Ageing-resistant and impact-resistant AMB silicon nitride ceramic copper-coated sheet and preparation method thereof
The invention discloses an anti-aging and anti-impact AMB silicon nitride ceramic copper-clad sheet and a preparation method thereof. The anti-aging and anti-impact AMB silicon nitride ceramic copper-clad sheet is prepared from a ceramic substrate, a first metal foil, a second metal foil, a nano metal layer and a copper-clad sheet, the first metal foil is a copper foil or a first alloy foil, and the second metal foil is a titanium foil or a second alloy foil; the nano metal organic solution is smeared on the inner surface of the copper-clad sheet, a nano metal layer is formed after drying, the two faces of the first metal foil, the two faces of the second metal foil and the two faces of the ceramic substrate are sequentially attached from outside to inside, welding is conducted, and the anti-aging and anti-impact AMB silicon nitride ceramic copper-clad sheet is obtained. According to the AMB ceramic copper-clad sheet manufactured through the method, the bonding strength, the aging resistance and the cold and hot impact resistance all exceed those of an AMB ceramic copper-clad sheet product manufactured through traditional silver-copper-titanium soldering paste, the overall performance level is advanced, the process is simple, the cost is low, and the AMB ceramic copper-clad sheet is suitable for industrial popularization.
本申请公开了一种耐老化抗冲击的AMB氮化硅陶瓷覆铜片及其制备方法，由陶瓷基片、第一金属箔片、第二金属箔片、纳米金属层和覆铜片制备而成；所述第一金属箔片为铜箔或第一合金箔片，所述第二金属箔片为钛箔或第二合金箔片；所述覆铜片的内表面涂抹所述纳米金属有机溶液，烘干后形成纳米金属层，从外向内依次将所述第一金属箔片、第二金属箔片和陶瓷基片的两个面贴合，焊接得到所述耐老化抗冲击的AMB氮化硅陶瓷覆铜片。本申请的方法制作出来的AMB陶瓷覆铜片结合强度、耐老化性能和耐冷热冲击性能都超出了传统银铜钛焊膏制作的AMB陶瓷覆铜片产品水准，在整体性能水平上有先进性，并且工艺简单成本低，适于工业化推广。
