What is the IT-150DATC PCB Material?
IT-150DATC is a high Tg (180° C by DSC), advanced multifunctional epoxy and low loss material. This material has low Dk and low Df performance. It is commonly used in electronic devices and systems where high temperatures and demanding operating conditions are present. The acronym “TG” refers to the glass transition temperature, which is the temperature at which the material changes from a rigid, glassy state to a softer, rubbery state. High TG materials have a higher glass transition temperature, typically above 180°C, which means they can withstand higher temperatures without undergoing significant dimensional changes or losing mechanical integrity.
The IT-150DATC substrate is known for its excellent thermal stability and low coefficient of thermal expansion (CTE). These properties make it highly suitable for applications that involve high-power components, such as power electronics, automotive electronics, and industrial equipment, where heat dissipation and reliability are critical. The IT-150DATC substrate is typically made from a composite material that consists of a high-quality epoxy resin reinforced with glass fibers. This combination provides the substrate with excellent mechanical strength, dimensional stability, and resistance to thermal stress. IT-150DATC is designed not only for standard multilayer PCB, but also for radar application. This material is also suitable for 3S (Server/Storage/Switch) application.
