Be gentle to avoid damaging the nearby components.<br><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Expose the Copper Trace:<\/strong>\n<ul class=\"wp-block-list\">\n<li>If the copper trace connected to the lifted pad is damaged or missing, you may need to scrape away the solder mask to expose the bare copper trace using a sharp hobby knife or fiberglass pen.<br><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Reattach the Pad:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Apply flux to the exposed copper trace.<\/li>\n\n\n\n<li>Using the <a href=\"https:\/\/www.anzer-usa.com\/resources\/soldering-iron\/\">soldering iron<\/a>, gently heat the exposed copper trace, applying a <a href=\"https:\/\/www.anzer-usa.com\/resources\/pre-tinning-solder-joints\/\">small amount of solder<\/a>.<\/li>\n\n\n\n<li>While the solder is still molten, carefully place the lifted pad back in its original position using tweezers. Ensure it aligns with the exposed <a href=\"https:\/\/www.anzer-usa.com\/resources\/pcb-traces\/\">copper trace<\/a>.<br><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Solder the Pad:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Once the pad is in place, continue heating the area with the soldering iron.<\/li>\n\n\n\n<li>Add a small amount of solder to bridge the connection between the pad and the copper trace. Ensure the solder flows smoothly and makes a good connection.<br><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Inspect Your Work:<\/strong>\n<ul class=\"wp-block-list\">\n<li>Use a magnifying glass or microscope to scrutinize your repair. Ensure there are no solder bridges or cold solder joints. The connection should be solid and without any visible defects.<br><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Test the Repair:<\/strong>\n<ul class=\"wp-block-list\">\n<li>After the repair, <a href=\"https:\/\/www.anzer-usa.com\/resources\/electronic-functional-testing\/\">test the circuit to ensure it functions correctly<\/a>.
