Problems solved by technology

[0002] In the design process of PCB (Printed Circuit Board, printed circuit board), the more important design point is to avoid the occurrence of isolated copper, which refers to the isolated copper in the PCB, which is not connected to the GND (Groud, grounding terminal) of the circuit. These coppers have no practical effect on the PCB, but will become a noise source. The radiated noise signal will interfere with other RF signals and affect the overall performance of the PCB.
[0003] In related technologies, although engineers will notice the above problems when designing PCBs, because PCB design needs to be constantly modified, some components may be deleted in the later stage of design, so the ground connected to the main ground only through these components it may become a lonely copper
At this time, it is more difficult and time-consuming to find the lonely copper by manual search.

Abstract

The invention provides an isolated copper detecting method and device. The method comprises the steps that a non-core component on a printed circuit board is determined; whether isolated copper is generated on the printed circuit board without the non-core component is determined; and if isolated copper is generated, a determined result is recorded. According to the embodiment, the non-core component on the PCB is determined; whether isolated copper is generated on the PCB without the non-core component is determined; a determined result is recorded; reference is provided for the PCB design; and isolated copper is prevented from being generated by the removal of one or more components in the later period of circuit design, or one or more components which are removed and cause the generation of isolated copper can be conveniently and quickly found out when isolated copper is generated.

Description

technical field [0001] The present disclosure relates to the field of circuit technology, in particular to a method and device for detecting an isolated copper. Background technique [0002] In the design process of PCB (Printed Circuit Board, printed circuit board), the more important design point is to avoid the occurrence of isolated copper, which refers to the isolated copper in the PCB, which is not connected to the GND (Groud, grounding terminal) of the circuit. These coppers have no practical effect on the PCB, but will become a noise source. The radiated noise signal will interfere with other radio frequency signals and affect the overall performance of the PCB. [0003] In related technologies, although engineers will notice the above problems when designing PCBs, because PCB design needs to be constantly modified, some components may be deleted in the later stage of design, so the ground connected to the main ground only through these components It may become a lo...
