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.
