When no off-the-shelf product solves the problem — requirements, schematic, board, enclosure, firmware and a prototype you can put in front of the people who have to use it.
Custom electronics are worth building when the alternative is bending a commercial product into a shape it was never meant to hold. The risk is that a one-off becomes an orphan nobody can service. We manage that by designing for manufacturability and serviceability from the start, documenting the design so it can be built by someone else, and being candid when a standard product would genuinely be the better answer.
Functional requirements, environment, power, interfaces and regulatory path defined before design starts, because those constraints determine most of the architecture.
Schematic capture, layout with attention to signal integrity, power distribution and thermal, and a stackup appropriate to the speeds involved.
Working hardware early. Bring-up, test fixtures, and revisions driven by measurement rather than assumption.
Industrial control assemblies built to a listed panel standard, with the field wiring, enclosure rating and disconnect coordination handled as part of the design.
A written specification with acceptance criteria. Ambiguity here is the most expensive defect in the whole process, because it is not discovered until hardware exists.
Parts chosen for availability and lifecycle as much as specification. A perfect component on a two-year lead time is not a component.
Schematic, layout, mechanical fit and thermal check, followed by a design review against the specification before anything is fabricated.
Assembly, bring-up, functional test against the acceptance criteria, and environmental checks where the application demands it.
Pre-compliance testing for emissions where the product requires it, then a documentation package: schematics, bill of materials, fabrication and assembly files, test procedure and source.
Code editions are revised periodically and local authorities amend them. The requirements that apply to your project are confirmed against your jurisdiction during design.
Often it is not, and we will say so. Custom is justified when the requirement is genuinely unserved, the volume supports it, or integration constraints make a commercial product unworkable.
You do. The deliverable includes the files needed to have it built by someone else. A design you cannot take elsewhere is a liability.
The path depends on the product and market. We identify it during definition and do pre-compliance work in-process, because finding an emissions problem at the accredited lab is the expensive version.
Tell us the building, the constraints and the deadline. We will tell you what the work actually involves before anyone quotes a number.
