The application provides a packaging substrate and a processing method thereof. The packaging substrate comprises a ceramic substrate, a first build-up structure and a second build-up structure. The ceramic substrate comprises a ceramic plate member having a conductive hole penetrating through the ceramic plate member along the thickness direction of the ceramic plate member, a conductive column is arranged in the conductive hole, one side of the ceramic plate member in the thickness direction is provided with a first conductive layer, and the first conductive layer is electrically connected with one end of the conductive column. The first build-up structure is arranged on the side of the first conductive layer away from the ceramic plate member, the first build-up structure is electrically connected with the first conductive layer, the first build-up structure is formed by an RDL process, and the first build-up structure is used for electrical connection with a chip. The second build-up structure is arranged on the other side of the ceramic plate member in the thickness direction, the second build-up structure is electrically connected with the conductive column, the second build-up structure is formed by an MSAP process, and the second build-up structure is used for electrical connection with a PCB. The packaging substrate of the embodiment of the application has high flatness and can meet the demand of interconnection with a chip with a smaller spacing on the basis of being connected with the PCB.

The utility model relates to a kind of multifunctional combination flute, including playing section, membrane hole section and finger hole section, playing section, membrane hole section and finger hole section all include at least two kinds;Playing section, membrane hole section and finger hole section can be combined according to the requirement of playing through cannula and inner sleeve pipe insertion connection.The multifunctional combination flute of the utility model, playing section, membrane hole section and finger hole section can include at least two kinds, when playing, user can flexibly assemble according to the need of playing, assemble into at least 8 flutes, in this way, the number of flute carried can be greatly reduced, and the function of flute is expanded.By the way of cannula and inner sleeve pipe insertion connection, the air tightness of connecting part can be guaranteed, and the tone of flute is guaranteed.By setting reinforcing sleeve ring on the outer wall of connecting part, the end surface of connecting part can be protected, preventing deformation or cracking of flute pipe, and prolonging its service life.

The utility model relates to a toy clarinet capable of automatically tuning the height, which comprises a clarinet head, a clarinet body and a tuning component, the tuning component comprises a limit window frame and at least one tuning foot, the limit window frame is detachably arranged in a clarinet window of the clarinet head, and the tuning component is formed on the inner wall of the limit window frame and extends into a sound hole in the clarinet window. And the tuning pin passes through the air passage and is transversely arranged on one side, close to the sound outlet hole, of the blowing hole to partially block the blowing hole. According to the technical scheme, in the playing and playing process of a child, when the child puts the lip close to the blowing hole of the flute head to blow air and air flow passes through the air channel at the intersection of the blowing hole and the sound outlet hole, the flow speed of the air flow is increased under the effect of the tuning foot of the tuning component, so that the pitch is changed, and the change of the pitch can be realized through the structure of the toy flute; the high interestingness is provided for children during playing, and the playing pitch is adjusted on the premise that the playing mode of the children is not changed, so that the pitch is kept within the range that the children feel comfortable.
