After that, oxidation may start. To avoid this, EBest Circuit (Best Technology) uses vacuum-sealed bags with desiccants. Our storage process keeps boards clean and dry for up to 9 months. We also recommend using them within 90 days for the best results.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_is_the_OSP_Surface_Finish_Process\"><\/span>What is the OSP Surface Finish Process?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The <a href=\"https:\/\/www.bestpcbs.com\/blog\/2025\/07\/how-important-is-osp-surface-finish-for-hdi-pcbs\/\">OSP surface finish<\/a> process involves several precise steps:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Cleaning the copper pad:<\/strong> The surface must be free of oxidation, fingerprints, and oil. A thorough de-oiling step ensures uniform coating formation.<\/li>\n\n\n\n<li><strong>Micro-etching:<\/strong> Copper is etched by 1.0\u20131.5\u202f\u03bcm to create a slightly rough surface, which improves coating adhesion.<\/li>\n\n\n\n<li><strong>Applying the organic coating:<\/strong> After etching, an organic layer is applied. The PCB is then rinsed with DI water, with pH strictly controlled between 4.0\u20137.0 to prevent damage to the coating.<\/li>\n\n\n\n<li><strong>Drying and curing:<\/strong> The board is dried at 60\u201390\u202f\u00b0C for about 30 seconds. The exact time and temperature depend on the OSP chemistry used.<\/li>\n\n\n\n<li><strong>Solderability:<\/strong> The OSP layer thermally decomposes above 150\u202f\u00b0C during soldering, exposing clean copper for reliable joint formation.<\/li>\n<\/ul>\n\n\n\n<p>This detailed process results in a flat, solderable surface that supports high-density assembly without additional complexity or cost.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2025\/07\/Osp_surface_finish_4.png\"><img decoding=\"async\" src=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2025\/07\/Osp_surface_finish_4.png\" alt=\"What is the OSP Surface Finish Process?\" class=\"wp-image-10792\"\/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Thick_is_OSP_Surface_Finish\"><\/span>How Thick is OSP Surface Finish?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The typical thickness of <a href=\"https:\/\/www.bestpcbs.com\/blog\/2025\/07\/how-important-is-osp-surface-finish-for-hdi-pcbs\/\">OSP surface finish<\/a> ranges from 0.2 to 0.5 \u03bcm, depending on the chemistry and application method. While 0.25 to 0.35 \u03bcm is a common range, it&#8217;s not the only standard. If the coating is too thin (below 0.2 \u03bcm), it may not offer adequate protection and can oxidize quickly. If it&#8217;s too thick (over 0.5 \u03bcm), it could hinder solder wetting. At EBest Circuit (Best Technology), we maintain strict control over the OSP thickness to ensure consistent solderability and long-term protection.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Are_the_Applications_for_PCB_Surface_Finish_OSP\"><\/span>What Are the Applications for PCB Surface Finish OSP?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>OSP is widely used in cost-sensitive and high-density designs, where flatness and affordability are key. Common applications include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Consumer electronics<\/strong>: Remote controls, home appliances, and other high-volume, cost-driven products often use OSP for its affordability.<\/li>\n\n\n\n<li><strong>Wearables<\/strong>: Devices requiring lightweight, compact PCBs benefit from OSP, although it&#8217;s less ideal for assemblies requiring multiple reflows.<\/li>\n\n\n\n<li><strong>Tablets and smartphones<\/strong>: OSP supports the flat pad requirements of HDI boards, commonly found in mobile devices.<\/li>\n\n\n\n<li><strong>High-density boards<\/strong>: In PCBs with fine-pitch components or narrow spacing, OSP avoids bridging issues caused by thicker finishes like HASL.<\/li>\n\n\n\n<li><strong>General SMT assemblies<\/strong>: Any design where smooth, flat pads are needed to ensure reliable solder joints at a lower cost.<\/li>\n<\/ul>\n\n\n\n<p>However, OSP is not ideal for high-frequency signal boards (due to potential impedance variation) or assemblies requiring multiple reflow cycles, as the coating can degrade.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Choose_OSP_for_HDI_PCBs\"><\/span>Why Choose OSP for HDI PCBs?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>OSP is perfect for HDI. It\u2019s flat, cheap, and lead-free. That\u2019s a win for small components. But it does need care. At EBest Circuit (Best Technology), we\u2019ve solved the main problems:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Thermal issues?<\/strong>\u00a0We use high-temp OSP that resists up to 3 reflows.<\/li>\n\n\n\n<li><strong>Short shelf life?<\/strong>\u00a0Our sealed packs extend life up to 9 months.<\/li>\n\n\n\n<li><strong>Scratches or oxidation?<\/strong>\u00a0Our handling uses trays and gloves only.<\/li>\n\n\n\n<li><strong>Visual checks?<\/strong>\u00a0We combine OSP for pads and ENIG for test points.<\/li>\n<\/ul>\n\n\n\n<p>With the right practices, OSP works beautifully\u2014even for 01005s.
