PCB Reverse Engineering: Everything You Need To Know


When it comes to working with Printed Circuit Boards (PCBs), reverse engineering is a prominent method used by many companies. Using PCB reverse engineering, you may gather critical knowledge about their functionality and design, minimize printed circuit board repair price, update outdated computer chips, or build a less expensive alternative to a competitor. A thorough grasp of how your PCBs function may be gained by learning to reverse engineer them.

What Is “Reverse Engineering” a PCB?”

In May 2021, the PCB industry saw a 9.1% growth in revenue, indicating an increasing demand for PCB boards in the sector. PCB reverse engineering is a multi-step procedure that entails conducting PCB research, performing reverse analysis, and reproducing PCB design technology.

A product’s functional and structural features, as well as its processing flow, may also be determined through this procedure. A corporation can then use this knowledge to develop solutions with similar capabilities.

Product design concepts are the primary objective of reverse engineering. It’s essential when a business has difficulty accessing design information for a particular product. A PCB sample is disassembled and analyzed to do reverse engineering on it.

Based on this research, a corporation will generate documentation describing the prototype PCB, which other team members may evaluate. It is common for this paperwork to provide details regarding the product’s design and operation.

Companies then use sample PCBs to help them design and build comparable products that may perform better than their competitors. Moreover, reverse engineering may assist firms in enhancing their PCB offerings and analyzing and outdoing rivals’ goods.

Also, Oscillators is one of the important component in PCB that have a highly stable frequency.

What Are the Advantages of Reverse Engineering a Circuit Board?

Maintaining Critical PCBs

There are occasions when a piece of equipment or an electrical component requires an obsolete PCB. You may not obtain a new PCB or know how to fix it if the PCB malfunctions or has to be replaced.

Both of these instances can benefit from reverse-engineering the old PCB, which allows you to keep critical PCBs for a long time and perhaps clone them when repairs aren’t possible.

Find Out About PCBs Without Looking at Documentation

Documentation or CAD data is often included with modern PCBs. There are instances when PCBs are unable to access any information. Recognizing the PCB’s schematic and design through reverse engineering is critical in this situation.

Thanks to reverse engineering, it is possible to build your documentation on the product, which will help you understand how to fix or duplicate it.

Reduce Your Dependence on Professionals

One of the first things you’ll likely do if your PCB is experiencing a problem is to seek the assistance of a professional. There are situations when there are no experts who can manage your PCB.

You may find yourself in a difficult situation if you lack PCB expertise. By employing reverse engineering, you may learn a great deal about your PCB and identify potential trouble spots without the assistance of an expert.

Produce PCBs at a Lower Cost

Reverse engineering a competitor’s high-priced PCB allows you to discover how much the product truly costs to make. Often, PCBs are sold at a greater price since there is less competition. It is possible to build a similar PCB at a lower cost and thereby attract more customers who previously had no other choice than to pay the higher price.

How Do You Reverse Engineer a PC Board?

Scan The Board

Drawing, scanning, or photographing a PCB is the initial step towards reverse-engineering it. Be sure to photograph the PCB from all sides if you do so. Also, be sure you capture it against a dark background.

There should be no backdrop visible through any PCB holes, as this might give the impression that the PCB is made of copper. The PCB’s structure may be seen thanks to a dark background.

Place the Image in Your Document

Uploading the photos to your reverse engineering software is as simple as taking them. Crop the image so that it just depicts the PCB before uploading it. You may edit images and scans with a range of online tools, and you can also use PCB capabilities.

Make a Plan for Your Design

You’ll need to create a 3D layout of the PCB after uploading your photos to your selected reverse-engineering PCB application. Electromagnetic field dispersion and circuit behavior are depicted in a PCB’s layout. Parts that can’t be described in schematics, like components, conductor elements, and trace layout, are also depicted in this figure.

Generate Models

The schematic for the PCB is the next phase. The schematic diagram of a PCB allows you to examine every circuit and every component on the board. A 2D CAD assembly design is commonly used to depict the schematic.

Engineers can explore how different components are connected and what their functions are by using this 2D depiction of the schematics. If you’re attempting to repair or recreate a PCB, you’ll need all of this information.

Reverse engineering PCBs may be a complicated task, and you may seek help from PCB professionals.
