Silicon nitride ceramic copper-clad substrate and preparation method thereof
The invention discloses a silicon nitride ceramic copper-clad substrate and a preparation method thereof, and belongs to the technical field of ceramic substrates. The ceramic substrate comprises a ceramic plate and a copper sheet, and the copper sheet covers the surface of the ceramic substrate. The ceramic plate comprises the following components: silicon nitride, yttrium oxide, zirconium oxide, magnesium oxide, a binder, a dispersing agent, a defoaming agent and chopped alumina fibers. And placing the pre-oxidized copper sheet on a ceramic plate formed by pressing, sintering, and cooling to obtain the silicon nitride ceramic copper-clad substrate. The prepared silicon nitride ceramic copper-clad substrate has excellent heat conductivity, bending strength and fracture performance, and is low in surface warping degree.
本发明公开了一种氮化硅陶瓷覆铜基板及其制备方法，属于陶瓷基板技术领域。其包括陶瓷板和铜片，所述铜片覆盖于所述陶瓷基板表面。陶瓷板包括如下组分：氮化硅、氧化钇、氧化锆、氧化镁、粘结剂、分散剂、消泡剂、短切氧化铝纤维。将预氧化的铜片置于压制成型的陶瓷板上，接着进行烧结，冷却后即得氮化硅陶瓷覆铜基板。制得的氮化硅陶瓷覆铜基板，具有优异的热导率、抗弯强度及断裂性能，且，表面翘曲度低。
