PCB Clone / PCB Reverse Engineering

What is PCB Reverse Engineering

PCB reverse engineering (also known as PCB clone, PCB copy, PCB duplication, or PCB RE) is the process of analyzing an existing physical Printed Circuit Board (tarjeta de circuito impreso) and recreating its design to produce a functionally identical copy.

This process includes several technical steps:

  • Extracting schematic diagrams

  • Generating Gerber files and PCB layout

  • Creating a Bill of Materials (Proseperar)

  • Using IC unlock technology to extract Bin or Hex code from programmable ICs

  • Reproducing the board through:

    • PCB fabrication

    • Component soldering

    • Flying probe testing

    • Circuit debugging

✅ The goal is to fully duplicate the original circuit board and ensure the same functionality.

What We Need from You

To initiate PCB or PCBA cloning, please prepare:

  • At least 2 physical samples of the PCB or PCBA

How to Clone a PCB / PCBA

1️⃣ Draw, Scan, or Photograph the PCB

  • Take clear photos of both sides of the board

  • Use a dark background to improve contrast (especially for boards with through-holes)

  • Use a high-resolution camera with sufficient lighting

  • Optionally, draw the layout on graph paper for simpler boards

2️⃣ Upload the Image

  • Crop the image to focus only on the PCB

  • Upload it to your reverse engineering software

  • Use photo editing tools to enhance visibility and highlight key features

3️⃣ Construct the PCB Layout

  • Use software (P.EJ., AutoTrace) to convert images to vector graphics

  • Build a 3D PCB layout to analyze electromagnetic behavior and circuit patterns

Editing Steps per Side:

  • Paint holes and solder pads

  •  Remove PCB trackpads to avoid conversion loops

  • Mark unconnected holes

  • Adjust saturation and layers

  • Clean tracks and smooth edges

  • Convert to grayscale and invert for clear tracing

  • Repeat for both sides of the PCB

4️⃣ Create the Schematic Diagram

Once the layout is complete:

  • Generate 2D schematic drawings using CAD or layout software

  • Label each component and connection with standard symbols

  • Combine both sides of the board into a full schematic

Use this schematic to:

  • Troubleshoot

  • Modify

  • Repair

  • Reproduce the PCB
