Why buyers send box build work here
It comes down to the match: factories that fit your product, from the first quote.
Matched by specialisation
Your RFQ goes to up to 3 Vietnamese EMS factories whose declared capability fits, picked for scope, PCBA class, test requirements and volume. Not a general directory.
Professional suppliers
Factories in the network quote to your BOM and drawings, communicate clearly and keep you updated while your product is built.
You deal with the factory
Quotes, terms and delivery are agreed between you and the factory. Free for buyers.
Full electronics box build, scoped to your product
From a single PCB plus enclosure to a multi-module finished unit with cables, displays and packaging. These are the work packages Vietnamese box build factories typically take on. Your RFQ tells us which ones you need, so we only match factories that do them in-house.

- Mechanical fit verification before scale-up
Cable, wire harness and display
- Custom cable assemblies with crimp and connector matching
- Wire harness routing and labelling
- LCD, OLED and touch panel integration
- Speaker, antenna and sensor sub-assembly
Final test and calibration

- Burn-in cycles for power and thermal validation
- Calibration data logging with serial number tracking
- FCC, CE and RoHS pre-compliance test support

Three steps from your BOM to factory quotes
boxbuildvn.com is an independent matching service, not a factory. We find the factories that fit your RFQ. You keep the relationship, the negotiation and the contract.
Send your RFQ
Share your BOM, mechanical files, test requirements and target volume through the RFQ form. Ask for an NDA first if your files are sensitive.
Get matched
We review the scope and match it with up to 3 Vietnamese EMS factories whose declared capability fits: PCBA class, cable work, test, certifications and volume. Reply within 24 business hours.
Work with the factories directly
You receive the factory contacts, request quotes and samples, and negotiate terms yourself. No commission on your order and no middle layer in your communication.
What a box build project with a Vietnamese factory typically looks like
Once you are in contact with the matched factories, most projects follow these five stages. You can see progress through reports, photos and samples without flying in.
Brief and BOM review
The factory maps technical scope and red flags from your bill of materials, mechanical files and target volume before quoting.
Shortlist
You compare up to 3 matched factories on certifications, capacity and experience with similar products.
Quote and sample
Factories quote on the same basis (FOB or DDP) so you compare like for like, then build a working sample for approval.
Production and QC
In-line inspection, AOI checkpoints and final unit test. Ask for regular WIP reports and your own pre-shipment inspection.
Pack and ship
Custom retail packaging, serialisation, freight booking and customs paperwork, delivered to your warehouse or 3PL.
What to send so factories can quote
The more complete the package, the faster the match and the closer the first quotes are to the final price. Missing items are fine at concept stage: say what you have and we match factories that offer DFM support.
| Item | Why it matters | Typical format |
|---|---|---|
| Bill of materials | Drives most of the unit cost and lead time | Excel or CSV with MPNs, quantities, approved alternates |
| PCB data | Needed for PCBA quote and DFM review | Gerber or ODB++, pick-and-place, assembly drawing |
| Mechanical files | Enclosure tooling and fit checks | STEP for 3D, PDF or DXF drawings with tolerances |
| Cable and harness drawings | Wire gauge, connectors and lengths set the harness price | PDF drawing with pinout and labels |
| Test requirements | Fixture design and test time per unit | Test spec or current test procedure |
| Workmanship class and certifications | Filters the factories that can build it | IPC-A-610 class, ISO 13485 or IATF 16949 if needed |
| Volumes and timeline | Matches you with factories of the right size | First order, annual volume, sample date |
| Packaging and shipping | Complete landed-cost comparison | Retail box spec, Incoterm (FOB or DDP), destination |
Why brands move box build to Vietnam
Vietnam is no longer only a backup location. It is a primary EMS hub for brands diversifying away from concentrated supply chains.
Trade access
Vietnam has normal trade relations with the US and free-trade agreements with the EU, UK, Japan and Korea, and is part of CPTPP and RCEP. Duty depends on the HS code and origin rules at the time of import, so check the current rate for your product.
Mature EMS cluster
Samsung, Foxconn, Pegatron and Luxshare run large plants in Bac Ninh and Hai Phong. The supplier base built around them also serves SMEs and mid-volume brands, with a second cluster around Ho Chi Minh City, Binh Duong and Dong Nai.
English-speaking project management
Project managers and QC engineers at export-oriented factories work in English. Engineering change orders and daily updates reach your inbox without translation lag.
Product categories Vietnamese box build factories handle
Each RFQ is matched to factories with a track record in that product family, not a generic EMS. Tell us the category and any compliance target in your RFQ.
Build content, standards and production tests by product type: box build applications.
- IoT gateways, smart-home hubs and Wi-Fi mesh nodes
- Industrial controllers, PLC enclosures and edge gateways
- Consumer audio: speakers, soundbars and headphones
- Battery-powered devices: trackers, wearables and scanners
- Display modules: digital signage, kiosks and POS terminals
- Medical-adjacent (non-FDA) wellness and fitness devices
Tell us about your box build project
Send your BOM and product brief. We come back within 24 business hours with up to 3 matched factories. No commitment and no fee. All inquiries are kept confidential, NDA on request.

Common questions before starting a project
What is electronics box build assembly?
Box build (also called systems integration) is the full assembly of a finished electronic product: PCBA, enclosure, cables, displays, power supply and final test combined into a packaged unit ready to ship. It is one step beyond bare PCBA and one step before consumer fulfilment.
How does boxbuildvn.com work?
You send one RFQ with your BOM, drawings and test requirements. We match it with up to 3 Vietnamese EMS factories whose capability fits and reply within 24 business hours. You then contact, quote and contract with the factories directly.
What does it cost the buyer?
Nothing. Sending an RFQ and getting matched is free for buyers. Factories pay for the matched RFQs they choose to receive. We take no commission on your order.
Why source box build from Vietnam instead of China?
Vietnam gives China-plus-one risk diversification, labor costs below coastal China and export-oriented factories with English-speaking project management. Duty depends on the HS code and origin rules, so check the current rate for your product. Lead times are typically 4 to 8 weeks for full box build orders of 500 to 10,000 units after sample approval.
Do I need to fly to Vietnam to vet factories?
Not for a first review. Factories typically provide video walkthroughs, certificate copies, equipment lists, sample units and inspection reports, and you can hire an independent third-party inspection company. Many buyers visit before the first production order or once volumes grow.
What are typical minimum order quantities?
Vietnamese EMS factories commonly accept runs from about 100 units for prototype-to-production work, and larger plants scale to 50,000+ units per month. Matching takes your volume into account so each factory fits your capacity and pricing tier.
Is my BOM and design data protected?
Yes. Tick the NDA box on the RFQ form and we sign an NDA before your BOM or design files go to any factory. Files are only shared with the factories you approve.
Are you a Vietnamese EMS or box build factory?
Register your capability to receive box build RFQs from OEMs that already have a BOM, drawings and a clear volume. You choose the RFQs you want.
Components, PCB, cable, test and SMT equipment
Authorised distributors and equipment suppliers that serve Vietnamese EMS factories can register as partner suppliers.
