About Loongtion
In-house industrial memory & SSD — Xi'an QA, Ningbo shipment
Who We Are
Not a trader — we design, screen, and stand behind every program we release
Loongtion (龙瑆)
Loongtion owns industrial-grade storage programs — memory chips, SSDs, and modules for control, edge, and embedded systems in wide-temperature enclosures.
We design and test in-house; we do not relabel consumer parts as industrial.
In-house design — one quality chain from spec to shipment
Xi'an since 2015 · Ningbo commercial hub est. 2024One chain from Xi'an (Yizhuo) engineering and QA to Ningbo (Loongtion) shipment — BOM review, samples, and production on the same inquiry thread.
Remote review covers pinout, footprint, and incumbent part numbers before you commit.
Markets we serve
Programs that need wide temperature, documented NAND, and field endurance — telecom edge, SCADA, factory automation, IPC, energy, and transportation.

How we work with your team
Direct engineering, documented specs, and screening before release — not retail packaging
One team from inquiry to shipment
Email BOM, drawings, or incumbent part numbers — we reply on your thread with PDF datasheets and quotations (usually within 24 hours Mon–Fri UTC+8). Same engineers own fit review, sample support, and production release. Large or small programs receive the same care; we do not turn away low-MOQ inquiries when a line is in scope.
Why procurement and design teams work with us
Product owner, not a broker
In-house design with materials, firmware criteria, and release testing under our control — built for industrial temperature and endurance, not desk retail repackaging.
Xi'an QA & ISO9001
Electrical and environmental screening before release; GB/T 19001-2016 / ISO 9001:2015 quality system and in-house test capability at Yizhuo (Xi'an).
Industrial WT & Industrial Ext
Wide-temperature grades for cold outdoor starts, sealed hot cabinets, factory edge heat, and transport thermal cycles — not unlabeled 0–70°C consumer parts.
Remote BOM & drawing review
Pinout, footprint, memory map, and incumbent PN cross-check — free first step on your inquiry thread before you commit to samples or bulk.
Published endurance where it matters
TBW on M.2 NVMe, SLC on SATA DOM, pSLC/TLC tiers on eMMC and NVMe BGA — specs you can plan qualification around.
5-year B2B warranty
Five-year warranty on industrial M.2 NVMe and SATA DOM SKUs; 5-year free-replacement program on qualified bulk memory-chip orders under normal operating conditions.
Engineering deliverables
Datasheets & design-in packs
Full PDF datasheets (timing, package, ordering info, environmental grades), pad dimensions, MSL, and reflux guidance per line.
Qualification support
Sample quantities typically 1–5 pcs per PN for socket fit, burn-in, and platform validation before bulk commitment.
Built for field duty
Reliability is what we test before release — not a line on a consumer label
Wide temp · durable · stable
Operating −40°C to +85°C (Industrial Grade I) on SSD lines; Industrial WT and Industrial Ext on memory chips where listed. Storage −45°C to +90°C per datasheet. Programs that run 7×24 in outdoor cabinets, telecom edge, and industrial IPC cannot gamble on undocumented NAND or missing TBW.
Compliance & design standards
JEDEC-aligned DDR3/DDR4/DDR5 and LPDDR4X; eMMC 5.1 (JESD84-B51.1); NVMe 1.4; RoHS-aligned, lead-free designs. Civilian industrial and infrastructure use — not marketed for military or defense end-use.
Three pillars behind every release
The same structure we document on our industrial M.2 NVMe and SATA DOM programs applies across the portfolio.
In-house storage programs
Materials selection, firmware criteria, release testing, and direct engineering — for industrial temperature and endurance, not consumer shelf life.
Xi'an screening before dispatch
Lot screening and environmental test in Xi'an; ISO9001-backed incoming and release procedures before Ningbo shipment.
Direct engineering access
Firmware review, incumbent cross-reference, durability planning, and field-issue follow-up by email — hi@loongtion.com on your project thread.
Registration, IP & quality documentation
Loongtion and Yizhuo program credentials — full copies included in your quotation pack on request.
Business registration & enterprise recognition
ISO9001, trademarks & patents
What you can expect
Every released SKU is backed by documented specs, screening before shipment, and engineers who own the program.
Documented specs, not marketing adjectives
Temperature grades, NAND type, TBW, connector/part numbers, and ordering tables in PDF datasheets — the same detail we publish on our industrial memory chips, M.2 NVMe, and SATA DOM programs.
5-year warranty on industrial SSD programs
All industrial M.2 NVMe and SATA DOM SKUs carry a five-year warranty; qualified bulk memory-chip programs include a 5-year free-replacement plan under normal operating conditions (non-human damage).
Credentials on request
