Reverse Engineering Printed Circuit Board from OrCAD

When Reverse Engineering Printed Circuit Board design of a two layer PCB using the OrCAD Layout and the Capture family of programs. OrCAD version 10.1 was used for this tutorial. In addition, Reverse Engineering Printed Circuit Board procedures contains procedural details for in-house processing. A detailed description of the Printed Circuit Board fabrication process using photo development, and etching of the copper clad board is included.

Although PCB Board cloning may generally be useful for all undergraduate students of electrical engineering, it is specifically designed and written for the students in the Communications Systems Design courses.

The first step in the circuit card cloning is to familiarize yourself with the OrCAD family of products, particularly OrCAD Capture which is used to draw the schematic diagram, and also OrCAD Layout which is used for the actual layout design of the PCB.

The simulation process of PCBA Clone using PSPICE will not be mentioned since it does not directly relate to PCB design, however It may be important to familiarize yourself with it’s functions incase a design is to be simulated before it is built on a hardware level.

If possible, it is recommended that the design is prototyped by construction on a breadboard and the fnctionality tested. Once the circuit is made on PCB it is very hard to troubleshoot and change. With this said, it is understood that in high frequency designs, Reverse Engineering PCB is not possible. Therefore several trials of PCB prototypes may have to be designed and fabricated in to have a fully functional circuit or system.

We would like to point out that being able to fabricate your own PCBs in-house at the Microelectronics Research Laboratory (MERL) is a very valuable task which is rather inexpensive and has a very fast turnaround time.
