Flash Memory Manufacturer in China — B2B & OEM/ODM Supply
WINTEL is a flash memory manufacturer, not a trading company. We produce TF cards, UDP modules (USB Disk in Package), custom USB flash drives and semi-finished USB boards on our own production floor in Shenzhen, China, and supply them to importers, distributors, brand owners and device makers on a B2B and OEM/ODM basis. Capacity, interface, read/write speed, silicon source, controller solution, housing and branding are set to your specification rather than taken from stock. The legal entity is Shenzhen Wintel Digital Technology Limited, registered in China since 2015, with the team in this industry since 2006. If you are comparing suppliers, the useful question is not what a supplier claims but what it can show: see our factory pages for the process, the quality checks and the evidence behind them.
What we manufacture
TF cards (MicroSD class)
Printed to your own artwork, supplied in bulk or retail packaging.
UDP modules (USB Disk in Package)
Soldered onto your own PCB as fixed internal storage.
Custom USB flash drives
Silk-screen, colour print or laser engraving to your artwork.
Semi-finished USB boards
The bare PCBA for buyers who run their own housing or assembly.
Every specification on this page is taken from our own product documentation. Where a figure is not yet published, it is marked as to be confirmed rather than filled in with a plausible number.
Who we supply
Importers and distributors
You need a factory that can hold a specification across repeat orders, and that will tell you which silicon you are actually buying.
Brand owners and promotional buyers
You need your own brand on the product and packaging, with the flash inside specified rather than left to whatever module is in stock.
Device makers and OEM/ODM buyers
You need a part that enumerates reliably on your host — dashcams, IP cameras, POS terminals, industrial controllers and embedded devices.
Assembly lines and integrators
You have a housing and a line, and only need the electronic core. Order the UDP module or the semi-finished board instead of a finished drive.

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 branding 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. |
This comparison describes our own operation, not a claim about any named third party.

Request a quoteFrequently asked questions
Are you a manufacturer or a trading company?
A manufacturer. Shenzhen Wintel Digital Technology Limited operates its own flash memory production in Shenzhen. The products listed on our product pages are the ones we produce. We are not a reseller, a distributor or a marketplace seller.
What is the minimum order quantity?
MOQ depends on the product, the capacity, the controller solution and how much customisation is involved. There is no single MOQ figure that honestly applies across every project. Send your specification and we will confirm the MOQ together with the price. See how MOQ is set for the detail behind this.
Can you put our brand on the product?
Yes. Silk-screen printing, full-colour printing and laser engraving on metal, PVC or wood bodies, with presentation boxes and accessories where the product needs to work as a gift. Bespoke moulds are available for a shape based on your own design. See custom branding.
Which silicon do you use?
SanDisk, Toshiba, Micron, SK Hynix, Intel, Samsung, in TSOP, BGA, LGA, COB and eMMC formats, at A+ grade. We are not an authorised agent or distributor for any NAND brand — we buy and sort flash, and we tell you the grade and source against your specific project rather than implying a brand partnership we do not have.
Which controllers do you work with?
Alcor, ITE, Xinbang, Micov, in QFN, 24-pin, 48-pin and COB packages. The solution is selected against your host interface, capacity and required speed, not defaulted.
Do you have certifications?
We list only certifications we hold and can show documentation for. The current published status is on our certifications page — where a certificate is not yet published there, we do not claim it.
Can I visit the factory, or get a video tour?
Yes to both. Our factory page shows the production floor, the test station and the assembly area as they actually are. Tell us when you would like to see more and we will arrange a live walkthrough.
