Example Embodiment
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] see figure 1 . According to the present invention, after the fabrication steps are determined, the determination of the process parameters is the key to ensure the fabrication of the closed cavity, and the main influencing factors are: alignment accuracy, lamination pressure, lamination temperature, filling density, and sintering temperature. The low-temperature sintered ceramic powder is made into a green ceramic tape with precise and dense thickness, and the required circuit patterns and wiring patterns are produced on the green ceramic tape by punching, micro-hole grouting, and precision conductor paste printing. Passive components, such as low-capacitance capacitors, resistors, filters, impedance converters, couplers, etc., are embedded in a multi-layer ceramic substrate, then stacked together and sintered at 900 °C to make high-density non-...
