Hot air knives are then used to remove any excess solder, with the air knife modules adjusted to the melting temperature of the solder. Once the solder becomes solid, the boards are passed through a washer to remove any flux residue.<\/span><\/span><\/p>\n<p><span style=\"color: #748494; font-family: Open Sans;\"><span style=\"font-size: 17px;\">Some HASLs are configured at a ninety-degree angle to allow for complete immersion of the board in the solder bath, resulting in high-quality finishes. Alternatively, horizontal lines can be used, where the board is immersed in the solder through nozzles or rollers connected to the upper and lower parts of the panel. Through this horizontal process, a uniform thickness is achieved, unlike the vertical process where the impact of gravity can affect solder distribution.<\/span><\/span><\/p>\n<p><span style=\"color: #748494; font-family: Open Sans;\"><span style=\"font-size: 17px;\">HASL has good wettability and is preferred over other finishes because it can withstand solder material for a longer time without the use of any protective material. Finish quality can be measured through air pressure, board movement towards and away from the solder during dipping, and air knife angle.<\/span><\/span><\/p>\n<p><span style=\"color: #748494; font-family: Open Sans;\"><span style=\"font-size: 17px;\">Although effective for soldering components, the HASL surface is not compatible with fine-pitch elements due to its thickness. HASL deposition consists of a tin and lead eutectic mixture and is the best option for through holes and larger <a href=\"https:\/\/www.fs-pcba.com\/what-are-smd-components\/\">SMD components<\/a>. However, it is not the best option for SMD components less than 0805 in size.<\/span><\/span><\/p>\n<ul>\n<li><span style=\"color: #748494; font-family: Open Sans;\"><span style=\"font-size: 17px;\"><b>Lead Free HASL Finish:<\/b><\/span><\/span><\/li>\n<\/ul>\n<p><span style=\"color: #748494; font-family: Open Sans;\"><span style=\"font-size: 17px;\">Lead-free Hot Air Solder Leveling is a type of surface finish that uses lead-free solder alloys instead of the conventional Tin-Lead eutectic alloys used by HASL. The application process involves spraying molten solder onto the board to achieve the required wetting, followed by the use of hot air knives without lead. Once the solder becomes solid, the circuit board is passed through a washer to remove any remaining flux residue, similar to the HASL process.<\/span><\/span><\/p>\n<p><span style=\"color: #748494; font-family: Open Sans;\"><span style=\"font-size: 17px;\">Lead-free HASL is considered an environmentally-friendly alternative to standard HASL since it does not contain lead. However, it is less commonly used for surface finishing compared to other options such as <a href=\"https:\/\/www.fs-pcba.com\/enig-finish\/\">ENIG<\/a> and <a href=\"https:\/\/www.fs-pcba.com\/a-comprehensive-guide-to-osp-pcb-surface-finish\/\">OSP<\/a>, which are more readily available.<\/span><\/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-942ef3c elementor-widget elementor-widget-text-editor\" data-id=\"942ef3c\" 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;\"><span style=\"font-size: 17px;\">HASL surface treatment has a long history and most <a href=\"https:\/\/www.fs-pcba.com\/\">PCBA manufacturers<\/a> can provide this service, including FS Technology.
