What is a Gold Finger PCB? A gold finger PCB is a printed circuit board that features gold-plated contact fingers along one or more edges of the board. These gold fingers are essentially exposed copper traces that have been plated with a thin layer of gold. The gold plating on […]

Introduction to Immersion Tin PCB Immersion tin (IT) is a surface finish technique widely used in the printed circuit board (PCB) industry. It involves the deposition of a thin layer of tin onto the exposed copper surfaces of a PCB through an electroless plating process. Immersion tin PCB offers several […]

Introduction Flux is an essential component in the soldering process, as it helps to remove oxidation from the surfaces to be soldered and promotes the flow of solder. However, after soldering, the flux residue left on the printed circuit board (PCB) can cause various issues, such as corrosion, poor electrical […]

Understanding the Basics of a 6 layer pcb Stackup A typical 6 layer PCB stackup consists of the following arrangement of copper layers and insulating dielectric material: Layer Type Function 1 Signal Top layer for component placement and signal routing 2 Ground Ground plane for controlled impedance and shielding 3 […]

Introduction to Electronic PCB Assembly Electronic PCB (Printed Circuit Board) assembly is the process of soldering or mounting electronic components onto a printed circuit board. This process is a crucial step in the manufacturing of electronic devices, as it involves the integration of various components such as resistors, capacitors, transistors, […]

What is a Ground Plane? A ground plane is a layer of copper that covers most of the surface of a PCB, usually on the bottom layer or an inner layer. It is connected to the circuit’s ground (0V reference) through vias and acts as a return path for currents […]
