Flash Memory Procurement

In short

This section covers the buying decision rather than the product: how to choose and verify a manufacturer, what to put in an RFQ, how MOQ and lead time are set, what a purchase specification and acceptance agreement should contain, and the checklists and tools to act on it. Everything here works on any supplier, including us.

Product Selection

How to choose a manufacturer

Six questions that separate a factory from a catalogue.

TF vs USB vs UDP

A decision guide by how your product receives storage, not by the marketing label.

Technical Specifications

Specify a TF card

The six lines that decide what you actually receive.

Specify a UDP module

What a designer has to fix before a UDP module can be quoted.

Specify a semi-finished board

The board-level decisions that change the price and the schedule.

Write a purchase spec

The clauses that keep batch two like batch one.

Quality Testing

Acceptance agreement

Turn 'it should be fine' into test criteria both sides sign off on.

OEM/ODM and Customization

Custom USB RFQ checklist

Specify housing, branding, interface and packaging so a custom USB quote is firm.

MOQ, Samples and Lead Time

How MOQ is set

Why there is no single MOQ, and what actually sets yours.

Samples

What a sample tells you that a datasheet cannot.

Production lead time

What the clock actually depends on, and where orders slip.

Cost and Repeat-Order Control

What affects the price

Seven variables — and why the NAND market moves all of them.

Repeat orders

What to lock in writing so the next order matches the last one.

Compare supplier quotes

Put two quotes side by side on grade and spec — not on the headline number.

Supplier Evaluation

How to verify a supplier

A checklist you can run in a day, on any supplier — including us.

RFQ and Incoming Inspection

What to send for a quote

The same list we work from — send it once, get a firm price.

TF card RFQ checklist

Everything to put in a TF card enquiry so the quote is firm, not a placeholder.

Bulk order acceptance

Agree these acceptance points before production, not after the goods arrive.

Interactive tools

Calculators and checklists you can use right now — estimate a TF card capacity, build a copy-ready USB specification, or record a sample acceptance result.

Frequently asked questions

What information do you need before you can quote?

Five things: product type (card, UDP module, USB drive or semi-finished board), capacity, quantity, branding requirement and the date you need the goods. Anything missing is asked back rather than assumed, because a quote built on assumptions usually changes later.

How can I compare quotations from several suppliers fairly?

Put every quote on the same basis: same Incoterm, same capacity and NAND grade, same packaging, same test scope, and a stated quotation validity period. A lower unit price with a different grade or a shorter validity is not the same offer.

Do you supply samples before a bulk order?

Yes. Samples are produced and approved before bulk production, and what to test on the sample is agreed in advance — capacity verification, read and write speed, print quality and packaging. Bulk production starts only after the sample is signed off.

What documents come with a shipment?

Commercial invoice, packing list and a certificate of conformance as standard. Test reports and material declarations are available on request, and any document your customs broker needs should be named before the order is confirmed rather than after.
