Manufacturing Plan

01

Why This Doc Exists

The architecture doc's cost reference says what the parts should cost. It doesn't say how those parts turn into manufactured units — who builds them, what it costs to get a production line stood up before the first unit ships, how the per-unit price actually moves with order volume, or how long that takes. This doc covers that gap: contract manufacturer (CM) landscape, tooling/NRE, the volume price curve, and a phased NPI (new product introduction) timeline.

Kestrel Silicon KX2 doesn't exist yet — same problem the SteamOS POC doc works around for launcher/UX validation. That fact splits everything below into two different plans. §02 covers the split before any CM/tooling number here means anything.
02

The Silicon Gap Sets the Real Timeline

Two paths to a manufacturable SoC, and they don't share a timeline, a budget, or a risk profile. Every schedule and cost figure later in this doc assumes Path A — Path B is the honest long-lead alternative, not a near-term option.

PathWhat it isLead time to samplesNRE
A — Off-the-shelf ARM SoCSubstitute an existing mobile-class part (Cortex-A73/A55-class, same tier the SteamOS POC uses reference hardware for) for KX2 at launch4–6 months~$0 (uses vendor's existing die)
B — Custom KX2 tape-outFabless design through a foundry (mask set, IP licensing, verification, packaging) for the bespoke part the architecture doc costs at $18.0018–24+ months$15M–$40M+
Path A isn't free of consequence: a catalog SoC almost certainly prices above KX2's assumed $18.00, which moves the ~$96.80 total BOM up and narrows the margin story in the architecture doc's retail price estimate. Path B preserves that number but needs volume and funding commitments this doc has no basis to assume yet. Everything from §03 onward plans against Path A; Path B stays a later-stage decision, not a blocker to starting CM conversations now.

Contract Manufacturer Landscape

Handheld-class consumer electronics manufacturing sorts into a few recognizable tiers. These are industry classes with illustrative reference points, not vendors under contract for Kestrel — the point is knowing which tier a real RFQ round should target.

CM classReference pointTypical MOQFit for Kestrel
Tier-1 EMS (large-scale)Foxconn/BYD Electronics-class contract assemblers100K+ unitsOverbuilt for a first run; the line-setup cost only pays off at scale Kestrel doesn't have yet
Boutique handheld ODMShenzhen-based ODM class behind Anbernic/Miyoo/Retroid-style retro handhelds1K–5K unitsBest fit — already tools for PSP-scale enclosures, dual analog sticks, and small-battery handhelds at low MOQ
White-label PCBA + local assemblyContract PCB assembly house + separate final-assembly shop500–2K unitsLowest MOQ, but Kestrel owns integration risk the ODM would otherwise absorb
This tracks the same tier the original PSP-1000 and Steam Deck LCD BOM comparisons in the market comparison doc imply — Kestrel's BOM and volume are much closer to a boutique handheld ODM's normal order size than to a Tier-1 EMS's.

Tooling & NRE Cost Reference

Engineering estimate for a Path A first run at a boutique handheld ODM, before any per-unit BOM spend. Excludes Path B silicon NRE (§02).

ItemCategoryEst. Cost
Injection mold tooling (shell + mid-frame, 2-cavity)Mechanical$60,000–$110,000
PCBA test jig / ICT + FCT fixturesTest$15,000–$30,000
Display/touch module bonding fixtureMechanical$8,000–$15,000

EVT/DVT/PVT engineering builds & NPI managementNPI$120,000–$200,000
Firmware/software compliance & QA passNPI$40,000–$70,000
Total est. first-run tooling & NRE~$306,000–$538,000
Biggest estimate risk: EVT/DVT/PVT build cost swings hardest on how many design-iteration cycles the enclosure and thermal solution need — this figure assumes typical handheld-class iteration, not a clean first pass.
05

Volume Price Curve

The $96.80 figure in the architecture doc is explicitly low-volume. SoC, display module, and battery cell — the three line items flagged there as highest pricing risk — are also the three with the steepest volume discounts.

Order volumeEst. unit BOMvs. low-volume baseline
1,000 units$96.80Baseline
10,000 units~$84.00−13%
50,000 units~$74.00−24%
100,000+ units~$68.00−30%
This curve assumes Path A silicon pricing holds flat with volume (catalog parts, not a custom die) — if Path B ever ships, the KX2 line item would carry its own separate volume curve tied to wafer/mask amortization, not this table.
06

NPI Timeline & Phased Rollout

Standard four-gate hardware NPI process, sequenced so tooling commitment happens only after the SteamOS POC has validated the launcher/suspend/controller UX this whole plan is building toward.

Gate 0
EVT
~2–3 months
Engineering validation on hand-built units; soft tooling only
Gate 1
DVT
~3–4 months
Hard tooling commissioned; design frozen against certification targets
Gate 2
PVT
~2–3 months
Production-line trial run; certification submissions finalized
Gate 3
MP
Ongoing
Mass production ramp against the volume curve in §05
Sequencing note: DVT's hard-tooling commitment (§04's largest line item) is the point of no return for a design change. It should sit after the SteamOS POC's UX validation, not before — that's the whole reason the POC doc targets existing SteamOS hardware instead of waiting on Kestrel's own silicon.

Recommendation

Silicon
Plan the first production run on Path A (off-the-shelf ARM SoC). Treat Path B (custom KX2 tape-out) as a later-stage decision gated on volume/funding, not a prerequisite to starting CM conversations.
CM selection
RFQ boutique handheld ODMs first (§03) — Kestrel's BOM and expected order size fit that tier, not a Tier-1 EMS.
Sequencing
Don't commit hard tooling (DVT, §06) until the SteamOS POC has validated launcher/suspend/controller UX — hard tooling is the expensive line item in §04 and the hardest to walk back.
Scope note
All figures here are engineering estimates for planning purposes, same caveat as every cost figure elsewhere in this project — not a costing to order tooling against.
