Embodiment 1

[0028] This embodiment provides a method for manufacturing a printed circuit board for a signal generator, and the specific process is as follows:

[0029] (1) Cutting: cut out the core board according to the board size 520mm×620mm, the thickness of the core board is 0.8mm, and the thickness of the outer layer of copper foil is 1OZ.

[0030] (2) Inner layer circuit production (negative film process): Inner layer graphics transfer, use a vertical coating machine to coat a photosensitive film on the core board, the film thickness of the photosensitive film is controlled at 8 μm, and a fully automatic exposure machine is used to 5-6 grids The exposure ruler (21-grid exposure ruler) completes the exposure of the inner layer circuit on the core board; the inner layer is etched, and the inner layer circuit is etched out of the exposed and developed core board. Include the earthworm wire 1 (such as figure 1 shown); the inner layer AOI, and then check the open and short circuits, lin...

Abstract

The invention discloses a manufacturing method of a printed circuit board for a signal generator, and the method comprises the following steps: manufacturing an inner-layer circuit on a core board, wherein a plurality of continuously bent U-shaped earthworm wires are inclined in the inner-layer circuit manufactured on one surface of the core board; pressing the core board and outer-layer copper foil into a production board through a prepreg; drilling holes at the positions, corresponding to the end parts of the earthworm lines, of the production board; metalizing the holes through copper deposition and full-board electroplating; and sequentially manufacturing an outer-layer circuit, manufacturing a solder mask layer, and carrying out surface treatment and forming on the production board toobtain the printed circuit board. The printed circuit board manufactured by the method provided by the invention can effectively reduce the loss of line signals and ensure the transmitting and receiving conversion efficiency of an antenna.

Description

technical field [0001] The invention relates to the technical field of manufacturing printed circuit boards, in particular to a method for manufacturing a printed circuit board used in a signal generator. Background technique [0002] A signal generator, also known as a signal source or an oscillator, is a device that can provide various frequencies, waveforms and output electrical signals. It is used to measure the amplitude characteristics, frequency characteristics, transmission characteristics and other electrical parameters of various telecommunication systems or telecommunication equipment. When measuring the characteristics and parameters of components, it is used as a test signal source or excitation source, which has a wide range of applications in production practice and technology. [0003] Printed circuit board, referred to as PCB (Printed Circuit Board), is an important electronic component, a support for electronic components, and a provider of electrical conne...
