Device Recovery and Reverse Engineering
Recovering and re-manufacturing undocumented devices — schematic reconstruction, replacing obsolete components with modern equivalents, a new board revision.
Typical project:Recovery of an undocumented industrial board· 2–5 weeks
Project
Tell us briefly about the project: what you want to build, which functions it needs, the rough timeframe. If we have done something similar we will send an example.
Analysis and schematic recovery of undocumented boards, replacing discontinued components with modern equivalents, restoring lost firmware.
The question in this area is not repair: "the device is out of production, there are no spares, and we still need it — build us a new one". The goal is not to get one board running but to make that function manufacturable again.
The work starts with reconstructing the schematic: the board is traced under a microscope, components are identified, the circuit is rebuilt. Obsolete parts are then replaced with modern equivalents — which often means delivering the same function with fewer components.
The result is a new PCB revision with full documentation. The device is no longer hostage to an unobtainable part: next time it is needed, you simply order another batch.

Technologies we work with
From concept to production
- 01
Consultation and Requirements Analysis
We jointly define the project's goals, functional requirements, and budget/timeline constraints. NDA signed if needed.
- 02
Architecture and Schematic Design
System architecture, part selection, schematic drafted. Initial BOM and PCB block diagram agreed upon.
- 03
PCB Layout and Firmware
PCB design (KiCad/Altium), signal integrity, EMC checks. Firmware developed in parallel. Interim reviews.
- 04
Prototype and Testing
First PCB batch assembled and lab-tested. Validation with firmware. Required adjustments.
- 05
Production and Support
DFM optimization for mass production. Documentation, user manual, long-term technical support.
