Traditionally, increasing the thickness of gold plating was used to improve contact performance with lead-free solder. However, this approach failed to address fundamental issues\u2014particularly the deterioration of performance due to plating wear over time or after repeated cleaning. At Seiken, we\u2019ve taken a different approach. By adopting a new alloy with excellent contact properties, we eliminate the need for surface plating altogether. This solid alloy resists wear even after cleaning, ensuring consistently stable contact and long-term performance. The result is highly accurate, reliable testing for lead-free soldered electrodes in semiconductors and electronic components\u2014while fully complying with environmental standards like RoHS.\n            <\/p>\n<\/p><\/div>\n<figure>\n            <img decoding=\"async\" src=\"https:\/\/www.seiken.co.jp\/english\/wp\/wp-content\/themes\/wp-seiken-en\/assets\/images\/products\/probe\/lead_free_solder\/about_img01.jpg\" alt=\"Lead-Free Solder-Compatible Technology\"><br \/>\n          <\/figure>\n<\/p><\/div>\n<\/section>\n<div class=\"anchor\">\n<ul class=\"anchor_list container\">\n<li><a href=\"#feature\">Key Features &#038; Advantages<\/a><\/li>\n<li><a href=\"#usage\">Application Examples<\/a><\/li>\n<li><a href=\"#cases\">Custom solution examples<\/a><\/li>\n<li><a href=\"#related_products\">Related Products<\/a><\/li>\n<\/ul><\/div>\n<section id=\"feature\" class=\"container\">\n<h2>Key Features &#038; Advantages<\/h2>\n<div class=\"box -border\">\n<h3>01 Alloy materials improve wear resistance<\/h3>\n<p>Our alloy offers equal or greater hardness than conventional BeCu, even in ultra-small probe sizes such as P=130\u00b5m.
