What is PCB reverse engineering?

PCB reverse engineering (sometimes called PCB extraction or PCB slicing) is the process of taking a physical board and reverse-engineering its components to learn about how it was made. It is commonly used to study the design and construction of a PCB so that it can be improved or debugged.

Reverse engineering pros and cons

PCB prototyping boards are different types of PCBs designed for testing and evaluation. These prototypes can be used to evaluate the performance of your design prior to starting mass production or assembly. PCB Prototype Boards include:

how to reverse engineer a circuit board?

There are three main components of a circuit board: the substrate (mostly plastic), the circuit components, and the interconnects. The substrate contains all the holes and electrical connections for the circuit board and may have very little to do with the circuit. The circuit components are the components of the board that have a specific function, such as a microcontroller. Finally, the interconnects are the connections between every component on the board that allows the circuit to function. Once you know the components, it’s easy to reverse engineer a circuit board.

Step1: Take Pictures of the Circuit Board

This may seem basic, but it’s something that a lot of reverse engineers don’t do. First of all, it may seem unimportant, but it’s actually very important. If you don’t take pictures of the board, you won’t be able to reverse engineer it. All you’ll have is samples of the board, and then you’ll have to try to piece everything together yourself. Taking pictures of the board is essential for reverse engineering, so make sure you do it.

Step2: Trace Components

Next, trace the components on the board. This may seem like common sense, but a lot of reverse engineers don’t do it. By tracing components, you can figure out what components the board has, what their specifications are, and what their prices are. You can even use a multimeter to read the traces and determine what they do.

Step3: Construct PCB Layout

Reverse engineering a PCB involves creating a 3D layout of the board. This helps to visualize the electromagnetic field distribution and how different circuits behave. Additionally, it shows other aspects of the PCB that cannot be observed in a schematic, such as components, conductive elements, trace arrangement, and planes for each layer.

Step4: Create PCB Schematics

When you derive a PCB’s schematic diagram, you can see every circuit and all of the board’s components in two dimensions. This helps an engineer understand how different components connect and what their functionalities are. All of this information is crucial when repairing or reproducing a PCB.

Step5: Assemble the Circuit Board

Now that you have a good idea of how the board is made, you can start reverse-engineering it. First, trace all of the components on the board and write down their specifications. Next, identify the board’s components, and their specifications. From there, assemble the board by putting the components on the circuit board.

PCB Reverse Engineering Cost

PCB Reverse Engineering costs are dependent on a variety of factors, such as complexity of the design, circuit characteristics, scope of the project, workload, etc. Unless the input data at the time of quotation is imperfect, or major engineering changes result in significantly longer delivery times, our quotations are fixed of. Here is a detailed breakdown of what costs you and how much it will cost you.

PCB Design Cost

Depending on your PCB design, the cost can vary from $50 to $2,000. For example, if your PCB design is simple and standard, with few components and a small quantity, you can get PCBs for about $50 each. However, if your design is complex, with many components and a large quantity, the cost can increase to $2,000 or even more. To know the exact cost of your PCB design, you must know the cost of each material used in the PCB. This can vary depending on the supply location, the type of material, the amount of material, and the complexity of the PCB design.

PCB Manufacture Cost

There are many methods of manufacturing PCBs. These include thermal transfer, laser, and inkjet. Thermal transfer is the most common type used in the electronics industry. It’s inexpensive and requires little to no setup time. If you want a fast turnaround time, you’ll need to use a laser-based printer. Laser printers are more expensive when compared to thermal printers, but are much faster. Laser printing is commonly used for high-volume manufacturing.

PCB Assembly Cost

Quantifying the cost of PCB Assembly is a very difficult process because there are so many different factors that come into play. The cost of PCB Assembly can vary widely depending on the vendor, the materials used, the size of the PCB, the location of the PCB manufacturing facility, etc. The more complex your product is, the more expensive it will be to assemble it into a PCB.

PCB Reverse Engineering Cost

The cost of reverse engineering varies greatly depending on the type of project, the complexity of the project, the number of different parts that must be reverse-engineered, and the length of the reverse engineering project.
