Printed Circuit Board Clone Inspection

After Printed Circuit Board Clone process done, engineer need to inspect the work done, as we all know, electrical characteristic of Printed Circuit Board is always the most critical aspects, so below items refers to its electrical characteristic must be inspected one by one:

1. If the track’s resistance, inductance, capacitance effect have been taken into consideration?

2. the distance and shape among tracks are all comply with isolation requirement?

3. in those critical places of Printed Circuit Board schematic diagram if the isolation resistance value has been controlled and regulated?

4. if all the footprint of electronic component info from Printed Circuit Board reverse engineering has been fully identified?

5. measure the track space from the perspective of geometry against the resistance and voltage?

6. the alteration of medium of surface coating has been certified or validated?

And there are also some physical features of PCB Assembly reverse engineering need to inspect:

1. all the solder pads and their locations to see if all of them are properly installed;

2. if the fully assembled Printed Circuit Board can withstand the vibration and shock;

3. is there sufficient space among the standard components?

4. all those components with heavy weight are all properly located and installed;

5. all the heating component can be thermal dissipation properly? And are they being separated with other thermal sensitivity components?

6. those components with potentiometer or multiple leads are all properly located;

7. components installation and orientation are all convenient for inspection;

8. all the interference on the Printed Circuit Board and on the components are all eliminated?

9. Alignment holes are all properly designed?

10. If all the tolerance is complete and reasonable;

11. all the tracks and lead diameter ratio are within the acceptable range?

Strength the ability of PCB Card cloning:

After the circuit board reverse engineering rule has been confirmed, reverse engineering engineer switch to the physical realization of Printed circuit board. The general circuit board drawing tool can provide comprehensive component selection ability, which can install the circuit board layer count, dissipation and restriction principle and manage the location of all the components on the circuit board. A outstanding tool must be easy to use and can manage all the terms then restrict the circuit board reverse engineering automatically and consequently come out the Printed circuit board clone.
