After PCB has been pressed and baked, the Tg values of the samples can be measured twice by the same method and the same machine. If the Tg of Tg 2 to Tg 1 exceeds 2 ~ 3\u00b0C (Hardening including polymerization and cross-linking), the hardening reaction (including cross-linking) of the hardening process is not in the hardening position.

If the measured value is more than 5\u00b0C below the specification value, it indicates that the problem plate has water absorption lesions. The moisture in the resin acts as a plasticizer, which will not only lower Tg, but also make the rubber state arrive earlier.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-56ad7d31 elementor-widget elementor-widget-heading\" data-id=\"56ad7d31\" 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<h2 class=\"elementor-heading-title elementor-size-default\">\uc811\uc2dc\uc758 \uad6c\uba4d\uc5d0 \ubb3c\uc744 \ub2f4\uc744 \uc218 \uc788\uc2b5\ub2c8\ub2e4.<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-37f1c42c elementor-widget elementor-widget-text-editor\" data-id=\"37f1c42c\" 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><img decoding=\"async\" class=\"aligncenter wp-image-4455 size-full\" src=\"https:\/\/www.mainpcba.com\/wp-content\/uploads\/2023\/01\/holes-in-the-plate.jpg\" alt=\"\ud640 \uc778 \ub354 \ud50c\ub808\uc774\ud2b8\" width=\"1000\" height=\"750\" srcset=\"\/\/www.mainpcba.com\/wp-content\/uploads\/2023\/01\/holes-in-the-plate.jpg 1000w, \/\/www.mainpcba.com\/wp-content\/uploads\/2023\/01\/holes-in-the-plate-300x225.jpg 300w, \/\/www.mainpcba.com\/wp-content\/uploads\/2023\/01\/holes-in-the-plate-768x576.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p><p>\ubb3c\uc740 PCB \ud31d\ucf58 \ud6a8\uacfc\uc758 \uc8fc\uc694 \uc6d0\uc778\uc774\uae30 \ub54c\ubb38\uc5d0 PCB\uc758 \ubb3c \uc81c\uac70\uac00 PCB \ud31d\ucf58 \ud6a8\uacfc\uc758 \ub300\ubd80\ubd84\uc758 \ubb38\uc81c\ub97c \ud574\uacb0\ud560 \uc218 \uc788\uc5b4\uc57c\ud558\uba70 \ubca0\uc774\ud0b9\uc740 PCB \uc678\ubd80 \ubb3c\uc744 \uc81c\uac70\ud558\ub294 \uac00\uc7a5 \uc88b\uc740 \ubc29\ubc95\uc785\ub2c8\ub2e4. \ubca0\uc774\ud0b9\uc758 \ubaa9\uc801\uc740 \uc218\ubd84\uc744 \uc81c\uac70\ud558\ub294 \uac83\uc774\ubbc0\ub85c \ubca0\uc774\ud0b9 \uc870\uac74\uc740 \ub2e4\uc74c \uc694\uad6c \uc0ac\ud56d\uc744 \ucda9\uc871\ud558\ub294 \uac83\uc774 \uac00\uc7a5 \uc88b\uc2b5\ub2c8\ub2e4:<\/p><p>\ubb3c\uc774 \uc99d\uae30\ub85c \ubcc0\ud574 \ub354 \uc27d\uac8c \ube60\uc838\ub098\uac08 \uc218 \uc788\ub3c4\ub85d \uc624\ube10 \uc628\ub3c4\ub97c 100\u00b0C(\uc624\ube10 \uc628\ub3c4\ub294 \ub2e4\ub97c \uc218 \uc788\uc73c\ubbc0\ub85c 105\u00b0C\ub97c \uad8c\uc7a5)\ub85c \uc608\uc5f4\ud569\ub2c8\ub2e4.<br \/>\ubca0\uc774\ud0b9\ud560 \ub54c\ub294 \uac01 \ubcf4\ub4dc\ub97c \ubd84\ub9ac\ud558\uc5ec \uc218\ubd84\uc774 \ub354 \uc27d\uac8c \ud718\ubc1c\ub418\ub3c4\ub85d \ud558\ub294 \uac83\uc774 \uac00\uc7a5 \uc88b\uc2b5\ub2c8\ub2e4.
