OSP (Organic Solderability Preservative)

OSP (Organic Solderability Preservative) is a chemical treatment used to protect the copper surface of printed circuit boards (PCBs). It significantly improves the solderability of the board by forming a protective layer that prevents oxidation. This product is widely utilized in the electronics and semiconductor industries, where it plays a crucial role in ensuring reliable solder joints and extending the shelf life of PCBs. Notable properties include excellent adhesion, corrosion resistance, and compatibility with various assembly processes.
