Agustin Coelle Vera<\/span><\/strong><strong><span style=\"text-decoration: underline;\">:<\/span><\/strong><\/p><p>Due to the global transition of the electronics industry towards lead-free solutions, the space industry increasingly faces challenges related to the unavoidable use of Electrical, Electronic, and Electromechanical (EEE) parts with lead-free finishes, necessitating effective risk management strategies. The rising use of commercial off-the-shelf (COTS) components, especially in the rapidly growing constellation market sector, has led to the European space industry utilizing a significant number of components with lead-free finishes, even when high-reliability leaded versions are available. Although the space sector is exempt from RoHS, it is not from REACH and these regulations coupled with market dynamics may eventually affect the availability of leaded solder paste.<\/p><p>A new project, LETTERSS (Lead-free Transition for the European Space Sector, 101135428), has received funding from the EU (Space R&amp;D Programme, HORIZON-CL4-2023-SPACE-01 call) to address the main challenges of the Pb-free transition for the European Space Sector described in the Roadmap delivered in 2020 by the ESCC Task Force. The methodologies used in the Project to overcome the current challenges that impede the broader use of Commercial Off-The-Shelf (COTS) components in space projects with existing qualified assembly processes based on leaded solders will be discussed. Additionally, there will be a presentation on the comprehensive evaluation of two lead-free solders that show promise for the Space Sector, including reliability model development.<\/p><p>\u00a0<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-7320947 e-con-full e-flex e-con e-child\" data-id=\"7320947\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-6ba59d9 elementor-widget elementor-widget-text-editor\" data-id=\"6ba59d9\" data-element_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<p>\u00a0<strong><span style=\"text-decoration: underline;\">Abstract of Dr. Guillaume Meyer&#8217;s presentation: the Tin Whiskers Challenge<\/span><\/strong><\/p><p>With the potential application of the Restriction of Hazardous Substances (RoHs) legislation to the aerospace industry, lead-free finishes cannot be avoided in electrical, electronic and electromechanical parts. Besides the difficulties of finding lead-free alternatives that offer comparable or superior performance to Pb solders on a stable economic basis while being compliant with regulation requirements, metal whiskers are of concern. These crystalline filaments can grow out of the surface up to some millimetres and may lead to short circuits or electrical failures in electronic components. Industrial accelerated whisker testing procedures do exist, but they do not provide the ability to predict in-orbit service time.<\/p><p>The present contribution introduces the tin whisker activities undertaken in the framework of the HORIZON project named LETTERSS (\u201cLead-Free Transition for the European Space Sector\u201d). It is proposed to advance the understanding of the interactions between factors influencing the whisker phenomenon and provide a heat map for whisker growth risk and whisker acceleration test conditions for future characterization and mitigation procedures for selected lead-free solders. Based on a literature survey, the identified driving parameters will be presented while preliminary results on variation of coating thickness and environing temperature will be shown as well.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-c8bfea0 e-con-full e-flex e-con e-child\" data-id=\"c8bfea0\" data-element_type=\"container\">\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-8c5026a e-con-full e-flex e-con e-child\" data-id=\"8c5026a\" data-element_type=\"container\">\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-3388840 e-flex e-con-boxed e-con e-parent\" data-id=\"3388840\" data-element_type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-6ff6968 elementor-widget elementor-widget-text-editor\" data-id=\"6ff6968\" data-element_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<p><span style=\"color: #ffffff;\">y<\/span><\/p><p><span style=\"color: #ffffff;\">y<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>ACCEDE &#8211; ESCCON Conference 2025 Date: 25th &#8211; 27th March 2025 Location: Seville, Spain Complete programm of the event here.
