Replicate Printed Wiring Board for Component Arrangement

Replicate Printed Wiring Board for Component Arrangement which has been viewed as Bill of material, this documents can be obtained by reverse engineering pc board;

Clone PCB Card technology also include the component arrangement on it, in the process of determine Printed Wiring Board material, it is lay-up structure, dimension and functionality block system, component arrangement should be the next step to be taken into consideration, and it include place all of the electronic components onto the proper places of Printed Wiring Board. Appropriate electronic components arrangement on the Printed Wiring Board can strength its electronic magnetic compatibility which is also a necessary premise.

When layout the special components on the schematic by restoring schematic diagram of printed circuit board, below issues must be noted:

1, shorten the distance of electrical wire which connect the high frequency component, and decrease their distribution parameters and mutual electro-magnetic interference. And those components which is more tend to be interfered by electro-magnetic shouldn’t be layout too close, and output and input components shouldn’t be placed too close;

2, and some components could probably have high electrical level difference between other circuits, and their distance should be widen to avoid the short circuit accidently by static discharge or something when PCB reverse engineering software, and those components with high voltage should be placed on the area where the bare hand won’t be reachable in the process of Printed Wiring Board debugging and adjustment;

3, those components with weight over than 15kilograms should be supported by fixed bracket and then soldering it. As for those parts with heavy weight and great thermal dissipation, they are not suitable for assemble on the  it, they should be installed on the enclosure plate for the sake of heat sink issue;

4, as for these potentiometer, adjustable conductance coil and adjustable switch should consider the structure requirement of whole Printed Wiring Board. If the adjustment is made inside the enclosure, then these parts should be layout on the reachable places, even outside the Printed Wiring Board, then it should have a direct connection with the adjustable button on the enclosure.
