How Do You Reverse Engineer A PCB?

PCB reverse engineering is a popular technique in this field. Due to this reason, different producers specialize in reverse engineering and sell this service to do successful collaborations with the companies. Reverse engineering for PCBs is highly important, and there are different reasons behind it. It allows you to deeply understand the PCB designs and make the most of them as well.

So that your designs can lead to the practical development of high-quality and industrial-grade PCBs. The reworking of PCBs also becomes easier with reverse engineering. It is also an affordable method t fix the defects of PCBs at the same time. We are going to learn about this technique in detail through this post.

We will try to examine this method from a different perspective. Let’s get started!

What is meant by reverse engineer a PCB?

We need to start our discussion by defining the method of reverse engineering. What is it? How can we define its role? Well, the method of rever engineering means that we are researching the boards and conducting a deep analysis of them for further understanding. You also learn about a PCB’s crucial properties through this method.

It sets a direction for working on a PCB for the technicians. There are other benefits and aspects of this method that we cannot include in the definition alone. The PCB reverse engineering also helps in the development of PCB clones when needed. These will be exactly the same in the performance. It mostly comes in handy when producers are dealing with bulk orders and large-volume production. 

Example of reverse engineer a PCB

Let’s understand this method through a simple example. One of the most typical examples of reverse engineering in the field of PCBs is disassembling the PCBs and then analyzing them for various purposes. You can analyze a PCB when you want to find defects in it, or you want to understand its design and structure deeply. As talked earlier, reverse engineering comes in handy in this regard. A producer can also rely on reverse engineering to make improvements in future PCBs. Also, the technicians and teams can take advantage of reverse engineering and identify their mistakes in case of defective PCBs. There is no doubt that with this method, things become much simpler for you, and you also get a chance to upgrade your PCBs at the same time. 

How To Reverse Engineer A PCB?

Every technique used in the PCB industry has its own set of rules that we should follow. Or else the end result of this process will not be as expected. Also, it will be better to divide this process into different steps to see deeply what’s going on in the process. Experts often recommend sticking to the sequential phases of PCB reverse engineering if we want to drive out positive results from this process. Let’s learn bout these phases below one after the other:

1.    Draw or Scan

You start the process by drawing the PCBs that you want to develop later. If your drawing is not good, you can capture the PCBs and even scan them as alternative options. The purpose is to have a reference at the beginning of the process to make it easier for the overall development. If you are capturing the PCBs, then use a black background so that you can get clear and sharp pictures. You also need to take care of the light and use a good camera because you don’t want to mess up the pictures.

Bad quality and blurry pictures can totally ruin the designs, and reverse engineering results will be poor. Whatever you are going to choose, make sure to seek professional help if you are a beginner. Keep in mind that PCB reverse engineering is an extensive process and you don’t want to start everything from scratch if any of these steps does not take place properly. The next step is the uploading of images. 

2.    Uploading the Image

After you have clicked pictures of PCBs or have drawn the images now, you will upload them on the reverse engineering software that you are using. You can find tons of software for this purpose, depending on your needs. Cropping can be done if needed. Sometimes single software can help you with the entire design, but in some cases, you will have to switch between the software since their features are different. Again, it is a frustrating step, but the results will be worth it in the end. You just have to be well-adhered to your needs and choose the suitable software on that basis. 

3.    Constructing the Layout

It’s time to construct the layout of your PCBs. You need to use 3D visualization and 3D modeling for the development of these layouts. You can easily do this through your reverse engineering software since all of them have this option for creating layouts. Layouts, in this case, are important to showcase the distribution of electromagnetic fields and also provide insights into the performance of circuits to the users.

You can use schematics to have even more in-depth learning about PCB designs. The PCB layouts basically depend on the design and nature of PCBs. Complex PCBs need schematical layouts, which are the most intense. 

We have compiled some crucial tips when it comes to PCB editing. Make sure to keep these tips in mind when you are done with your PCB layouts. Check them out below:

  • Don’t forget to paint the holes and solder pads. By painting, we mean that you need to make upgrades in the pads and improve the efficiency of the holes. Also, make sure that these are tightly connected with the setup.
  • There is no need to linger on the PCB trackpads, and you can use AutoTrace software to exclude them. These are redundant and eventually complicate your PCBs. 
  • Make sure to label the free holes. Free holes neither connect with anything nor join components. These are useless, and you have to label them as well.  
  • Work on the saturation and layers you have added by adjusting them as per your PCB designs. 
  • Untidy PCB tracks will not only confuse you but will also complicate your designs. You need to make sure that these are clean. 
  • Use grayscale on your design by removing the saturation. This process is the desaturation of the PCB images. You will use a white background after this. Combine it with software like AutoTrace to get positive results. 
  • You can simply repeat the same steps on the second side of PCBs because working on the double sides of PCBs is more suitable for the fine engineering of a PCB that meets industrial standards.

