Validation and smart manufacturing
Designs finalized, boards built
Finished-board manufacturing and support are handled by the controlled subsidiary Xeefee Technology (Jiangmen) Co., Ltd., whose functions are application development, volume validation and smart manufacturing. Designs are finalized in Shenzhen, and development output becomes a production board inside one system — cutting the losses that come with hand-offs between parties.
Finished boards built to the design
Finished boards are produced as the board that matches the design: we build the boards for our own drive and control designs, and we also build to the customer's own design. Form factor, size and interfaces follow the application.
- Built to our production-ready BLDC drive and control designs: design and board come from one system, so interfaces and firmware match
- Built to the customer's own design: the customer supplies design files and material requirements; we take on manufacturing and volume validation
- Control boards and drive boards as a set: delivered as a control board, a drive board, or a combination, as the application requires
- PCBA capability: placement and assembly capability in-house, supporting board-level delivery
Jiangmen plant: turning development output into boards
Algorithms and fundamentals, supply chain and commercial contact are in Futian, Shenzhen; application development, volume validation and smart manufacturing are in Jianghai, Jiangmen. The division between the two sites is clear, and once a design is finalized it goes straight into volume validation and smart manufacturing.

From design files to shipment
Reliable board delivery depends on every stage being properly joined. The table below lists the stages of a typical manufacturing flow and the role we play at each.
| Stage | Content | Note |
|---|---|---|
| Design file confirmation | Schematic and Gerber review, DFM confirmation | Design review fed by manufacturing experience, to cut the number of board revisions |
| Material organization | Materials assembled complete to the BOM, matched under manufacturer authorization | Authorized brands by part number range: see Electronic components |
| Placement and assembly | PCBA production | SMT placement and the following DIP assembly are handled by the Jiangmen plant |
| Functional test | Functional and performance testing against the design targets (FCT) | Tested item by item and recorded; scope is set out in the Validation section |
| Volume validation | Pilot Run → parameter calibration → stability verification | Trial production and validation are carried out at the Jiangmen plant |
| Shipment and traceability | Outgoing quality control (OQC), lot records | Inspected and recorded to process, with Lot Traceability support |
Validation during application development
Validation during application development covers four areas: functional performance, reliability, safety compliance and electromagnetic compatibility. Tests follow national and industry standards, and are executed and recorded item by item under a controlled test process, to confirm the product's function, performance and long-term reliability.
Functional performance testing
Confirms that function and performance meet the design targets.
Reliability testing
Stability under environmental stress and long running periods.
Safety compliance testing
Verification of electrical safety items.
EMC testing
Verification of emission and immunity items.
Standard laboratory and test equipment
The Jiangmen plant has a standard laboratory and the related test equipment to support the four areas above, including but not limited to:
- Temperature and humidity chamber: reliability verification in temperature and humidity environments
- EMI shielded room: shielded environment for EMC testing
- Hipot tester: verification of safety items such as insulation withstand voltage
- Lightning surge tester: immunity verification against lightning surge
- ESD tester: immunity verification against electrostatic discharge (ESD)
- Voltage dip tester: immunity verification against voltage dips and short interruptions

Prototype, Pilot Run and volume manufacturing
Choose the pace to match the stage your project is at. Any stage can be taken on separately, or carried through to volume manufacturing.
Prototype
Sample boards built to our design or to the customer's design files, with support for functional verification and parameter calibration.
Pilot Run
Moves into pilot production to verify batch consistency and process stability, and to fix the process parameters for volume.
Volume manufacturing
Volume production to the confirmed process and materials; the matching components are supplied under manufacturer authorization.
