This page sets out how a first order runs with HGCHIPS: what the sample quantity is, what ships with it, how long stock and non-stock lines take, and what to send us to get a usable answer. Samples and lead times apply to the memory and power lines we carry: DDR3 (1.35 V / 1.5 V, VFBGA-96), DDR4 (1.2 V, FBGA-78/96) and LPDDR4 / LPDDR4X (up to 4266 MT/s, VFBGA-200), plus ADI LTM46xx / LTM80xx µModule drops. State the original part number, target density (for example 8 Gb) and quantity when you request a sample, so the quote can be matched to the correct speed grade and package. At a glance ## The numbers that decide a first order ### Sample quantity **From 10 pcs** — enough for incoming inspection, validation on your platform and a burn-in check ### Sample cost **Credited against your first production order**, so validating before you commit does not add to programme cost ### Stock lines **48h dispatch from Shenzhen** on parts we physically hold ### Quotation **Within 24 business hours**, including the compatibility check ### Lot documentation **Per-lot inspection and validation records**, plus datasheets and compatibility notes for the part number ### Material compliance **SGS / RoHS / REACH** statements where applicable Sequence ## How a first order runs, step by step 1. **Send the exact marking from your BOM**, your monthly usage and the grade you need. The marking matters more than the family name: suffix letters change footprint height, temperature grade or packing, and a substitution that looks right on paper can fail on the board. 2. **We return a compatibility check and quotation within 24 business hours** — the fields compared against the original datasheet, the grade quoted, and the lead time for that grade. 3. **You order samples from 10 pcs.** Sample cost is credited against your first production order. 4. **Validate on your own platform.** Patch measurements and a working prototype are not the same as qualification — test at your temperature extremes and run a burn-in check. 5. **Release production.** Stock lines dispatch in 48 hours from Shenzhen; scheduled shipments and firm pricing are available for long-lifecycle programmes. Documentation ## What you can see before you commit - **A sample test report for your target part number** — ask for it before ordering, not after. - **A live video test on WhatsApp** — watch the qualification run rather than reading a PDF. - **Datasheet and compatibility notes** for the specific HG part number, including the original part numbers it is mapped against. - **Per-lot inspection and validation records** , shipped with the lot — records tied to the lot you actually receive, not a generic certificate. - **SGS / RoHS / REACH statements** where applicable. If a supplier cannot show per-lot records, you cannot know which die revision you are approving. That is the test to apply to us as much as to anyone else. Lead times ## Stock versus non-stock — and why we quote rather than promise Lead time is the one number a supplier cannot honestly generalise. It depends on the part number, the grade, and whether we physically hold the lot. So we split it: | Case | What we state | | --- | --- | | Part held as stock | **48h dispatch from Shenzhen** — quoted from a physical position | | Non-stock, standard grade | Confirmed lead time in the quotation, per part number | | Long-lifecycle programme | Scheduled shipments with firm pricing, so unit cost does not move with the spot market | | Grade not held | We say so and quote the lead time for that grade, rather than offering a different grade | Scope ## What this page does not claim Sample and lead-time terms are indicative until confirmed in a quotation, and they apply to the specific part number and grade quoted. Nothing here replaces the qualification work on your own platform — a delivered sample that boots is not an approved part. FAQ ## Common questions ### What is the minimum order quantity for samples? Sample quantities start at 10 pcs. That is normally enough to run incoming inspection, functional validation on your own platform and a burn-in check, which is the same sample plan described in our qualification checklist. ### Is the sample cost credited against production? Yes. The sample cost is credited against your first production order, so validating before you commit does not add to the programme cost. ### How fast do stock lines ship? Stock lines dispatch in 48 hours from Shenzhen. Non-stock and long-lifecycle quantities are quoted with a confirmed lead time rather than a promise, because the honest answer depends on the specific part number and grade. ### What documentation ships with a sample or a lot? Per-lot inspection and validation records, datasheets and compatibility notes for the specific part number, and SGS / RoHS / REACH statements where applicable. A sample test report can be shared before you order. ### Can I see a test report before committing? Yes. We share a sample test report for your target part number, and you can book a live video test on WhatsApp to watch the qualification run rather than reading a PDF. ### How long does a quotation take? Compatibility check and quotation within 24 business hours. To get a usable answer rather than a catalogue link, send the exact marking from your BOM, your monthly usage and the grade you need. ### What if the grade I need is not in stock? We tell you that rather than substituting something similar. Industrial-grade parts (-40 to +95 C) are held in dedicated lines; where a grade is not held, the quotation states the lead time for that grade instead of offering a different one. ## Request samples or a quote Send the exact marking, your monthly usage and the grade you need — we reply within 24 business hours with the compatibility check and the lead time for that grade.
