While 3D AOI catches bad solder joints at the end of the line, the board has already been populated with expensive chips and baked through an oven. Fixing a bad solder joint post-reflow requires manual touch-ups or hot-air rework, which introduces thermal stress and drastically increases labor costs compared to simply wiping off raw paste at the SPI stage.<\/p>\t\t\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-1fc0e1c e-con-full e-flex e-con e-child\" data-id=\"1fc0e1c\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-3c442b5 e-con-full e-flex e-con e-child\" data-id=\"3c442b5\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-f363095 elementor-widget elementor-widget-text-editor\" data-id=\"f363095\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p><strong>What is the ideal solder paste height inspection tolerance?<\/strong><\/p>\t\t\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-ed06f29 e-con-full e-flex e-con e-child\" data-id=\"ed06f29\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-e99582e e-con-full e-flex e-con e-child\" data-id=\"e99582e\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-6483850 elementor-widget elementor-widget-text-editor\" data-id=\"6483850\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>While exact numbers depend on component pitch and stencil thickness (typically 100\u00b5m to 150\u00b5m stencils), standard industrial SPI process tolerances are generally set between <b data-path-to-node=\"43\" data-index-in-node=\"174\">70% to 130% for volume<\/b> and <b data-path-to-node=\"43\" data-index-in-node=\"201\">80% to 120% for height<\/b> relative to theoretical aperture calculations.<\/p>\t\t\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-4a6d31c e-con-full e-flex e-con e-child\" data-id=\"4a6d31c\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-5df0ea1 e-con-full e-flex e-con e-child\" data-id=\"5df0ea1\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-7dd8942 elementor-widget elementor-widget-heading\" data-id=\"7dd8942\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Does 2D SPI still have a place in modern SMT lines?<\/h2>\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-4eef7b7 e-con-full e-flex e-con e-child\" data-id=\"4eef7b7\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t<div class=\"elementor-element elementor-element-09a0c9d e-con-full e-flex e-con e-child\" data-id=\"09a0c9d\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-fa97363 elementor-widget elementor-widget-text-editor\" data-id=\"fa97363\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>For basic consumer electronics with large components (like 0805 passives or standard DIP connectors), 2D SPI can check basic area coverage.
