A resin matrix made of epoxy resin, which is most commonly used for printed circuit boards, shows a typical range of heat absorption (endothermic behavior) above 120\u00b0 C. This range corresponds to the softening range of the PCB. This area corresponds to the softening area of the resin matrix, also known as the glass transition area. The center of the range is defined as the glass transition temperature (i.e. Tg value). If the heating process is repeated with the same PCB sample and a shift in the Tg value is detected, this is referred to as post-curing.<br \/>This means that the PCB sample tested was not yet optimally cured. In this way, pressing programs in PCB production can be adapted and optimized for specific materials.<\/span><\/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-17cf479 e-con-full e-flex e-con e-child\" data-id=\"17cf479\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-e1b3ef5 elementor-widget elementor-widget-image\" data-id=\"e1b3ef5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"568\" height=\"568\" src=\"https:\/\/www.ksg-pcb.com\/wp-content\/uploads\/2024\/04\/Tg-Bestimmung-Ofen-rotated-e1713945617745.jpg\" class=\"attachment-medium_large size-medium_large wp-image-11349\" alt=\"Tg determination in the oven\" srcset=\"https:\/\/www.ksg-pcb.com\/wp-content\/uploads\/2024\/04\/Tg-Bestimmung-Ofen-rotated-e1713945617745.jpg 568w, https:\/\/www.ksg-pcb.com\/wp-content\/uploads\/2024\/04\/Tg-Bestimmung-Ofen-rotated-e1713945617745-300x300.jpg 300w, https:\/\/www.ksg-pcb.com\/wp-content\/uploads\/2024\/04\/Tg-Bestimmung-Ofen-rotated-e1713945617745-150x150.jpg 150w, https:\/\/www.ksg-pcb.com\/wp-content\/uploads\/2024\/04\/Tg-Bestimmung-Ofen-rotated-e1713945617745-45x45.jpg 45w\" sizes=\"(max-width: 568px) 100vw, 568px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">DSC: Furnace with PCB sample and reference each in an aluminum crucible<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\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-7ad7453 e-con-full e-flex e-con e-child\" data-id=\"7ad7453\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-365f03c elementor-widget elementor-widget-heading\" data-id=\"365f03c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">TMA - Thermal Mechanical Analysis<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ae89e47 elementor-widget elementor-widget-text-editor\" data-id=\"ae89e47\" data-element_type=\"widget\" data-e-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\t\t<p>In thermomechanical analysis (TMA), the physical property changes of the PCB are measured as a function of temperature under a constant load.\u00a0<span style=\"font-style: inherit; font-weight: inherit; text-align: var(--text-align); color: var( --e-global-color-primary );\">To determine the Tg value, a sample is clamped in the TMA apparatus and heated in a controlled manner. During the heating process, the dimension or coefficient of expansion of the sample is measured continuously. Typically, the expansion rate of the material changes significantly when the glass transition temperature is reached: below the Tg the material is hard and brittle, above it is softer and more flexible. This change leads to a characteristic kink or flattening in the thermomechanical curve, which marks the Tg value.\u00a0<\/span><span style=\"color: var( --e-global-color-primary ); font-style: inherit; font-weight: inherit; text-align: var(--text-align);\">This offers the advantage that direct dimensional changes in the material are measured in response to a change in temperature. Therefore, this method can even be used with very small samples. However, with particularly weak transitions, the sensitivity of the measurement can be lower than with DMA and DSC.<\/span><\/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-58c4dc6 e-con-full e-flex e-con e-child\" data-id=\"58c4dc6\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-c2d0338 elementor-widget elementor-widget-heading\" data-id=\"c2d0338\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">DMA - Dynamic Mechanical Analysis<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-071f25c elementor-widget elementor-widget-text-editor\" data-id=\"071f25c\" data-element_type=\"widget\" data-e-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\t\t<p>In dynamic mechanical analysis (DMA), a sample of the PCB base material is subjected to an oscillating mechanical stress while it is heated in a controlled manner. The DMA records the changes in a storage modulus (measure of stiffness) and in a loss modulus (measure of damping). A marked drop in the storage modulus together with a peak in the loss modulus indicates the Tg, where the material transitions from a glassy to a rubbery state. DMA therefore provides comprehensive information about the mechanical behavior of the PCB material (stiffness, damping) over a wide temperature range and is very sensitive in detecting transitions, even if they are very weak. DMA can provide module data that is useful for mechanical specification. A disadvantage is the comparatively more complex preparation and execution of the test. The analysis and interpretation of the results can be more complex than with TMA or DSC.<\/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\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-6e04410 e-flex e-con-boxed e-con e-parent\" data-id=\"6e04410\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-73c0609 e-con-full e-flex e-con e-child\" data-id=\"73c0609\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-0c54272 elementor-widget elementor-widget-image\" data-id=\"0c54272\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/ksg-pcb.com\/wp-content\/uploads\/2024\/05\/Tg-Bestimmung-Diagramm.png\" data-elementor-open-lightbox=\"yes\" data-elementor-lightbox-description=\"Diagramm Tg-Wert Messkurven\" data-e-action-hash=\"#elementor-action%3Aaction%3Dlightbox%26settings%3DeyJpZCI6MTE1ODIsInVybCI6Imh0dHBzOlwvXC93d3cua3NnLXBjYi5jb21cL3dwLWNvbnRlbnRcL3VwbG9hZHNcLzIwMjRcLzA1XC9UZy1CZXN0aW1tdW5nLURpYWdyYW1tLnBuZyJ9\">\n\t\t\t\t\t\t\t<img decoding=\"async\" width=\"768\" height=\"390\" src=\"https:\/\/www.ksg-pcb.com\/wp-content\/uploads\/2024\/05\/Tg-Bestimmung-Diagramm-768x390.png\" class=\"attachment-medium_large size-medium_large wp-image-11582\" alt=\"Diagram Tg value measurement curves\" srcset=\"https:\/\/www.ksg-pcb.com\/wp-content\/uploads\/2024\/05\/Tg-Bestimmung-Diagramm-768x390.png 768w, https:\/\/www.ksg-pcb.com\/wp-content\/uploads\/2024\/05\/Tg-Bestimmung-Diagramm-300x152.png 300w, https:\/\/www.ksg-pcb.com\/wp-content\/uploads\/2024\/05\/Tg-Bestimmung-Diagramm.png 982w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Measurement curves with evaluations for determining the glass transition temperature<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\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-d468cfd e-flex e-con-boxed e-con e-child\" data-id=\"d468cfd\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-06f9597 elementor-icon-list--layout-traditional elementor-list-item-link-full_width elementor-widget elementor-widget-icon-list\" data-id=\"06f9597\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"icon-list.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<ul class=\"elementor-icon-list-items\">\n\t\t\t\t\t\t\t<li class=\"elementor-icon-list-item\">\n\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-icon-list-icon\">\n\t\t\t\t\t\t\t<i aria-hidden=\"true\" class=\"fas fa-check\"><\/i>\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-icon-list-text\">Tg (DMA) &gt; Tg (DSC) &gt; Tg (TMA)<\/span>\n\t\t\t\t\t\t\t\t\t<\/li>\n\t\t\t\t\t\t\t\t<li class=\"elementor-icon-list-item\">\n\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-icon-list-icon\">\n\t\t\t\t\t\t\t<i aria-hidden=\"true\" class=\"fas fa-check\"><\/i>\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-icon-list-text\">Guide value: Tg (TMA) = Tg (DSC) -
