Our Reverse Engineering Services

We support customers requiring PCB reconstruction, replacement and re-design services when original design files are unavailable or incomplete.

PCB Reverse Engineering

Our engineering team can analyze existing printed circuit boards and recreate critical manufacturing data, including Gerber files, schematics and bill of materials (BOM) information when available.

PCB Cloning

When original design files are unavailable, we can recreate PCB manufacturing data from existing boards to support replacement, maintenance and continued production requirements.

PCB Re-Design Services

We can modify and improve existing PCB designs to address component obsolescence, manufacturing challenges, cost reduction goals and performance improvements.

Obsolete PCB Replacement

We help customers replace legacy and discontinued circuit boards used in industrial equipment, control systems, medical devices and other long-life electronic products.

What Information Can We Work From?

Depending on the project, our engineering team can work from a variety of sources to help reconstruct PCB manufacturing data and support reverse engineering requirements.

Existing PCB

A fully assembled or bare PCB can often provide enough information to begin the reverse engineering process.

Damaged Circuit Board

Even damaged or partially functioning boards may contain valuable information for reconstruction and analysis.

Gerber Files

Existing manufacturing files can help accelerate PCB reconstruction, verification and redesign activities.

Schematics

Available schematics can assist with circuit analysis, component verification and design recovery.

Bill of Materials (BOM)

Component lists help identify parts, alternatives and obsolescence risks during reconstruction projects.

Technical Documentation

User manuals, drawings, specifications and other documentation can provide valuable design information.

Typical Reverse Engineering Projects

We support a wide range of reverse engineering and PCB reconstruction projects across industrial, commercial and legacy electronic applications.

Industrial Control Systems

Replacement and reconstruction of PCBs used in industrial machinery, automation systems and factory equipment.

Legacy Electronic Equipment

Recovery of manufacturing data for discontinued products where original design files are no longer available.

Medical Devices

Support for replacement boards and redesign projects used in medical and diagnostic equipment.

Test & Measurement Equipment

PCB reconstruction services for laboratory instruments, testing systems and measurement devices.

Telecom Equipment

Reverse engineering and replacement of communication and networking hardware circuit boards.

Commercial Electronics

Support for repair, redesign and replacement of electronic products requiring updated manufacturing documentation.
