A working prototype is roughly a third of the way to a shippable consumer electronic product. The rest is a disciplined sequence of pilot builds, certification and process control that turns one hand-assembled unit into ten thousand identical ones. This guide walks the stages, the money and the four failure modes that push launch dates.
The three pilot builds
- EVT — engineering validation. 20-100 units, often on soft tooling. The question is only: does the design work? Expect schematic revisions and mechanical fit changes.
- DVT — design validation. 100-500 units on production-intent tooling and processes. Full environmental, drop, life and compliance pre-testing happens here. After DVT the design should be frozen.
- PVT — production validation. 500-2,000 units built by factory operators at line rate, with no engineers rescuing units. You are validating the process and measuring yield, not the design.
- MP — mass production. Ramp only after PVT yield holds above your target, typically 95 percent or better at final test.
Where the money goes
Cost item | Typical range | Notes |
|---|---|---|
Injection mould tooling | $8k-$60k per tool | Family tools reduce count; steel grade sets tool life |
EVT / DVT / PVT builds | $15k-$120k total | Includes scrap, rework and travel |
FCC, CE and UKCA testing | $8k-$35k | Retests after any RF-affecting change |
Safety and battery (UL, UN38.3) | $5k-$25k | Required for lithium cells and shipping |
Test fixtures and jigs | $5k-$40k | One per station; often underbudgeted |
Packaging design and drop testing | $4k-$20k | ISTA testing before the first container |
Per-unit cost stacks up from PCBA, enclosure with amortized tooling, assembly labour, test time, packaging, freight and duty. A useful rule: if your landed cost is not roughly a quarter of intended retail, the model will not survive retail margins and returns.
Certification is a schedule item, not a formality
Any product with a radio needs FCC in the United States and CE or UKCA in Europe, and labs book out weeks ahead. Lithium batteries add UN38.3 transport testing before any air freight. The trap is sequencing: teams change an antenna, a plastic wall thickness or a supplier after testing and unknowingly invalidate the report. Freeze the RF-relevant design at DVT and book the lab slot then. Pair this with design for manufacturing work so the frozen design is also the cheap one.
Four things that actually slip schedules
- Component lead times. One 40-week microcontroller can hold a whole build. Design in second sources during schematic, not during a shortage.
- Tooling changes. Every steel change costs one to three weeks. This is why DVT exists.
- Certification retests. Budget one retest by default.
- Yield below target. Sub-90 percent yield at final test quietly doubles labour cost and delays ramp until the root cause is found.
Frequently asked questions
What are EVT, DVT and PVT in consumer electronics manufacturing?
They are three escalating pilot builds. EVT proves the engineering works, DVT proves the production-intent design passes all testing, and PVT proves the factory process can build it repeatably at line rate. Mass production starts only after PVT yield is acceptable.
How long does it take to manufacture a consumer electronic product?
From frozen design to first shipped container is typically six to twelve months: four to eight weeks for EVT, six to ten for DVT, four to six for PVT, plus certification and tooling lead times that often run in parallel.
What is a realistic minimum order quantity?
Most contract manufacturers want 3,000-10,000 units a year to justify setup. Smaller runs are possible with domestic or low-volume assemblers, but unit cost rises sharply because tooling and setup amortize over fewer units.
Should I manufacture in Asia or domestically?
Asia still wins on unit cost at volume for mature electronics. Domestic assembly wins on communication speed, IP control, tariff exposure and small runs. Many programs split it: PCBA offshore, final assembly and test onshore.
We prepare designs for manufacture, run pilot builds and manage certification so the ramp does not stall.
