How the review works
Four simple steps resulting in one definitive readiness status before commitment.
Share product context
What you are building, operating conditions, and design confidence needed.
Provide design evidence
Schematic, PCB, and BOM uploaded securely under our mutual NDA.
Independent assurance
An experienced hardware engineer evaluates risk, evidence, and actions.
Decide with confidence
Receive your Design Assurance Report and track risks through revision.
An Assurance Portal — Not an Insurance Policy.
We exist to dramatically reduce the risk of design failure before fabrication. We do not sell an illusion of guaranteed physical operation.
The Honest Reality of Physical Hardware
Software can be recompiled in seconds. Physical electronic hardware is bound by the real world: silicon batch variations, PCB etching tolerances, SMT reflow thermal profiles, component tolerances under temperature, and firmware timing states.
No engineering review — no matter how exhaustive — can act as an indemnity policy or replace empirical laboratory bring-up. What PreBuild delivers is an independent, rigorous defense against preventable, costly design blunders that ruin first-spin prototypes.
- Radical Risk Reduction: Catching the design errors that most often cause non-booting boards — schematic net mistakes, inverted pinouts, insufficient trace ampacity, and missing bootstrap pull-ups.
- Datasheet Grounding: Verifying decoupling locations, loop inductances, and power sequencing against authoritative manufacturer application notes.
- Objective Third-Party Audit: Unbiased evaluation free from internal designer fatigue or fabricator commercial quotas.
- No Guarantee of Complete Functionality: Even with a verified schematic, software firmware bugs, unmodeled RF EMI in the enclosure, or untested system conditions can affect end-device operation.
- External Physical Variables: We do not control fabricator copper plating variances, assembly cold-solder joints, component batch defects, or handling ESD damage.
- Empirical Validation Required: Prototype review is the essential prerequisite to testing, but board bring-up on a bench with an oscilloscope remains mandatory.
