What is Gold Finger PCB? Gold Finger PCB is a type of printed circuit board that has gold-plated edge connectors. The gold plating provides a highly conductive and corrosion-resistant surface, which makes it an ideal choice for high-performance applications. The name "Gold Finger" comes from the gold-plated fingers on the edge connectors, which are designed to be inserted into a slot or socket. Th...

What is immersion gold PCB? The immersion gold circuit board adopts the method of chemical deposition, which generates a layer of coating through the method of chemical oxidation-reduction reaction. Generally, the thickness is thicker. It is a kind of chemical nickel-gold layer deposition method, which can achieve a thicker gold layer. In actual product applications, 90% of the gold boards are imm...

What is a gold-plated circuit board? The gold-plated circuit board is also called the electro-gold circuit board. It uses electroplating to plate a layer of gold on the surface of the pad of the PCB circuit board. The gold-plated board uses hard gold. The principle is to dissolve nickel and gold in chemical liquid, immerse the circuit board in the electroplating tank and turn on the current to for...

Immersion gold PCB (ENIG - Electroless Nickel Immersion Gold) and gold-plated circuit boards are both methods for applying a layer of gold onto the surface of a printed circuit board (PCB), but they use different processes and have distinct characteristics. ENIG Finish PCB uses a chemical deposition method. It generates a layer of coating through a chemical oxidation-reduction reaction. It is gene...
