Automotive Window Electronic Switch PCB Board Cloning

Automotive Window Electronic Switch PCB Board Cloning will include Simulation Analysis and Improvement of PCB Electromagnetic Compatibility of Automotive Window Electronic Switch.

Taking the PCB of the automotive window electronic switch system as an example, the method of combining software Protel 99SE and Ansoft Designer is used to simulate and analyze the electromagnetic field of the PCB board after redraw the circuitry pattern and then generate gerber file from physical printed circuit board sample.

And its electromagnetic compatibility in the early reverse design stage. The flowchart is shown in below Figure,

First restore the circuit schematic diagram of the car window electronic switch PCB Board system, and draw its schematic diagram in Protel 99SE according to the circuit diagram.

This article takes a certain kind of car window electronic switch system as an example for simulation. Its working principle is: the left front window is the main switch, and the right front, left rear and right rear switches are controlled by the relay K3.

Among them, the left rear and right rear are mechanical switches that need to be manually pushed to realize the switch on and off. When the switch is turned on or off, the generated switching signal is rectified and operationally amplified and then input to the PIC microcontroller to generate an output control signal.

The function of controlling the large current with a small current through the relay can realize the action of controlling the window.
