We develop a functional replacement for a discontinued, unavailable or uneconomical board while preserving the interfaces and system behavior that the equipment actually needs.
You do not need to prepare formal engineering terminology before contacting us. A clear business or equipment problem is enough for an initial technical discussion.
The exact deliverable set is agreed before the stage starts so acceptance is based on concrete engineering results rather than activity.
We select the architecture and tools according to interfaces, timing, environment, maintainability and production constraints.
The target is normally functional compatibility, not a literal copy of every legacy design decision. We identify the properties that the host equipment depends on and reproduce those deliberately.
If documentation is missing, reverse engineering is performed first. The replacement is then designed on a current component base with the agreed mechanical and electrical constraints.
The acceptance criteria are defined before detailed design so compatibility can be verified objectively.
Original-board characterization
Interface and behavior specification
New schematic and PCB
Firmware where required
Compatibility testing
Production documentation
Questions that are useful to settle before the initial estimate.
A working sample is strongly preferred because it provides a behavioral reference. A non-working sample can still be useful for destructive analysis.
Often yes. If external behavior and protocols are known or can be measured, the software can be implemented independently.
Usually not. The goal is a documented, manufacturable and compatible product, not duplication of unnecessary legacy internals.
Yes, when drop-in mechanical compatibility is part of the requirements.
We agree the electrical and functional criteria, then compare the prototype on a bench and, where possible, inside the target equipment.
Send photos, dimensions, connector information, equipment context and any sample or manual available for the original module.
