Embodiment Construction

[0011] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0012] In the embodiment of the present invention, when designing the PCB, the PCB pad packages of the two pins are shorted together by default, so as to realize the default conduction of two different networks.

[0013] In the embodiment of the present invention, when designing the PCB board, a PCB pad package with two pins (Pin) default shorted (Default Short) is designed, and the first pin (Pin1) and the second pin (Pin2) are designed as Short them together to achieve default conduction.

[0014] like figure 1 As shown, the embodiment of the present invention designs a PCB pad package 100 in w...

Abstract

The invention is suitable for the design field of printed circuit board (PCB) boards and provides a short connection method and a PCB pad package for different networks. PCB pad packages of two pins are in short connection. The short connection method achieves the conduction of two different networks based on the principle design of the PCB boards, reduces design risks caused by manually covering copper foils in design of the PCB boards, achieves conduction from the principle design to have the fool-proof function, and simultaneously prevents part material cost and part paster cost from increasing due to series connection of zero ohmic resistors or magnetic beads in a traditional method.

Description

technical field [0001] The invention belongs to the field of PCB board design, and in particular relates to a short-circuit method for different networks and PCB pad packaging. Background technique [0002] In some special circuit designs, two different networks need to be shorted together. For example, in a digital-analog hybrid circuit, analog devices and digital devices need to be placed separately, and their respective grounds (analog ground, digital ground) are also independent of each other. , but in the end, it is still necessary to realize the conduction of the analog ground and the digital ground through single-point grounding or multi-point grounding to achieve the purpose of common ground and avoid mutual interference between digital and analog. [0003] When designing a printed circuit board (PCB), one of the traditional design methods is to connect two different networks in series with zero-ohm resistors or magnetic beads, but this will increase the number of pa...
