Abstract

The invention provides a microwave digital apparatus and a processing method therefor for solving the structural shortcomings of a conventional microwave digital composite substrate in performing separation of a digital signal from a grounding signal. The microwave digital apparatus comprises a composite circuit board and a metal shell; a back-drilling blind hole is formed in the bottom surface of the composite circuit board; and one side, facing to the composite circuit board, of the metal shell is a smooth plane, namely, the blind hole is not formed in one side, facing to the composite circuit board, of the metal shell. The processing method for the microwave digital apparatus comprises 13 continuous steps. The microwave digital apparatus and the processing method therefor have the beneficial effects that the processing on the metal shell is avoided; the processing method is more convenient than the former structural processing method, and a lower overall processing cost, and a higher processing efficiency are realized.

Description

technical field [0001] The invention belongs to the technical field of circuit processing, and in particular relates to a microwave digital device and a processing method thereof. Background technique [0002] At present, the method of separating the digital signal and the ground signal in the composite multilayer board is mainly realized by processing the metal shell connected to the composite multilayer board. The specific method is as follows: [0003] Traditional microwave-digital composite substrates lead digital signals and ground signals to the last layer through metallized through holes, and the holes connected to digital signals are separated from the holes connected to ground signals through isolation regions. But they are all on the same plane (they are all connected to the last layer), when the board is loaded into the metal shell 8, the last layer of the board is connected to the metal shell 8, then the last layer of the board is connected to the hole of the dig...
