Modern green or UV lasers allow for &#8220;cold marking,&#8221; which prevents heat damage to the sensitive internal circuitry.+1<\/li>\n\n\n\n<li><strong>PCB Serialization:<\/strong> Marking solder masks or substrates on Printed Circuit Boards (PCBs) for lifecycle tracking.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">2. Precision <a href=\"https:\/\/www.lasercutting-world.com\/Products\/Platelasercuttingmachine\/\">Laser Cutting<\/a> &amp; Drilling<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">As boards get denser, traditional mechanical drills simply can\u2019t keep up with the required hole diameters.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Micro-via Drilling:<\/strong> Lasers create incredibly small holes (vias) in multi-layer PCBs, often smaller than <strong>50 \u03bcm<\/strong>, to connect different layers of circuitry.<\/li>\n\n\n\n<li><strong>Wafer Dicing:<\/strong> Using &#8220;stealth dicing,&#8221; a laser focuses inside the wafer to create a localized layer of damage. The wafer is then separated by expanding a tape, resulting in zero kerf (material loss) and no debris.+1<\/li>\n\n\n\n<li><strong>Flex-Circuit Trimming:<\/strong> Cutting polyimide or other flexible substrates for wearable tech where shapes are complex and tolerances are tight.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">3.
