Real-world case studies reveal that every step\u2014from the uniformity of copper surface micro-etching and the stability of electroless nickel deposition to the precise control of the activation process\u2014directly impacts the quality of the final PCB immersion gold finish. These critical details are often magnified, particularly in thick copper boards, high-frequency boards, and multilayer boards utilizing mixed laminates. A truly reliable process requires careful tailoring based on the specific characteristics of the board material and the environmental..."}
