What is Reverse Engineering?

Reverse engineering is the process of analyzing a product in order to recreate, duplicate or enhance it. In the context of electronics, reverse engineering involves disassembling a device to understand how it works, identify its components, and create a schematic diagram or design documentation. This process is often used when the original design documentation is unavailable, obsolete, or incomplete.

How do we Prepare Schematics from a PCB?

At Synchronics, we specialize in reverse engineering electronic components to prepare schematics from a printed circuit board (PCB). Here’s how we do it:

Step 1: PCB Inspection

We start by inspecting the PCB to identify the various components, traces, and connections. This helps us understand the layout of the circuit and how different elements are interconnected.

Step 2: Tracing the Circuit

Using specialized tools and equipment, we carefully trace the circuit on the PCB. This involves following the paths of the copper traces to determine how signals flow through the board and where components are connected.

Step 3: Component Identification

Next, we identify each component on the PCB, including resistors, capacitors, integrated circuits, and other electronic parts. We note down the markings, values, and specifications of each component for reference.

Step 4: Creating the Schematic

Based on our findings from tracing the circuit and identifying components, we create a schematic diagram that accurately represents the connections and functionality of the PCB. This schematic serves as a detailed roadmap for troubleshooting, repair, or replication of the circuit.

Step 5: Testing and Validation

Once the schematic is complete, we test it to ensure that it accurately reflects the original circuit design. We validate the connections, analyze the signal paths, and verify the functionality of the circuit to confirm its accuracy.

By following these steps and utilizing our expertise in reverse engineering, we are able to prepare accurate schematics from PCBs, enabling us to repair, modify, or reproduce electronic circuits with precision.