4.    Creating Schematics

You can end this process with the development of PCB schematics. A schematic diagram is important to visualize and identify all the individual components of PCBs. This last step in reverse engineering basically prepares you for the practical development of PCBs.

Experts believes CAD is good software for the development of schematics. You can rely on the 2D version of CAD to make it all feasible for you. After this, you will combine it with AutoTrace to make sure everything is in place so that you can make the final changes if needed. When you combine such PCB development software, you ensure precision and design quality. It is important to consider for the producers because, in the end, this thing will lead to flawless and highly integrated PCBs.

When you’re done with the schematics, you will merge the sides of PCBs that you had developed earlier. You also need to name the components so that you can create an exact replica of the PCB design practically. There are different troubleshooting methods available that can save you time in case you need to rework some PCB parts. After making sure your PCB design is ready to interpret, you can begin with the final PCB production.

Drawbacks of reverse engineering a PCB

It is better to take a look at the negative side of PCB reverse engineering. So that you can look for alternatives. In fact, this is important so that you can evaluate your options without any struggle.

  • The tracking of component connections is difficult in most cases.
  • The important equipment used for reverse engineering might be inaccessible.
  • The software used for this process can be highly expensive for some budding producers.
  • The process demands high precision; therefore, the margin of error is next to impossible.

Conclusion

 PCB reverse engineering is important to ensure PCB designs are in place and empower the producers to start production with no worries. Reverse engineering also rules out defects, faults, and technical issues since the process involves different steps in this regard. For the fine interpretation of PCB designs, you can never ignore PCB reverse engineering. 

Different producers will find PCB reverse engineering expensive due to the high-end PCB design tools, but experts consider it crucial for the practical development of industrial-grade PCBs. We have provided all the insightful information regarding this process so that you won’t be struggling with PCB reverse engineering from now on.

Cell phone board

Cell phone board PCB copy

Cell phone PCB copy board, cell phone board with many functions and components, but the PCB space is small, cell phone board PCB copy board rewriting of the wiring design of the restoration to go to the highest. Usually need four to six layers of PCB board. High-power circuits include RF buffers and voltage-controlled oscillators (VCO). Make sure that the PCB board on the high power area at least a block of land, preferably without over-hole above, the more copper skin the better. Sensitive analog signals should be as far away as possible from high-speed digital signals and RF signals.2. Design partitioning can be broken down into physical and electrical partitioning.

Physical partitioning mainly involves component layout, orientation and shielding; electrical partitioning can continue to be broken down into partitions for power distribution, RF alignment, sensitive circuits and signals, and grounding.

Physical Partitioning

Cell phone PCB
Cell phone PCB

Component layout is the key to achieving a good RF design, and the most effective technique is to first fix the components located in the RF path and adjust their orientation to minimize the length of the RF path, keeping the inputs away from the outputs and separating high power circuits from low power circuits as far as possible.

The most efficient stacking method is to arrange the main ground plane (main ground) on the second layer under the surface layer and route the RF lines on the surface layer whenever possible. Minimizing the size of the vias in the RF path not only reduces path inductance, but also reduces false solder points on the main ground and reduces the chance of RF energy leakage to other areas within the laminate.

In physical space, linear circuits like multi-stage amplifiers are usually sufficient to isolate multiple RF zones from each other, but duplexers, mixers, and IF amplifiers/mixers always have multiple RF/IF signals interfering with each other, so this effect must be carefully minimized.

RF and IF alignment

RF and IF alignment should be crossed as far as possible, and as far as possible in between them separated by a piece of ground.

The correct RF path is very important to the performance of the entire PCB board, which is why component layout usually takes up most of the time in the design of cell phone PCBs.

