在电子制作过程中,必须绘制PCB图和制印刷电路板。目前大部分PCB图绘制工作都使用PROTEL软件。对其使用已较熟练,但是由于有时对电路板的总体布线的不合理,从而导致所设计出的印刷电路板,在调试和组装过程中,会出现各种不必要的干扰和影响,严重时,会使整块印刷电路板作废。造成较大浪费。这其中主要问题可能在地线的布置方面。例如:我们自己绘制一幅功放的PCB图,并且依照这幅图制电路板,既使所采用的电路已经成熟定型,
In the electronic production process, PCB drawing and printed circuit board must be drawn. At present, most of the PCB drawing work using PROTEL software. Its use has been more skilled, but due to the overall wiring of the circuit board is sometimes unreasonable, resulting in the design of the printed circuit board, debugging and assembly process, there will be a variety of unnecessary interference and influence, serious , Will make the entire printed circuit board void. Cause greater waste. The main problem may be the layout of the ground wire. For example: We draw a PCB diagram of the power amplifier, and in accordance with this plan circuit board, even if the circuit used has been mature stereotypes,
