Engineering
These pages hold the engineering practice that Scadys applies across every product, rather than to one board. The product pages describe what each board is. These pages describe how a Scadys board is designed so that it can be built and tested by hand, and how a new prototype is brought up, checked for emissions and repaired.
Sections
| Section | Covers |
|---|---|
| Circuit design principles | Design for prototyping: test points, isolating circuit blocks with DNP parts, part sizes for hand assembly, double-sided boards, bed-of-nails interfaces, programming connectors and thermal relief. |
| Parts | Rules for particular part families, starting with MLCC land patterns and flex cracking. |
| Bring-up and verification | The general method for bringing up a new prototype: core steps for every board, function modules chosen per board, the in-house EMC pre-scan and fault-finding. |
What earns a page here
A rule or a method earns a page here when three things are true:
- it applies to more than one product;
- getting it wrong costs far more than getting it right; and
- the reason is not obvious from the schematic or the board, so it would be lost if it were not written down.
Why these are published
Scadys documentation is written first for the engineer who has to maintain the boards, and second for anyone evaluating them or building one. A rule that lives only in a footprint file, or in one person's memory, is undone by the next person who does not know it is there.