On the cell phone PCB board design, you can usually put the low noise amplifier circuit on one side of the PCB board, and the high power amplifier on the other side, and eventually connect them to the RF side and the baseband processor side of the antenna on the same side through the duplexer. Some skill is needed to ensure that the straight-through holes do not transfer RF energy from one side of the board to the other side, and a common technique is to use blind holes on both sides. The adverse effects of straight-through holes can be minimized by arranging them in areas where both sides of the PCB are free from RF interference. Sometimes it is not possible to ensure sufficient isolation between multiple circuit blocks, in this case it is necessary to consider the use of metal shields to shield RF energy in the RF region, metal shields must be soldered to the ground, must be maintained at an appropriate distance from the components, and therefore need to take up valuable PCB board space. It is very important to ensure the integrity of the shield as much as possible, the digital signal lines into the metal shield should go as far as possible to the inner layer, and it is best to go to the line layer of the PCB is a layer below the ground layer.

RF signal lines can go from the metal shield at the bottom of the small gap and ground gap in the wiring layer, but the gap around as much as possible to lay some ground, different layers on the ground can be connected together through multiple vias.

Decoupling circuit

Many RF chips with integrated linear lines are very sensitive to power supply noise, and usually each chip requires up to four capacitors and an isolation inductor to ensure that all power supply noise is filtered out. An integrated circuit or amplifier often with an open-drain output, so a pull-up inductor is required to provide a high-impedance RF load and a low-impedance DC power supply, the same principle applies to the power supply at the end of this inductor to decouple.

Some chips require multiple power supplies to operate, so you may need two or three sets of capacitors and inductors to decouple them separately. Inductors are rarely placed in parallel, as this creates a null-core transformer and induces interference signals, so they should be at least as far apart as the height of one of the devices, or arranged at right angles to minimize their mutual inductance.

Electrical partitioning

Some parts of the phone use different operating voltages and control them with the help of software to extend the battery operating life. This means that the phone needs to run multiple power supplies, and this poses additional problems for isolation.

Power is usually brought in from a connector and immediately decoupled to filter out any noise from outside the board, then distributed after a set of switches or regulators.

The DC current of most circuits on a cell phone PCB is quite small, so the alignment width is usually not an issue, however, a separate high current line as wide as possible must be run for the power supply of the high power amplifier to minimize the transmission voltage drop.

To avoid too much current loss, multiple vias are required to pass current from one layer to another. In addition, if the power supply pins of the high power amplifier cannot be sufficiently decoupled at its end, then high power noise will radiate throughout the board and cause a variety of problems.

The grounding of high power amplifiers is quite critical and often requires a metal shield to be designed for them. In most cases, it is also critical to ensure that the RF output is kept away from the RF input. This also applies to amplifiers, buffers and filters in the best case scenario, they will be able to operate stably at any temperature and voltage conditions. In reality, they can become unstable and add noise and intermodulation signals to the RF signal. If the RF signal line has to be wound from the input of the filter back to the output, this can seriously damage the bandpass characteristics of the filter.

In order to get good isolation of the input and output, first a ground must be laid around the filter, and secondly a ground should be laid in the lower area of the filter and connected to the main ground surrounding the filter. It is also a good idea to place the signal lines that need to pass through the filter as far away from the filter pins as possible.

In addition, the entire board should be grounded very carefully in various places, otherwise a coupling channel will be introduced. Sometimes you can choose to go single-ended or balanced RF signal lines, the principles of cross-talk and EMC/EMI also apply here. Balanced RF signal lines can reduce noise and cross-talk if routed correctly, but their impedance is usually higher, and to maintain a reasonable line width to get a matching signal source, alignment and load impedance, the actual wiring may have some difficulties.

Can FPGAs be Used to Crack Passwords?

There have been ongoing conversations as to the possibility of using Field Programmable Gate Arrays (FPGAs) to crack passwords. The answer is both yes and no – FPGAs may or may not be used for this purpose.

Find out in this blog post, how possible it would be to crack passwords or not using Field Programmable Gate Arrays (FPGAs).

The FPGA Hashcat Perspective

This was the earliest proposal for cracking passwords with the aid of FPGAs. It has to do with the combination of Field Programmable Gate Array (FPGA) and Hashcat.

The idea is to leverage the fusion of the two and the remodification capabilities of the FPGA’s ICs to facilitate password hacking.

Today, FPGA Hashcat has given way to newer methods. Some of the reasons for the limited usage are the high-end hardware required for the process, lengthened compilation time (assuming the FPGAs were compatible with OpenCL) and need to repeat the processes after each successful hack.

What Next?

FPGA Crack
FPGA Crack

The reduced dependence on FPGA Hashcat can be attributed to the newer technologies used for FPGA crack. The most popular is the use of FPGA Clusters.

