WIPO Patent Application WO/2021/136063

Kind Code:

A1

Abstract:

A ceramic/resin composite casing body (10), comprising a ceramic component (101) and resin components (102) injection molded on the ceramic component (101); at the surface where the ceramic component (101) is bound to the resin components (102), there are a plurality of strand-shaped holes (103) extending from the ceramic surface into the inner portion of the ceramic component (101), the strand-shaped holes (103) being cavity structures, the hole diameters being within the range of 700 nm - 500 μm, the length of at least a portion of the strand-shaped holes (103) being greater than 100 μm and less than or equal to 1000 μm, and the strand-shaped holes (103) being filled with a resin material from which the resin components (102) are made. The present composite casing body (10) possesses both the texture and look of ceramic and an intricate inner structure composed of resin, and the ceramic and the resin are tightly bound and have a high binding strength. Further provided is a preparation method for the ceramic/resin composite casing body (10) and a terminal which comprises the composite casing body (10).
