Electronics contract manufacturing, from bare board to boxed product
Four SMT lines, component distribution and trading, cable and harness, injection moulding and box build — under one roof in Hangzhou, shipping to more than 80 countries.
Four businesses, one supply chain
Most customers start with one and end up using all four. That is the point — you should not have to manage four suppliers for one product.
Manufacturing
PCBA assembly under OEM or ODM engagement — SMT, DIP, test, box build.
Capabilities →Products & distribution
Electronic components, PCB connectors and custom cable assemblies.
Browse lines →Tooling & moulding
Mould making and injection moulding for small precision parts and housings.
Moulding service →One supplier, one schedule
From BOM to boxed product, with one project manager across all four lines.
How it works →We do not only build other people's designs
Two finished-product lines are developed and made here: GaN USB-C chargers, and industrial instruments that measure and record. Either can carry your brand instead of ours.
Four things that decide whether a programme ships on time
Certified quality system
ISO 9001 and IATF 16949, IPC-A-610 Class II/III workmanship, ANSI/ESD S20.20 protected lines.
Lot-level traceability
Material lots, process parameters and test results tied to each batch — not reconstructed afterwards.
A quote in 24 hours
An engineer reviews your BOM and Gerber before pricing. DFM problems are flagged before tooling, not after.
One point of contact
Board, components, cable, enclosure and packing handled by one project manager, not four vendors.
Built for high-mix work, not just long runs
Four automated SMT lines handle anything from a five-piece prototype to volume production. High-mix, low-to-mid volume is our normal operating mode — it is why we can quote a 20-piece build without asking you to commit to 5,000.
| Parameter | Range |
|---|---|
| Board size | 45 × 45 mm to 450 × 500 mm |
| Layers | 1–20 |
| Minimum component | 01005 |
| Minimum pitch | 0.2 mm |
| Max BGA ball count | 256 |
| Printing accuracy | 0.025 mm |
| Reflow | Ten-zone oven, 300–2,000 mm/min |
| Conformal coating | Up to 200 µm |
This is the line your board actually runs on
Photographs from the floor in Hangzhou — placement, inspection and material handling, in the same building as the people who quote your job.
Five checkpoints between your files and your shipment
Every board follows the same route. No sampling on final test, no silent shortcuts.
Incoming inspection
Components verified on arrival — specifications, lot traceability, labelling and storage conditions recorded before anything reaches the line.
Solder paste inspection
3D SPI measures paste volume, height and offset in real time, so a bad print never reaches placement.
Placement and reflow
01005 to BGA placement, then reflow in a ten-zone oven on a recorded profile. Nitrogen is available for fine-pitch and BGA work, where low oxygen keeps voiding down. AOI checks every board as it leaves the oven.
X-ray inspection and CT
Hidden joints on BGA and QFN measured on a microfocus X-ray CT (SEAMARK X-6600) — void percentage, wetting and solder-ball integrity, reports on request. Reels are also counted by X-ray on receipt.
Outgoing QA and functional test
Final audit, firmware loading, ICT or FCT as required, then packing with full lot records.
Three things you can hold us to from the first order
Not a mission statement — the three commitments that decide whether a programme runs smoothly, written into how we work rather than promised per project.
Boards we build, and where they end up
The two questions every first order comes down to
Whether the money can move safely, and how the goods actually arrive. Both are answered here, before anyone sends a file — so the commercial side is never the reason a project stalls.
Payment
- T/T 30 / 7030% deposit to release material, 70% before shipment. The default for series production.
- T/T in advanceSamples and small orders, where a bank charge would be a real share of the invoice.
- L/CLarger programmes. Terms and issuing bank confirmed before the order is booked.
- PayPal / Western UnionSmall samples and one-off buys, where a company card is easier than a transfer.
Shipping
- ExpressDHL, FedEx or UPS. Samples and small series, door to door, tracked from the day it leaves.
- Air freightVolume orders that cannot wait for a sailing. Airport to airport.
- Sea freightLCL and FCL for full runs — scheduled backwards from your line date.
- Your forwarderWe deliver to the warehouse you nominate and hand over the documents.
