LTCC power inductor matrix and non-magnetic ferrite material matched co-firing method and inductor
The invention discloses an LTCC power inductor matrix and non-magnetic ferrite material matched co-firing method. According to the method, a low-temperature sintered NiCuZn ferrite material and a non-magnetic ferrite material are subjected to matched co-firing through an LTCC wet tape casting process. According to the invention, the matching of NiCuZn ferrite and a non-magnetic ferrite material isrealized by using an LTCC process; wherein the non-magnetic ferrite layer is used as a non-magnetic air gap to adjust the magnetic performance of the whole co-fired body and the electrical performance of an element, so that the laminated co-fired body which can be sintered at a low temperature of 900 DEG C, is free of layering and cracking, is free of deformation and is good in combination is obtained; and the direct-current characteristic of the laminated power inductor manufactured by taking the co-fired body as a base material is superior to that of a non-magnetic air gap inductor.
本发明公开一种LTCC功率电感基体与非磁性铁氧体材料匹配共烧方法，该方法为由低温烧结NiCuZn铁氧体材料和非磁性铁氧体材料通过LTCC湿法流延工艺进行匹配共烧。本发明应用LTCC工艺实现NiCuZn铁氧体与非磁性铁氧体材料匹配，其中将非磁性铁氧体层作为非磁性气隙调节整个共烧体的磁性能和元件的电性能，得到一种能在低温900℃烧结，无分层开裂，无变形且结合良好的叠层共烧体；并且以该共烧体为基体材料制作的叠层功率电感的直流特性优于无非磁性气隙电感。
