They are made by bonding a layer of copper directly onto a ceramic substrate, typically aluminum oxide or aluminum nitride. Due to the DBC technology is directly bond copper on the ceramic substrate, it can achieve thicker copper thickness to 300um. So, it is very suitable for high power applications.<\/p>\n\n\n\n<p>The basic chemistry principle is to introduce an appropriate amount of oxygen between copper and ceramics before or during the application process. Copper and oxygen will form Cu-O eutectic liquid under 1065\u2103~1083\u2103. This is an important element in the manufacturing. <a href=\"https:\/\/www.bestpcbs.com\/products\/DCB-ceramic-pcb.htm\" title=\"\">DBC ceramic circuit board<\/a> uses this eutectic solution to chemically react with the ceramic substrate to form CuAlO2 or CuAl2O4, achieving the combination between substrate and copper foil.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2024\/07\/DBC_ceramic_pcb.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"600\" src=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2024\/07\/DBC_ceramic_pcb.jpg\" alt=\"What are the different types of ceramic pcbs?\" class=\"wp-image-1834\" srcset=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2024\/07\/DBC_ceramic_pcb.jpg 600w, https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2024\/07\/DBC_ceramic_pcb-300x300.jpg 300w, https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2024\/07\/DBC_ceramic_pcb-150x150.jpg 150w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/a><\/figure>\n\n\n\n<p>However, it is easy to generate micro-porosity between Al2O3 and Copper during the copper bonded process, and it doesn\u2019t have a good solution by far.
