The Next Generation OSP: Proven To Perform

Modern Pb-free assembly environments are tough on surface finishes, particularly OSPs. Multiple exposures to higher temperatures for longer times, can make coatings break down and fail to perform. Which results in poor yields, reduced reliability, and higher costs. M-Coat HT is MacDermid’s production-proven OSP process specifically designed to perform in harsh, Pb-free manufacturing settings. Our coating’s thermal durability provides consistent surface wetting, color uniformity, and solderability through multiple reflow cycles. When it comes to process simplicity, coating durability and reliability, M-Coat HT is the right choice.
