Component sourcing & BOM engineering
Cross-checked alternates, lead-time-aware BOMs, and direct relationships with authorised distributors and second-tier specialists across the Pearl River Delta.
Hardware Technology / Est. Hong Kong
Engineering the quiet hardware behind ambitious products.
Queen Lee partners with founders, OEMs, and global product teams to source components, industrialise prototypes, and deliver electronic assemblies that ship at scale — measured, repeatable, and built on a network we've spent a decade refining.
A small, deliberate set of capabilities — practiced for a long time.
We don't try to do everything. We do the work upstream of mass production well, then we stay close while your product moves through manufacturing, testing, and shipping.
OEM & ODM partnership
From schematic review through DFM, tooling, pilot run, and ramp — a single team accountable for both engineering and the factory floor.
Compliance & test programmes
CE, FCC, RoHS, UN38.3 and IEC test routing, plus on-site burn-in, AOI, and outgoing audit by inspectors who actually understand your product.
Logistics & bonded warehousing
Hong Kong as your free-port hub: consolidation, kitting, and worldwide forwarding — with bonded inventory you can call off as orders land.
Prototype to production
We turn working prototypes into things factories can actually build — yield-tuned, cost-tuned, and documented to a standard that survives turnover on the line.
Programme management
One programme manager, weekly written status, no surprises. We make hardware schedules legible to founders, finance, and the engineers actually building it.
Numbers that describe how we work — not how we sell.
Hardware programmes live or die on lead time, defect rate, and how quickly issues travel from line to engineer. These are the metrics we track for ourselves.

How a programme moves through Queen Lee.
The work is not glamorous, but it is precise. Here is the path most projects take — from first call to first shipment.
-
step / 01
Brief & technical scoping
We read the schematic, the BOM, and your roadmap. We come back with the two or three things that will actually move cost, schedule, or yield.
-
step / 02
Sourcing & DFM review
Quotes against three sourcing strategies, with stocking risk surfaced. DFM notes returned within 10 working days, in the original CAD package.
-
step / 03
Pilot run & qualification
Small builds (50 — 500 units) to qualify process windows, fixturing, and test coverage before tooling steel is cut.
-
step / 04
Ramp, ship, sustain
Production with weekly written status, defect Pareto, and a sustaining engineer who answers your messages — not a generic mailbox.
Have a brief that should have shipped six months ago?
Send it. We'll read the BOM, the schematic, and your last three change orders, and tell you honestly whether we're the right partner. No deck, no slide-by-slide.
