When source files are missing or obsolete, we document the existing hardware, rebuild schematics and layout data, identify components and prepare a reviewable path to repair, reproduce or redesign the product.
Core capabilities
Capture dimensions, layers, markings, connectors and key construction details.
Trace circuits and rebuild readable functional schematics.
Identify components, values, packages and sourcing alternatives.
Rebuild layout, footprints and manufacturing outputs as scope allows.
Replace obsolete parts and address known reliability or compliance issues.
Document assumptions, open items and comparison checks before release.
Design workflow
Typical applications
Share your requirements, existing files and production targets. Our engineering team will recommend a practical next step.

Practical answers about files, schedule, engineering support, production coordination and confidentiality.
For PCB Reverse Engineering, provide clear photos, available boards or samples, dimensions, connector and component details, known functionality, required deliverables, and any existing drawings, BOMs, firmware information or test requirements you are authorized to share.
Lead time depends on design maturity, complexity, quantity, material or component availability, testing scope, and how quickly engineering questions are resolved. We confirm the schedule after reviewing your files; urgent prototype or quick-turn options can be discussed where the required process and materials permit.
We can review common production outputs such as Gerber and ODB++, as well as native EDA data when agreed during the file review. Because library versions, third-party models and tool releases vary, tell us the software and version used before transfer so we can confirm the working format or recommend a neutral export.
Yes. Existing hardware is the normal starting point, provided you own the design or are authorized to reproduce it. We first agree the reconstruction depth, verification method and deliverables because copying connectivity, rebuilding editable CAD and redesigning obsolete sections are different scopes.
Yes, SI/PI analysis can be coordinated when manufacturing or assembly risk depends on controlled impedance, return paths or power integrity. It is a separate engineering scope and requires suitable design data, stackup information, models and acceptance criteria.
Yes. Excel Circuit can coordinate engineering review, PCB fabrication, component sourcing, assembly, inspection and testing under one project. You may also order only the engineering stage and release the approved production package to another manufacturer.
Project files are limited to personnel and qualified partners who need them for quotation and delivery. Excel Circuit uses reasonable technical and organizational safeguards, does not publish customer designs without permission, and can work under a mutually agreed NDA. Your signed NDA or project agreement controls where it provides specific protections.
Final scope, price and lead time are confirmed after engineering review of your current files and requirements.
