This utility model proposes a magnetic snap fastener assembly for bags with a roll-up positioning structure, comprising mutually compatible male and female snap-on parts. The male snap-on part includes a male faceplate, a male magnetic ring, and a male backplate, while the female snap-on part includes a female faceplate, a female magnetic ring, and a female backplate. The male and female snap-on posts of this magnetic snap-on assembly can penetrate through the bag shell. By stamping the male and female snap-on posts, they can be split into independent pieces and rolled up to the inner wall of the bag shell for clamping and positioning. The installation process is simple and quick, requiring no complex tools or operating steps. After being rolled up, the male and female snap-on pieces form a wedge-shaped angle with the male and female backplates, and their ends abut against the outer wall of the bag shell, increasing the bonding force between the male and female snap-on parts and the outer wall of the bag shell. The components have simple structures, no irregular shapes, are easy to process, and are convenient to assemble, which helps to reduce production costs and improve production efficiency.

The invention provides a substrate and a method of manufacturing the same. A substrate according to an implementation includes a glass core having an upper surface. The bonding roughness index Rq * k value of the upper surface of the glass core according to the following formula 1 is 3.5 nm to 150 nm; the formula 1 is Rq * k = Rq * Rku2; in the formula 1, the Rq value is the root mean square deviation (unit: nm), and the Rku value is the kurtosis. In the case of such a substrate, it is possible to realize a conductive layer having substantially uniformly improved bonding force with respect to the glass core and capable of efficiently transmitting signals even when high-frequency power is applied.

The invention provides a substrate and a method of manufacturing the same. A substrate according to an implementation includes a glass core having an upper surface. The Rs / z value of the ratio value of the roughness to the degree of asymmetry of the upper surface of the glass core according to the following formula 1 is-5 nm <-2 > to 50 nm <-2 >; in the formula 1: # imgabs0 #, the Rsk value is the asymmetry value, and the Rz value is the maximum height roughness (unit: nm). In the case of such a substrate, an electrically conductive layer can be achieved which has a substantially uniformly improved bonding force for the glass core. The conductive layer is configured so as to be capable of efficiently transmitting a signal even when high-frequency power is applied.
