Embodiment Construction

[0044] The following is attached Figure 1-3 The application is described in further detail.

[0045] The embodiment of the present application discloses a method for designing a radio frequency circuit layer structure. refer to figure 1 , a method for designing a radio frequency circuit layer structure, comprising the following steps:

[0046] S1. Component layout.

[0047] Wherein, the components are arranged in the same direction on the circuit board. Specifically, the general principle of layout is that the components should be arranged in the same direction as possible, and the phenomenon of poor soldering can be reduced or even avoided by selecting the direction in which the PCB enters the tin melting system.

[0048] In addition, there is at least 0.5mm spacing between the components to meet the tin melting requirements of the components. If the space of the PCB board allows, the spacing of the components should be set to be greater than 0.5mm.

[0049] refer to ...

Description

technical field [0001] The present application relates to the technical field of wireless radio frequency circuit technology, in particular to a design method of a radio frequency circuit layer structure. Background technique [0002] Radio frequency is a non-contact automatic identification technology that emerged in the 1990s. Compared with traditional magnetic card and IC card technology, radio frequency technology has the characteristics of non-contact, fast reading speed, and no wear and tear. Wireless radio frequency technology performs non-contact two-way data transmission between the reader and the radio frequency card to achieve the purpose of target identification and data exchange. [0003] In the current application of wireless radio frequency circuit technology, the performance index of the radio frequency circuit directly affects the quality of the entire product. The anti-interference design of the printed circuit board (PCB) of the radio frequency circuit c...