What are FPGA Clusters?

They are the combination of different Field Programmable Gate Arrays (FPGAs), with the purpose of accelerating code/password cracking and cryptographic algorithms.

How to Crack Codes and Passwords with FPGA Clusters

Based on previous studies, it has been ascertained that a cluster of commodity Field Programmable Gate Arrays (FPGAs), when placed in a single 4U chassis, can be able to deliver up to 2,000 dual-core processors worth of computational power.

This is, of course, subject to the fact that the single 4U chassis consumes less power, typically under 1,400 watts.

Why FPGA Clusters are Popularly Used for Code Cracking

There are a couple of reasons that suggest why the use of clusters of FPGAs can make a lot of differences in cracking codes.

Here are some of the reasons:

Chassis-Fitting

Due to the requirement for the clusters to be used with the 4U chassis; it makes sense to use something that fits.

FPGAs comfortably fit into the chassis. This, in turn, gives room for the forensic users to easily construct the racks stuffed with the FPGA-based systems.

Better Optimization

You want to work with a tool that assures of the best FPGA crack solutions. That is what you get from using the FPGA clusters.

Here is why it matters:

  • The clusters of FPGAs tend to offer a significant performance more than the Graphics Processing Units (GPUs) do.
  • You can also use the clusters for specific tasks, such as recovering passwords.

Excellent Power Management

It is one thing to use FPGA crack methods to obtain passwords and crack codes. It is an entirely different thing to use the same method effectively.

You can be sure to maximize power with the clusters of FPGAs, as they consume less power and don’t generate much heat.

Important Considerations for FPGA Clusters

Using clusters of Field Programmable Gate Arrays (FPGAs) is not without some stresses. Here are some of the things to consider before making the decision to use them:

  • Field Programmable Gate Array (FPGA) clusters tend to cost more per teraflop of performance they bring forth.
  • The clusters do not support all the software algorithms.

GPU Clusters – Another Option Worth Exploring

IC Crack Service
IC Crack Service

Besides the clusters of FPGAs, it is also possible to use the clusters of Graphics Processing Units (GPUs).

Here are a couple of quick takes before we delve into the discussion:

  • These clusters are based on GPU-accelerated workstations.
  • They are also based on consumer-grade video cards.
  • GPU clusters are used for a variety of purposes, such as cracking the passwords used to protect Wi-Fi communication systems. The clusters also aid the cracking of passwords stored in Apple devices and those used to protect office-related databases.

How the GPU Clusters Work

These clusters are regarded as a faster route to obtaining passwords and cracking codes. They can also be cost-saving in some way.

Here is the rest of the things you need to know about using GPUS clusters instead of FPGAs for code cracking purposes:

Significant Performance Boost

One of the important considerations for cracking code and hacking/obtaining passwords is speed. If the process is sped up, you will be through in the shortest time possible.

If that is the case, you can rely on the clusters of GPUs, due to the speed of the graphic cards – especially those based on the Graphics Core Next architecture by AMD.

The other aspects of GPU clusters’ acceleration capabilities include:

  • The support for thousands of stream processors.
  • A cluster of 4 graphics cards (either from NVIDIA or AMD) potentially provides up to 1000 dual-core Central Processing Units (CPUs) in a single chassis.

Downsides to GPU Clusters

Despite relegating traditional CPU usage to the background, GPU clusters are still not completely free of some challenges.

The major downsides include non-optimization for the task of recovering passwords.

FPGA Clusters vs. GPU Clusters

Both the clusters of Field Programmable Gate Arrays (FPGAs) and Graphics Processing Units (GPUs) have distinct benefits. On a closer look, one can see that the FPGA clusters have the upper hand.

Here is how they compare:

Heat Generation

When a cluster of 4 graphics (video gaming) cards is installed in a single computer, there is a chance of increased heat generation. Depending on the card, the power it sucks could be up to 300 watts.

This is higher, when compared to the less heat generated when using the FPGA clusters. These clusters provide up to 2,000 dual-core processors of computational power, without sacrificing excess heat generation.

Cost Considerations

The GPU clusters are you go-to for savings costs when cracking codes and recovering passwords. They cost less per teraflop of performance than the FPGA clusters do.

Conclusion

Field Programmable Gate Arrays (FPGAs) are becoming faster than the GPU clusters are. With the reduced heat generation, the improved performance and the optimizations, there is no doubt that you can use these to crack codes faster.
