Active Metal Brazing (AMB) is the latest developments in ceramic substrates and offers the ability to produce Heavy Copper with a AlN (Aluminium Nitride) or SiN (Silicon Nitride). The normal metallisation process is not used as AMB involves brazing pure copper on the ceramic in a high temperature vacuum brazing process. As well as offering a high reliability substrate with unique heat dissipation. The brazing technology also enables double sided copper weights of up to 800µm on thin ceramic substrates of just 0.25mm. In general, the AMB Substrates include AMB Substrates and AlN AMB substrates.


The global AMB ceramic substrates market is dominated by a few players like Denka, Rogers Corporation, Ferrotec, BYD and Toshiba Materials due to the high technology barrier. Global three players hold a share over 80 percent in 2022.


Applications of AMB substrates include Automobile, Traction & Railway, New Energy & Power Grid, Military & Aerospace, etc. In recent years, more and more Chinese players enter the AMB ceramic substrates market, driven by the rapid growth of new energy vehicles in China market. China market for AMB ceramic substrates was valued at $ 166.4 million in 2022 to reach $ 1614 million by 2029, at a CAGR of 30.02 % during the forecast period of 2023 through 2029.  Moreover, global AMB ceramic substrates market is projected to reach US$ 2563 million by 2029 from an estimated US$ 375.7 million in 2022, at a CAGR of 26.0% during 2023 and 2029.
