Abstract

The invention discloses a high-power routing structure based on PCB copper foil. The high-power routing structure comprises a PCB which comprises a first routing layer and a second routing layer. The first routing layer and the second routing layer are respectively provided with a plurality of electronic circuits and a plurality of wires connected with the electronic circuits. The first routing layer is connected with the second routing layer through a through hole. The wire for connecting a power circuit and a horn control circuit is a first wire with the width ranging from 5.5mm to 6.5mm. The first wire is obtained by removing a solder resist layer and directly exposing the copper foil. The first wire is covered with a soldering tin layer. The wiring harness of a finished vehicle can be simplified, the fault can be accurately and conveniently detected and checked, and the effect on other vehicle electric appliances from the circuit disturbance when a high-power vehicle electric appliance works is reduced.

Description

technical field [0001] The invention relates to an automobile controller, in particular to a high-power routing structure based on PCB copper foil. Background technique [0002] Traditional high-power automotive electrical appliances are controlled by wiring harnesses, insurance and switches. This traditional method not only has many wiring harnesses, but it is difficult to accurately troubleshoot faults, and when high-power automotive electrical appliances are working, it is likely to generate a lot of disturbances on the circuit through the wiring harness conduction or radiation to affect the normal operation of other automotive electrical appliances. [0003] In today's increasingly integrated, intelligent and humanized automotive electronics field, as well as the reality that users' requirements for automotive comfort are increasing, the control of traditional high-power automotive electrical appliances in the car is increasingly unable to meet the needs of automotive el...
