A kind of PCB circuit short circuit method and PCB

Abstract

The application discloses a method for shorting a PCB circuit and a PCB. The method includes: setting pads on the surface of the PCB according to the circuit design to be connected to the target circuit. The target circuit is a circuit that needs to be shorted. The pads are isolated from each other; the surface of the PCB is covered with a template with a mesh. The mesh can expose the pads corresponding to the short-circuit group. The short-circuit group consists of the target lines that need to be short-circuited together. Composition; print solder paste on the template so that the solder paste contacts the pads corresponding to the short circuit group through the mesh, and connect the pads corresponding to the short circuit group together through the solder paste; connect the short circuit through the reflow process The target lines in the connection group are short-circuited with solder paste and pads. The above-mentioned technical solution disclosed in the present application utilizes pads and solder paste to realize short-circuiting of target circuits, so as to reduce the complexity and cost of PCB circuit short-circuiting, and improve the quality of the final prepared PCB.

Description

technical field [0001] The present application relates to the technical field of PCB, and more specifically, relates to a PCB circuit short-circuiting method and a PCB. Background technique [0002] With the rapid development of electronic products, the hardware logic design of electronic products is becoming more and more complex. In order to reduce product categories and complexity, and reduce post-operation and maintenance costs, jumper Pins and jumper caps are often applied to PCB design at present. Realize line short circuit, so as to realize function switching and line isolation. [0003] In the PCB, the motherboard jumper is a manual switch on the motherboard. Connecting different jumper pins through the jumper cap can change the circuit of the motherboard to achieve different purposes, such as determining the voltage of the motherboard and the master-slave relationship of the driver. Among them, the jumper is basically composed of two parts, one part is fixed on the...

AI Technical Summary

Problems solved by technology

In the above implementation process, due to the need to set through holes on the PCB and additionally use wave soldering to solder materials, there are problems of complicated preparation process and high preparation cost, and manual installation of jumper caps will cause wrong assembly. and / or the possibility of missing packaging, which will reduce the quality of the PCB
