RuiXIN provides embedded flash storage for electronics manufacturers, embedded hardware developers, PCBA factories and equipment OEMs that need compact storage mounted directly to the circuit board. The current portfolio combines BGA NAND flash in 64GB, 128GB, 256GB and 512GB capacity groups with SD NAND products for systems using an SD or SDIO-based architecture.
Instead of selecting memory by capacity alone, your team can compare the host interface, package footprint, workload, environmental conditions, assembly process and production forecast before requesting samples. RuiXIN supports product development, manufacturing, wafer testing and finished-device verification, helping buyers coordinate technical evaluation and commercial sourcing through one project.
Soldered-down storage removes the card slot or drive connector from the finished device. This can reduce occupied space, prevent accidental removal and support a more integrated enclosure. However, the storage component becomes part of the PCB design, so interface compatibility, footprint, firmware behavior and product availability must be reviewed before layout release.
Use the following questions to define your project:
Which storage interface does the MCU, SoC or processor support?
How much PCB area and package height are available?
Is the storage used for boot files, firmware, operating-system data, logs, media or AI models?
How much data will be written per day?
Will the product run continuously or experience frequent power cycling?
What operating temperature and environmental conditions must it withstand?
Does the device require field replacement, or should storage remain permanently installed?
How many years will the equipment remain in production?
What sample, pilot-run and repeat-order quantities are expected?
These answers determine whether BGA NAND flash or SD NAND is the more practical starting point.
These capacity options are intended for compact devices that need more onboard capacity than low-density firmware storage but do not require a removable card or separate solid-state drive. They can be evaluated for smart terminals, industrial gateways, edge devices, embedded computers and other space-constrained electronics.
The public product specification identifies 64GB and 128GB capacity options, soldered-down BGA construction and a 0–70°C operating range. Final interface, package, NAND selection and qualification requirements should be confirmed against the project datasheet before PCB approval.

For equipment storing a larger operating system, application packages, local databases, images or offline data, the higher-capacity BGA range provides a PCB-mounted alternative to removable media.
The key purchasing question is not simply whether 256GB or 512GB is available. Your engineering team must also determine whether the interface, package, sustained workload and thermal conditions match the intended design.
Before sample approval, define:
Expected usable capacity
Host interface
Package dimensions
Read/write workload
Soldering process
Operating temperature
Product lifecycle requirement
Repeat-order configuration

SD NAND combines NAND flash, a controller and firmware in a surface-mount component. It is designed for hosts that communicate through an SD, SDIO or compatible SPI architecture, allowing the device to access storage as a managed block device without relying on a removable TF card slot.
This option is relevant to MCU-based products, smart appliances, printers, monitoring devices, compact controllers and IoT equipment. It can be especially useful when the development team wants permanent PCB integration while retaining a familiar SD-style host interface.
Capacity, package, pin definition, operating mode, voltage and boot support must be verified with the host platform before layout release.
The two product families should not be treated as interchangeable solely because both are soldered to a PCB.
Your platform supports the required BGA storage interface.
The project needs one of the 64GB to 512GB capacity groups currently represented in the RuiXIN range.
PCB area is limited and an integrated storage package is preferred.
The equipment needs onboard storage for larger system or application data.
Your engineering team can qualify the package, interface and firmware configuration.
The MCU or SoC supports SD, SDIO or a compatible SPI mode.
You want to replace a physical memory-card slot with a permanent component.
The project prioritizes simpler block-device integration.
The storage is used for firmware, configuration, logs or local records.
A compact surface-mount package fits the board architecture.
Choose a TF Card when data must be removable, replaceable or transferred outside the device.
Choose an SSD when the host supports SATA or NVMe and the system requires a standard drive architecture, serviceable installation or a different capacity and performance profile.
A benchmark screenshot alone is not an adequate acceptance standard. The test plan should reflect the function of the finished device.
Depending on the project, evaluation may cover:
Electrical and functional screening
Capacity verification
Read/write operation
Host recognition and boot testing
Full-capacity or defined-pattern writing
Power-cycle testing
Continuous or repeated workload testing
Environmental adaptability
Sample-based reliability evaluation
Finished-product inspection
Batch identification and test records
RuiXIN states that its testing services can be planned around functional, performance, environmental and reliability requirements. Its wider business also includes IC packaging, wafer testing and finished-chip testing, supporting communication between product, manufacturing and quality teams.
RuiXIN focuses on memory-related products alongside IC packaging, wafer testing and finished-chip testing. Buyers can discuss the component, assembly route, sample verification and production requirements as one coordinated supply project.
The service structure covers requirement analysis, product development, prototype evaluation, manufacturing and testing. This supports OEMs that need technical review before issuing a volume purchase order.
Small-batch trial production and larger manufacturing arrangements can be discussed according to the project. A pilot stage can be used to establish assembly, testing and acceptance procedures before production is scaled.
The current BGA range is organized around 64GB/128GB and 256GB/512GB options, while SD NAND provides another architecture for SD/SDIO-based devices.
RuiXIN’s manufacturing information emphasizes control from incoming materials through production and finished-product inspection. Buyers can convert these capabilities into project requirements covering identification, testing, traceability and nonconformance handling.
Not always. Embedded NAND flash is a broad description.
Raw NAND normally requires the host system to manage functions such as error correction, bad-block handling and wear management. A managed storage component integrates a controller and firmware to perform some or all of these functions internally.
Confirm the interface and management architecture of the selected part rather than relying only on the product-category name.
It can replace a removable card in designs where the host interface is compatible and field removal is unnecessary.
The PCB must be designed for the surface-mount package, and the final host should be qualified with the selected component before production.
Yes. Engineering samples should be evaluated on the intended host, followed by a pilot assembly where practical.
This helps identify interface, layout, reflow, firmware and workload issues before a larger production run.
Testing requirements can be discussed according to the product and application.
