The Ultimate Introduction to PCB Clone

PCB clones have been widely used in modern industry. It not only can be used for electronic product manufacturing but also for scientific research, aerospace, medical equipment, and other fields. Meanwhile, with the continuous development of technology, the precision and efficiency of PCB copy technology are also improving. This blog will delve into the world of PCB cloning, which is a technique used in electronic manufacturing.

What is PCB Clone?

Cloning a printed circuit board is to replicate an existing printed circuit board process. In this process, the design and functionality of the original printed circuit board are copied through a reverse engineering procedure. Once the design and functionality of the board have been completely duplicated, a new board can be produced that is the same as the original board. In the absence of the original design files, cloned circuit boards can be used for redesign.
PCB duplication contains a huge amount of energy. This energy is not only for the PCB design service enterprises but also for the whole electronic product market and the information technology industry because objectively they promote the technical ability of Chinese enterprises and completely break the technical barriers.
The PCB copy board involves obtaining circuit board samples, data extraction, and processing, designing circuit boards, fabricating circuit boards, soldering components, testing and debugging, etc. So, it requires excellent skills and careful patience to ensure the stable and efficient operation of the PCB circuits after copying.

Advantages of PCB Cloning

Generally speaking, the value of PCB copy board is reflected in the following aspects:
  • Shorten the time to market: PCB cloning can help companies quickly update and keep up with the latest trends. With the shortest time and the lowest development costs to complete the product listing. Product quality is strongly guaranteed due to the support of the current almost perfect electronic cloning technology.
  • Improve the cost-effectiveness of the product: Good quality and low price is its most prominent feature, easy to accept by the public, not only can enrich people’s lives, experience the new feeling brought by fashion and trends, and win more profits for the enterprise, enhance its competitiveness in the industry.
  • The key to success: PCB copy is not from time to time simple imitation and copy, it belongs to the field of reverse research. PCB copy board can be secondary development, that is, in a full understanding of the schematic diagram based on the function of its deletion, to achieve their own needs for the product. It avoids “intellectual property rights” and allows for the rapid creation of new brands with short lead times, low costs, and significant benefits.
  • Accelerate the development of the overall electronics industry: when the cloning technology is developing faster and faster and becoming more and more perfect, electronic engineers are also actively seeking how to other newly developed products in the market for a long time to maintain the competitiveness of a unique, enhanced product differentiation methods, which on the one hand promotes the study of forward technology, on the other hand, also makes the reverse research to get a broader space for development, but also to the electronic enterprise. It also brings more opportunities for electronic enterprises.

Process of PCB Cloning

The PCB Cloning process involves several steps, and understanding each step is important to recreate the replica of the original PCB. Let’s delve into the details of each step.

Step 1: Preparation

The 1(st) step involves gathering the equipment such as original PCB, CAD software, scanners, and testing equipment. This equipment helps in the various stages of PCB cloning such as the CAD software helps to recreate the schematic and layout designs, and scanning instruments help us to capture the detailed images of the PCB. To understand the electrical properties of PCB board, different testing instruments such as ammeter, voltmeter, and oscilloscopes are used. The 1(st) step led the foundation for the cloning process as it gives insights into the design layout and specific components used.

Step 2: PCB Scanning

The 2(nd) step in the PCB cloning process involves the scanning of PCB using different advance scanners such as optical scanners and X-ray scanners. High resolution images are captured using the optical scanners. X-rya scanners on the other hand are used to inspect the PCB board layers and connections. With the help of these scanners a detail digital representation of component placements, pads and vias are extracted. The accuracy in the scanning process ensures minimum errors and help to accurately replicate the original design.

Step 3: Schematic Recreation

In the 3(rd) step, professional software such as Altium Designer is used to recreate the schematic of the original design. The schematic recreation required in-depth analysis of the design to ensure that all the components and their connections are accurately mapped. This step in the cloning process is most important as it ensures that the PCB works identically to the original.

Step 4: PCB Layout Design

The schematic design acquired in step 3 serves as the foundation for the PCB layout design. The PCB layout is redesigned using the CAD software. To exactly clone, it is important to ensure that all the components are in their exact locations. This step in the cloning process is vital, as it ensures the cloned PCB will work identically to the original.

Step 5: Prototype Manufacturing

Once the schematic and layout design are finalized, the next step is to fabricate the PCB clone prototype. The fabrication process involves the standard fabrication techniques and embedding the components onto the PCB.

Step 6: Validation & Testing

In the PCB cloning process, the final step is the PCB design validation & testing. This is achieved by comparing the original PCB with the cloned PCB by performing functional tests and troubleshooting to ensure that the clone PCB is a replica of the original board. The goal in the final step of PCB Cloning is to ensure that the cloned PCB is indistinguishable from the original PCB in terms of performance and functionality.

Applications of PCB Cloning

At present, the scope of PCB copy board is expanded to medical equipment, communication terminals, consumer electronics, industrial control, instrumentation, broadcasting and television, automotive electronics, home electronics, security electronics, processing and manufacturing equipment, and other electronic product applications.
PCB cloning has a range of applications in different fields.
  • Reverse Engineering: Reverse engineering techniques help companies to clone the competitor PCBs and get insights into their designs. Using reverse engineering, companies learn from the existing PCB designs and replicate the designs.
  • Obsolete Components Replacement: Engineers replace the obsolete components with updated components using the cloning process.
  • Research & Development: PCB cloning helps companies accelerate the research & development process with quick iterations and modifications of the existing designs.
  • Cost Reduction: With PCB cloning the expensive designs can be replicated which results in the reduction of cost.

Challenges in PCB Cloning Process

  • Legal Issues: While PCB cloning offers numerous advantages, it also raises legal considerations such as intellectual property rights. So, before the cloning process, it is important to ensure that it does not infringe on patents.
  • Technical Difficulties: Cloning a complex PCB, especially with multilayer, can be challenging. Thus, accurate scanning and schematic recreation are essential to overcome these challenges.
  • Quality Control & Reliability: In depth testing and validation is essential to ensure that the PCB comply with all the quality and reliability standards.


PCB cloning is a useful technique with numerous applications including electronic manufacturing, reverse engineering, and research & development. While PCB cloning is a helpful tool in the electronic manufacturing industry, it also poses significant ethical considerations such as patents and intellectual property rights. So, ensuring responsible use of cloned designs is essential, as unauthorized cloning can lead to legal repercussions and damage a company’s reputation.
