In determining the component designators, switch settings, and test points of the PCB, a prototype PCB's legend assists a design engineer. These are much needed for assembling, testing, and servicing them. Concerning PCB assembly and production there are three separate ways to print a prototype PCB's legend. Gold Finger PCB is one such thing. Here you will have an overview of the gold plating PCB connector process, commonly call gold fingers.

Gold fingers

For gold-plated connectors, gold fingers are the common name that runs on the edges of a PCB prototype. As they are gold, long, and thin, they resemble fingers, hence it is referred to as gold fingers.

Materials needed to manufacture gold fingers

From flash gold, which is one of the hardest golds around the manufacturing of gold fingers is done. The specifications of manufacture gold fingers need to be précised. The thickness should be in the range of 3Us to 50Us. There is the use of Flash gold in Plating Gold PCB because of its high level of the harness that makes sure that it will have a long working life without any need for repair.

What do gold fingers do?

Gold fingers are edge connector contacts that are used to electroplate the PCB's pads. Their major function is to prototype the PCB from deterioration and failures. If there is the right type of thickness and application then gold fingers can be used reliably for close to 1,000 cycles before the repair is required.

Application of gold fingers

For different things, gold fingers can be used. Based on the designer's purpose their use is specified. Few common applications of gold fingers are:

• It functions as an audio adapter.
• In transferring network data, it provides an interconnection point.
• It acts as a place for attaching daughter boards or specialized adapters.
• To the prototype PCB, it connects external components.
• Do gold fingers have any unique design specifications?
• Some design rules needs to be adhered to no matter how they are applied, including:
• Make sure to orient the Gold Finger PCB so that they face opposite the center of the PCB.

Never place plated through holes near the gold fingers.

The gold fingers should not have any solder mask or screen printing near them.
