Reverse Engineering PCB by Protel 99se

Most electronic devices today are built on Printed Circuit Boards (PCBs), which consist of multiple layers of electrical copper and insulating material sandwiched together. for this reason, Reverse Engineering PCB because one of the most popular technique for technology upgrade and advancement.
Several Electronic Design Applications (EDA) exist to both create schematics and layout drawing of a circuit from a working PCB physical sample.

We have access to Protel 99SE for these functions. The resulting PCB design from reverse engineering can then be sent to a company for a professional board manufacturing with silkscreens, multiple layers, etc. MIL also has
the ability, through a T-Tech Quick Circuit, to make single and double sided circuit boards PCBs out of copper-plated sheets of insulating material. The latter process is unable to make complicated designs, but it both quick and cheap. This tutorial covers the creation of a sample design using Protel 99SE by pcb reverse engineering technique, and its preparation to be milled out by the T-Tech.

First we must create an overall database that will contain all the individual components of the design – the Schematics that describe the circuit, the process of Reverse Engineering PCB that physically layout the components and their connections, and other assorted files.
H Start Protel and select File/New. Use a MS Access Database and give it a name – this will create a Design Database file (extension .DDB) that contains all the parts of your
design. In this case, we’ll call it Tutorial.DDB. Maximize the window – it makes it easier to have one title bar.
H The Database has its own internal File System – go into the Documents Folder, select File/New and create a new Schematic Document. Always rename your files to something more descriptive (HC11 IO.sch, Power Regulation.sch, etc.) – this will make it easier to keep track of what information is in each document. We’ll stick to the pattern and call it Tutorial.sch.
H Save often – both Windows and Protel can be buggy at times, and the last thing you
want to do is lose over an hours work because of a crash.
