eliminated by this technology as the PCB can be directly connected. It is a more efficient, reliable, and durable option.

You might have observed the distance between the fingers. This is to make sure that there is a separation of connections from one another. While designing the PCB the number of connectors, chemical composition, thickness, spacing, and other things is considered by gold finger PCB manufacturer.

Creating a reliable and long-lasting connection with the other PCB is the main agenda of creating gold fingers along the edges of the PCB. Gold fingers are used as a source of connection, and with a larger or the main PCB, they are connected.

Sometimes it becomes important to separate different functions in different PCBs. For example, the main PCB is the motherboard of the computer, but RAM is another form of PCB that works as temporary memory. From the main PCB it remains separated as a result you can take it out and reinstall it or replace it without any hassle.

In accommodating extra components or devices gold fingers provide help. You will find multiple RAM cards on a computer. So, it is totally on the user whether he wants to use an extra one or not. Similar is the case with memory cards.

Between the two PCBs, devices, peripherals, adapters, and external connectors, Gold Finger PCB provides a reliable means of connection. With the main PCB or power source, they connect the PCB. They transmit the signals from one PCB to another without any requirement of cable connectors.
