| Abstract: | Inside the electronics electric circuit, the totally resistance interference influences the normal work of the electric circuit greatly. In PCB electric circuit design, particularly in the PCB design of the high frequency electric circuit, it is necessary to prevent the influence of totally resistance of grounding line. The article analyzes interference form of the totally resistance, introduces the restraint function of a grouding to the totally resistance interference in electronics electric circuit, especially in high frequency electric circuit, and problems that prevent the totally resistance by a grounding. At the same time it illustrates the main form and request of grounding line in PCB plank. |
