The application provides a MEMS hydrophone and method, and relates to the technical field of MEMS hydrophones.The MEMS hydrophone comprises a base, a sound-permeable shell and an acoustic sensing assembly.The sound-permeable shell and the base form a first cavity filled with hydraulic oil;the acoustic sensing assembly is located in the first cavity and comprises a shielding cover, a printed circuit board, a flexible membrane, a transition carrier plate and a MEMS chip.The shielding cover, the printed circuit board and the flexible membrane surround to form a second cavity, and the shielding cover is provided with a communication hole communicating the first cavity and the second cavity.The MEMS chip, the transition carrier plate and the flexible membrane surround to form a third cavity filled with gas.The application realizes front hydraulic pressure transmission through the hydraulic oil in the first cavity, realizes back gas pressure compensation through compression of the third cavity by the flexible membrane, forms a cooperative pressure balance mechanism, significantly reduces the net pressure difference and the prestress borne by the MEMS chip, effectively inhibits the problems of sensitivity attenuation, linearity deterioration and frequency response drift under a deep-water high hydrostatic pressure environment, and simultaneously improves the structural safety and long-term reliability.

The application discloses a kind of based on substructure pre-stabilization ultra-high multilayer printed circuit board manufacturing method, suitable for the number of layers N greater than 20 ultra-high multilayer board manufacturing.The method divides the whole manufacturing process into three stages, and sequentially forms inner core, intermediate and final substructure.The core is: after each manufacturing stage is completed, the complete encapsulation process of metalization, resin filling, grinding and copper cap plating of interconnection hole is carried out, so that the mechanical and electrical stability of the current substructure is realized before entering the next stage of pressing.Meanwhile, for each substructure, its pressing process parameters are independently set to match its material and structural characteristics.The application effectively solves the core problems of poor interlayer alignment accuracy, poor high aspect ratio hole plating uniformity and low overall yield caused by thermal-mechanical stress accumulation in traditional manufacturing of ultra-high multilayer board, significantly improves the reliability and manufacturing efficiency of the product.

The invention relates to the field of plastic product production equipment, and particularly discloses an efficient vacuum exhaust system based on split-flow feeding in a double-step plastic extruder, comprising: a base provided with a feeding cylinder; the fluid compression cavity is provided with a feeding port and a discharging port, and the feeding port is connected with the feeding cylinder and used for stacking molten plastic; the feeding barrel is fixed to the machine base and connected with the fluid compression cavity, a plurality of flow dividing holes and a plurality of vacuum holes are formed in the feeding barrel, and the flow dividing holes are connected with the discharging opening and used for dividing molten plastic in the fluid compression cavity; the screw rod is rotationally arranged in the inner cavity of the feeding barrel in a sealing manner and is used for rightward conveying the shunted molten plastic to the extrusion die head; the vacuum bins with the filtering function are fixed to the feeding barrel and communicated with the corresponding vacuum holes, and the feeding barrel, the fluid compression cavity and the feeding barrel are vacuumized and exhausted in cooperation with a vacuum pump. The exhaust efficiency is high, exhausted gas can be directly filtered and exhausted, and the environment-friendly requirement is met.

The application discloses a cooling liquid intelligent filling system for a new energy excavator, which comprises a cooling liquid tank, an electromagnetic water valve arranged on a water outlet pipeline of the cooling liquid tank, a power line plug and a controller line plug reserved for the electromagnetic water valve, and a water pump arranged in a cooling liquid circulating system of the excavator. Before the excavator is filled with the cooling liquid, the power line plug and the controller line plug of the electromagnetic water valve are inserted into the excavator, the whole vehicle supplies power to the electromagnetic water valve, and the whole vehicle controller controls the opening degree of the electromagnetic water valve through the controller line plug. The filling mode is selected through a vehicle-mounted instrument, a corresponding control program is executed by the controller, the rotating speed of the water pump in the cooling liquid circulating system of the excavator is controlled, and then the cooling liquid is controlled to flow in the cooling liquid circulating system. The application can automatically fill the cooling liquid, saves the labor cost of manual filling, can automatically circulate the filling of the cooling liquid and effectively discharge air bubbles, and prevents the heat dissipation effect from being reduced and the pipeline from being blocked due to the air bubbles in the pipeline.
