Many clients do not have the original PCB schematics or source code. Through high-precision reverse engineering, we can extract the schematic, BOM, and PCB layout directly from the physical board—allowing complete design restoration without any original documentation.
Many customers come to us with only a physical board—no schematics, no PCB layout files, and no source code. That’s not a problem. With our advanced reverse engineering capabilities, we can fully recreate the original board design based on the sample you provide.
Using a combination of high-resolution scanning, manual measurement, and professional analysis tools, our engineers extract trace paths, netlists, and component placements from the physical board. We then rebuild the schematic diagrams, generate the full PCB layout, and produce a complete BOM (Bill of Materials) with accurate specifications and part numbers.
For boards with embedded firmware, we also evaluate whether code extraction or functional logic recreation is feasible. Our goal is to deliver a working digital version of your hardware—even if the original documentation has been lost or was never available.
This service is ideal for product restoration, legacy system replacement, international sourcing transitions, and rebuilding discontinued modules. You only need to provide us with a working (or even damaged) PCBA—we’ll take care of the rest, from reverse design to new sample production.
We don’t just replicate the physical layout—we precisely restore the full electrical functionality of your original PCBA. Our engineers analyze every layer, routing pattern, and signal path to ensure the cloned board performs identically in real-world conditions.
Whether your board is a multilayer structure, involves mixed-signal circuits, or includes power-sensitive or timing-critical areas, we match impedance, signal delay, and grounding structures to guarantee stable operation. Even the smallest routing details and component footprints are carefully mirrored.
All cloned boards are tested side-by-side with the original using oscilloscopes, multimeters, and functional testers to verify matching signals, outputs, and timing behavior. This ensures seamless replacement without software, firmware, or system-level adjustments.
Our 1:1 cloning solution is ideal for legacy equipment support, replacement of discontinued products, or maintaining critical systems where documentation is missing—but precision is non-negotiable.
We extract and rebuild the full BOM from the original board, replacing obsolete parts with cost-effective, compatible alternatives for stable production.
We extract full component lists from physical PCBs, including part numbers, values, packages, and key specs—ensuring a clear starting point for re-manufacturing.
When original parts are obsolete or hard to source, we recommend compatible replacements with equal performance, footprint, and reliability standards.
We help reduce cost and procurement risk by selecting parts with stable supply, competitive pricing, and shorter lead times from trusted vendors.
Every BOM we deliver is version-controlled and traceable, with supplier info and datasheets included—simplifying audits, sourcing, and production.
We offer firmware extraction where feasible, or assist clients in reconstructing program logic and redeveloping embedded code based on the board’s functional behavior.
For PCBA boards containing embedded firmware or microcontroller code, we provide expert-level support for firmware extraction and logic reconstruction. If the original source code is unavailable, our engineering team will evaluate the board’s architecture and attempt to extract the firmware from the onboard memory using safe, non-destructive methods.
In cases where extraction is not feasible or the code is encrypted, we offer functional analysis and logic rebuilding services. By observing system behavior and signal responses, we help customers recreate program logic and restore original functions—even without access to the original development environment.
Our team works closely with clients throughout the process, discussing functional expectations, user interface behavior, I/O timing, and application requirements. Whether your board uses standard MCUs, custom controllers, or legacy chipsets, we help bring firmware-dependent systems back to life.
This service is ideal for legacy system recovery, discontinued product support, or low-volume electronics maintenance—where keeping the original functionality is critical but source files no longer exist.
Our state-of-the-art manufacturing facility is equipped with a range of advanced machinery and technologies designed to deliver high-quality and precise PCBAs. We utilize automated pick-and-place machines that offer unparalleled precision in component placement, ensuring perfect alignment even for the smallest components. These machines are integrated with advanced vision systems that enable real-time inspection during assembly, minimizing defects. To achieve superior soldering quality, we use high-efficiency reflow soldering ovens and selective soldering systems, which are capable of handling complex boards and ensuring consistent, reliable solder joints across all components.
For quality control, our facility is equipped with Automated Optical Inspection (AOI) systems that meticulously examine every board for potential defects, guaranteeing that only flawless products pass through to the next stage. We also use X-ray inspection technology to inspect multi-layered boards, ensuring there are no hidden defects that could affect signal integrity or performance. Our electrical testing equipment checks every circuit to ensure all electrical properties meet the required standards, particularly for high-frequency applications.
Yes. As long as you can provide a physical sample (working or damaged), we can reverse-engineer the schematic, PCB layout, and BOM—even without original documentation.
Absolutely. We conduct side-by-side electrical, signal, and functional testing to ensure the cloned board performs identically in real-world applications.
Yes. Our engineers will identify equivalent or compatible alternatives for outdated parts, ensuring the same functionality and compatibility in the final product.
We can attempt firmware extraction where technically feasible. If not possible, we offer functional logic reconstruction and firmware redevelopment based on board behavior.
Initial prototype delivery usually takes 5–7 working days after analysis. For urgent projects, we offer expedited service depending on board complexity.
We are capable of cloning advanced PCBs with 12 or more layers, supporting complex structures such as HDI, blind/buried vias, and controlled impedance. This service is ideal for high-end applications in industrial automation, medical equipment, and other demanding sectors.
Every cloned board undergoes electrical testing, functional verification, and AOI inspection before delivery—ensuring performance identical to the original board, with stable and reliable results.
Every cloned board undergoes a full range of quality tests before shipment to guarantee performance that matches the original. We carry out electrical performance checks, functional testing, and full AOI inspection to detect any deviations in signals, solder quality, or board behavior.
Functional tests are conducted side-by-side with the original board, using test jigs, multimeters, and oscilloscopes to compare signal outputs, timing, and response accuracy. For high-reliability applications, we also offer thermal and aging tests to ensure long-term stability.
Our AOI systems perform micro-level visual inspections on every solder joint and component placement, ensuring consistent build quality across all units.
This rigorous testing process ensures that every cloned board is not only physically identical—but also functionally equivalent, stable, and ready for end-use without risk.
To ensure consistent quality and reliability in high-volume PCBA production, we employ a comprehensive quality control system at every stage of the process. From sourcing premium materials to final assembly, every step is closely monitored. Advanced technologies such as Automated Optical Inspection (AOI), X-ray inspection, and functional testing allow us to identify defects early, preventing quality discrepancies between batches. Our automated production lines ensure precise and uniform assembly, while strict process controls and real-time monitoring maintain consistent output. We also implement traceability systems, ensuring transparency and accountability across all production batches. Continuous staff training ensures that our team is always aligned with the latest quality standards and best practices, guaranteeing that every PCBA meets the highest performance and reliability requirements, even in large-scale production.
