  In the realm of printed circuit boards (PCBs), the immersion tin process holds a crucial position. This article aims to elucidate the intricacies of immersion tin plating on PCBs, providing a comprehensive overview of its process, significance, and applications. What is Immersion Tin? Immersion tin , also known as organic solderability preservative (OSP), is a surface finish applied to PCBs to protect the copper traces during storage and assembly. It ensures the preservation of copper and facilitates solderability, playing a pivotal role in the PCB manufacturing process.   The Process of Immersion Tin on PCBs Surface Preparation Before immersing PCBs in the tin solution, thorough surface preparation is imperative. This involves meticulous cleaning to remove any contaminants or oxidation from the copper surface. The cleanliness of the copper directly impacts the quality and efficacy of the immersion tin process. Activation Activation is a crucial step that primes the copper s...
