I don't whether it can be done on older ORCAD layout (>v9) or EAGLE.ġ) First make available all the Decal of all the parts needed on PCB that are required for Reverse Engineering.Ģ) Place all the components and add all visible Vias from component Top) side.ģ) FLIP the board layout using menu command.Ĥ) Manually routes all the pins, pads and Vias by looking at the back of PCB (now in front after flipping) and using earlier PCB that needs to be reverse engineering as a guideline.ĥ) FLIP the completed board layout once again using menu command.ħ) Rearrange the circuit blocks on OrCAD, manually.Ĩ) Go back to PADs PCB and optimized PCB layout using circuit flow. I used to do the same with PADsPCB DOS versions long time ago but on its Window version, it missed many nets, tracks and vias. I wanted to flip PCB design where only components are place on top side while routing is to be done from back-side by looking at already made PCB for reverse engineering in PADs, ORCAD and EAGLE software.
