UDP Module Manufacturer in China — Embedded Flash Modules

In short

WINTEL is a UDP (USB Disk in Package) module manufacturer, not a trading company. A UDP module is the electronic core of a USB flash device — NAND, controller and passives moulded into a single package that is soldered directly onto your PCB as fixed internal storage. We produce them on our own floor in Shenzhen, China, at 11.3 × 24.8 × 1.45 mm and 0.819 g, from 128MB to 128GB, for embedded and industrial device makers who need storage that enumerates reliably and survives without a separate connector. Capacity, silicon grade, controller solution and testing are set to your specification. The legal entity is Shenzhen Wintel Digital Technology Limited, registered in China since 2015.

What we manufacture

UDP modules (USB Disk in Package)

11.3 × 24.8 × 1.45 mm · 0.819 g · 128MB–128GB

Soldered onto your own PCB as fixed internal storage — no connector, no loose drive.

Semi-finished USB boards

12 × 44 × 4.5 mm · 3.2 g · 128MB–128GB

The bare PCBA when you run your own housing or final assembly.

Finished USB flash drives

Metal, PVC or wood body · 128MB–128GB · USB 2.0 / 3.0

When you need the complete drive rather than the embedded core.

Who we supply

Embedded device manufacturers

You design the board and need a storage core that solders in place and enumerates the same way on every unit — dashcams, IP cameras, POS terminals, kiosks, medical and industrial controllers.

Industrial equipment manufacturers

You need fixed storage that is not a removable consumer drive — no card slot to loosen, no connector to corrode, no user pulling the wrong media.

IoT and appliance makers

You ship firmware, logs or configuration on a core that is part of the product, not a peripheral the customer swaps.

Assembly lines and integrators

You take the UDP or the semi-finished board and run your own housing, conformal coating or final test.

Manufacturer versus trading company — what actually differs

Factory-direct (WINTEL) Through a trading company
Where the specification is set On our own floor — capacity, controller, silicon grade and testing are configured against your order. By whichever factory takes the order that week.
What happens when material is short You are told before a substitution is made, because the silicon and controller are documented in the specification we quote. Substitution happens between you and the end factory, usually without notice.
Who owns the quality check Capacity and read/write verification run as part of our own production flow, before packing. Whatever the supplying factory did, which you cannot audit.
What you can ask to see The process, the test method and the registration record of the legal entity you are contracting with. A catalogue.

Frequently asked questions

Are you a UDP module manufacturer or a trading company?

A manufacturer. Shenzhen Wintel Digital Technology Limited produces UDP modules on its own floor in Shenzhen. We are not a reseller, a distributor or a marketplace seller.

What is a UDP module, exactly?

UDP means USB Disk in Package — NAND, controller and passive components moulded into one small package (11.3 × 24.8 × 1.45 mm) that is soldered onto your PCB as fixed internal storage. It is the core of a USB drive, without the connector and housing.

What capacities do your UDP modules cover?

From 128MB to 128GB. Tell us the device the module must serve and we size the capacity and grade to that workload rather than defaulting to a single option.

How do you keep the module consistent across batches?

Capacity, silicon grade, controller solution and testing are stated on your quotation and held as quoted through production. A shortage becomes a conversation before any substitution, not a surprise on arrival.

Can you provide the semi-finished board instead of the UDP?

Yes. The semi-finished USB board (12 × 44 × 4.5 mm) is the bare PCBA for buyers who run their own housing or final assembly. The UDP is the moulded core for buyers who solder directly.

Which silicon and controllers do you use?

SanDisk, Toshiba, Micron, SK Hynix, Intel, Samsung, in TSOP, BGA, LGA, COB and eMMC formats, at A+ grade, with controllers from Alcor, ITE, Xinbang, Micov. We are not an authorised agent for any NAND brand — we buy and sort flash and state the grade and source against your project.

Do you have certifications?

We list only certifications we hold and can show documentation for. Where a certificate is not yet published on our site, we do not claim it.
