Cloning Electronic Circuit Board
Cloning Electronic circuit board will refers to the mixed signals issue, especially for the current electronic consuming products, most of them have the mixed signals on the separated area after Electronic circuit board cloning and PCB designer should be aware of this point. As we all know, Electronic circuit board with mixed signal circuit which include digital circuit and analog circuit could be extremely complicate compare with other Electronic circuit board cloning. The electronic component arrangement, PCB layout as well as the power supply and grounding line treatment can directly affect the electrical performance and electro-magnetic performance after cloning Electronic circuit board. So the engineers will sufficient experience can optimize the mixed signal Electronic circuit board cloning and design features through the separation of ground and power supply circuit.
If engineers have suspect on the design unique grounding for Electronic circuit board with mixed signals, the way to cut off the grounding layer to adjust the Electronic circuit board layout before Cloning Electronic circuit board, but in the process of Cloning Electronic circuit board, engineer should pay sufficient attention on layout of Electronic circuit board to ensure the board can be connected by a jump with less than 0.5 inch length or 0 OHM resistor. And make sure the engineer can tell the separated areas and layout, to ensure no digital signal line above the analog part or any analog signal line above any digital part. However, any one of signal lines can’t cross the space among grounding or cut off the space between power supply grounds when Cloning Electronic circuit board. If it is necessary to test the Electronic circuit board functionality and Electronic Magnetic Cross features, and connect two grounds through 0 OHM resistor or jump together after printed circuit board clone, recheck the Electronic circuit board functionality and Electronic Magnetic Cross features. Compare the test result, it will come out that almost in all of the situations, united grounds solution could be more advanced than separated grounds in the aspect of Electronic Magnetic Cross features.
