The thickness of surface finish can vary depending on the types of surface finish and applications. HASL, for example, has a thickness of 1-40 micrometers. However, it depends based on the specific requirements. On the other hand, ENIG has a thickness of 3-6 micrometers, and the gold layer has a thickness of 2-6 microinches. Thus, always refer to the specifications provided by your PCB manufacturers to ensure the consistency of your surface finish.<\/div><\/div><\/div><\/div><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-toggle-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-2063\" class=\"elementor-tab-title\" data-tab=\"3\" role=\"button\" aria-controls=\"elementor-tab-content-2063\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon elementor-toggle-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-closed\"><i class=\"fas fa-caret-right\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-opened\"><i class=\"elementor-toggle-icon-opened fas fa-caret-up\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-toggle-title\" tabindex=\"0\">Q3: Which is the cheapest PCB surface finish?\u200b<\/a>\n\t\t\t\t\t<\/div>\n\n\t\t\t\t\t<div id=\"elementor-tab-content-2063\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"3\" role=\"region\" aria-labelledby=\"elementor-tab-title-2063\"><div data-page-id=\"K5cQdPyqAoIVz9xiCVzcrjK4n2e\" data-lark-html-role=\"root\" data-docx-has-block-data=\"false\"><div class=\" old-record-id-VIvSds1JnokGWWxGglucirLXn4O\"><div data-page-id=\"PzvadCyLxoGC6axfsi0cBB2BnWf\" data-lark-html-role=\"root\" data-docx-has-block-data=\"false\"><div class=\"ace-line ace-line old-record-id-XizidTe9soWkg0xX1N9cjCycnJd\">A3: HASL is the cheapest surface finish of all types.
