It is also known as anti-tarnish. The <b>OSP PCB process<\/b> involves applying a layer of organic finish onto a clean copper surface through an adsorption process.<\/span><\/p><p><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">The organic finish helps to protect the copper from oxidation and the effects of moisture and environmental pressure. During the soldering process, the finish can be easily removed through the use of <a href=\"https:\/\/www.fs-pcba.com\/pcb-flux\/\">PCB flux<\/a>. This allows the clean copper to mix with the melting solder, producing solder joints in less time.<\/span><\/p><p><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">The compound used in <b>OSP surface treatment<\/b> is a water-based compound that is part of azole groups, such as benzimidazoles, imidazoles, and benzotriazoles. These compounds are absorbed into the copper surface, creating a film. The thickness of the film generated by benzotriazoles is thinner than that of imidazoles. Typically, the film has a thickness of tens to hundreds of nanometers.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c28961c elementor-widget elementor-widget-heading\" data-id=\"c28961c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-large\">Features of OSP PCB surface finish<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e8678a0 elementor-widget elementor-widget-text-editor\" data-id=\"e8678a0\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<ul><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">Boards created using OSP are easy to manufacture and can be easily reworked if needed, which is why <a href=\"https:\/\/www.fs-pcba.com\/\">PCBA manufacturers<\/a> often use a fresh coating to repair damaged layers.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">Bare board\u00a0have good wetting properties during soldering on vias and pads.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">This is an inexpensive option and is commonly chosen by electronics manufacturers.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">The lead-free feature of OSP PCB plating makes it suitable for SMD components and PCBA processing through <a href=\"https:\/\/www.fs-pcba.com\/smt-pcba\/\">SMT assembly<\/a>.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">Its flat surface makes it suitable for tight pitch pads such as BGA and QFP.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">Created using a water-based compound that is safe for people and the environment.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">It requires less solder mask ink compared to other surface finishes.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">Susceptible to mechanical damage, so requires more care in handling.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">The colorless and transparent state makes visual inspection difficult for operators, and its thickness is difficult to measure, which may affect welding performance.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">Due to its fragile nature, it requires careful transportation and handling to avoid scratches and damage to the protective layer.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">It is not suitable for plated through holes as it has a short shelf life of around 6 months.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">Is a sensitive finish and even minor water or moisture can affect its performance.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">The OSP process requires certain variations and is not compatible with ICT, which can cause damage to the PCB with ICT probes.

This diagram is divided into different blocks that define each step in the manufacturing process.<\/span><\/p><ol><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">The first step is cleaning, which removes organic contaminants such as oil and oxidation films from the copper foil, the main component of the OSP. Insufficient cleaning can result in an uneven thickness of the created preservative. To achieve high-quality OSP films, the concentration of the cleaning liquid must be within a certain range according to laboratory standards. The cleaning process must be regularly monitored to ensure the required standard is met. If the desired results are not achieved, the cleaning liquid should be changed.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">The second block is Topography Enhancement, where micro-etching is used to remove the oxidation produced on the copper foil that causes strong bonding between the copper foil and organic solderability preservative solution. The film build rate depends on the micro-etching speed. To achieve a smooth film thickness, the speed of micro-etching must be stable. The range for micro-etching speed is about 1.0 to 1.5 micrometers per minute.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">The best option is to use a rinse before creating the preservative, as OSP solution can get polluted by ions, which can cause tarnishing after the completion of the reflow soldering process. In addition to that, DI rinse must be used after the creation of the preservative with a pH value of 4 to 7. If these parameters are not followed, the preservative can be destroyed due to pollution.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">The OSP PCB coating is then applied to the cleaned copper surface through an adsorption process. The OSP solution contains organic compounds such as benzimidazoles, imidazoles, and benzotriazoles that form a thin layer on the copper surface. The thickness of the coating can be controlled by adjusting the concentration and immersion time of the solution.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">After the coating is applied, the PCB is dried and cured in a controlled environment to remove any remaining moisture and to ensure proper adhesion of the OSP layer.<\/span><\/li><li><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">Once the coating is applied, the PCB is inspected for any defects or irregularities. The OSP-coated circuit boards\u00a0are then subjected to various <a href=\"https:\/\/www.fs-pcba.com\/pcba-test\/\">PCB tests<\/a> to ensure their quality, reliability, and performance.<\/span><\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9f1af5d elementor-widget elementor-widget-heading\" data-id=\"9f1af5d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-xl\">OSP Problems after Soldering<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-fcfc463 elementor-widget elementor-widget-text-editor\" data-id=\"fcfc463\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><span style=\"color: #748494; font-family: Open Sans, sans-serif;\">Here are some suggestions that can be used in open nitrogen conditions for secondary reflow to achieve good welding results.
