ENIG (Electroless Nickel Immersion Gold) is a surface finish used in the production of printed circuit boards (PCBs). It involves depositing a thin layer of nickel onto the copper pads and traces of the PCB, followed by a layer of immersion gold. (4 Layer ENIG PCB Board) The main advantage of ENIG is its flat surface, which makes it suitable for fine-pitch surface mount technology (SMT) components...

SMT (Surface Mount Technology) patch processing is one of the important processing methods in the modern electronics manufacturing industry. However, when performing SMT processing , various failures are often encountered. If these failures are not discovered and resolved in time, it will cause great trouble and loss to production. Therefore, this article will introduce the common faults and solut...

Proper surface finishing is crucial in PCB manufacturing to ensure high-quality, reliable circuit boards. It involves several steps before the assembly process to enhance solder ability, promote adhesion, and optimize electrical performance. Surface finishing is not only about the technology and methodology employed but also about the technology and methodology used. This will include ad...
