Finding a contract manufacturer in China for an AI hardware product

Aslan Sourcing runs AI (artificial intelligence) hardware sourcing as a factory search project, quoted per project: we screen the factories across China that make your kind of device, visit the shortlist, negotiate in Chinese, pull samples and hand you a ready-to-order file. Factory visits, audits and inspections are billed on a day rate with travel at cost, and when we manage an order our commission is 4 to 8 percent of order value, invoiced to you, with nothing taken from the factory side (prices).

Aslan holds no standing partner factory in electronics or AI hardware. Our standing factory relationships today are in brushes and vacuum cleaners, so every shortlist in this category starts from a fresh search.

Four kinds of partner and what each one does

AI wearables, recorders, smart glasses and companion devices are built by partners who split design and production differently. The first question: who owns the design?

• EMS (electronics manufacturing services). An EMS provider builds to your design and often adds supply chain and test services, while the product IP (intellectual property) stays with you, per Escatec’s definitions.
• ODM (original design manufacturer). An ODM “owns the product design and IP and supplies products that clients rebrand” (Escatec).
• Design houses. An IDH (independent design house) performs electronic system design including the PCB (printed circuit board), and may add industrial and software design. Counterpoint Research notes most offer design as part of a wider ODM service.
• Module and chipset vendors. Chip makers work through these partners: MediaTek’s directory groups them as “SOM/IDH/ODM Partners”, SOM meaning system on module. A CE-marked radio module, one carrying the EU conformity mark, comes with its own Declaration of Conformity, while a bare chipset “has no regulatory status of its own” (Element).

Where the clusters are

China Briefing describes the electronics sector as “overwhelmingly concentrated” in the Pearl River Delta, with strengths in smart terminals, communications and chip design. Manufacturers with a presence in Shenzhen include Foxconn (China Briefing), and its component market is covered in our Huaqiangbei guide. The Hong Kong Trade Development Council calls electronic information manufacturing one of Dongguan’s pillar industries.

The same China Briefing overview credits the Yangtze River Delta with a strong base for laptops, semiconductors and mobile phones, and lists Suzhou among its developed chip cities. A China Daily article of 18 December 2025 describes Kunshan, near Shanghai, as home to a trillion-yuan electronic information cluster led by display panels and optical devices. A factory search should cover both deltas.

Build stages: EVT, DVT, PVT and mass production

Formlabs describes the usual sequence:

• EVT (engineering validation test): about 20 to 50 units, often machined or 3D printed, to prove the functions work.
• DVT (design validation test): the contract manufacturer builds the first hard tool for each custom part, and the product goes through testing and certification.
• PVT (production validation test): design and moulds are locked and the line is stabilised. Embedded Artistry sets the exit at acceptable yields and throughput on at least one line.
• Mass production: ramp-up, yield improvement and cost reduction.

NRE, tooling and minimum order quantities

NRE (non-recurring engineering) is the one-time cost of getting a product into production, kept out of the unit price. For a device it covers items such as stencils, jigs and fixtures and a functional test rig for the boards, and moulds for the plastic parts (QualityInspection.org). The MOQ (minimum order quantity) is the smallest order a factory accepts. Ask for both per custom part and for the finished product, and ask how each changes with volume. Tooling ownership is covered on our moulding and machining page.

Protecting your design in China

Harris Sliwoski recommends an NNN agreement (non-disclosure, non-use, non-circumvention), because the larger risk is the factory using your information itself. Sign it with the company that will hold your files. China is first-to-file for trademarks, and a Latin-script registration does not protect a Chinese name (China Briefing). Protection starts on registration and lasts 10 years (European IP Helpdesk).

What to prepare before contacting factories

• BOM with manufacturer part numbers and quantities
• Gerber files, the de facto standard for PCB layer and drill data
• CAD (computer-aided design) models and 2D drawings of the enclosure
• Test specification: what a passing unit must do
• Target unit cost and yearly volume
• EU markets and certifications you need

Vetting an electronics factory

• ISO 9001 certificate found on IAF CertSearch, the International Accreditation Forum database, with a scope that covers assembly. ISO (the International Organization for Standardization) has replaced ISO 9001:2015 with ISO 9001:2026, so note the edition.
• SMT (surface-mount technology) lines running on site
• AOI (automated optical inspection) and X-ray, which images hidden solder joints (Electronic Design)
• IQC (incoming quality control) on components, with named suppliers
• Traceability by lot; the electronics standards body IPC publishes IPC-1782 for this (IPC)
• Export history to Europe, checked as in our supplier verification guide

EU compliance in brief

The RoHS (Restriction of Hazardous Substances) Directive restricts ten substances in all products with an electrical and electronic component, and radio products need their own conformity assessment. Our EU compliance guide for AI wearables and connected devices covers the rest. Before you sign off a device for the EU market, have a lawyer and a test laboratory review it; this page is general information.

Questions buyers ask

Does Aslan already work with an electronics or AI hardware factory? No. We run a factory search project and build the shortlist from scratch.

Should I go to an ODM or an EMS? An ODM saves design time but usually keeps the design unless the contract says otherwise. An EMS builds your finished design and the IP stays with you.

Can a factory quote before my design is final? It can quote early. Expect revisions as the design changes and again when hard tools are made at DVT.

Is a standard NDA (non-disclosure agreement) enough? Lawyers who work on China manufacturing recommend an NNN agreement signed by the factory itself.

What does Aslan charge here? Factory search: quoted per project. Visits and audits: day rate. Managed orders: 4 to 8 percent commission, paid by the buyer. See pricing.
