Choosing Micro SD Memory Suppliers
When it comes to memory options for small devices, microSD (sometimes called micro SD) is a common solution. This flash memory format is powerful but tiny, providing high-quality memory in devices in which space is at a premium. Different micro SD memory suppliers should all follow the design specs set by the Secure Digital Association. Anyone who makes SD cards is required to follow these guidelines in order to ensure that there is a reliable design and operation standard across all cards. However, the supplier you choose still matters. Here are some things to look for when choosing a microSD memory supplier.
Grade of microSD Cards
All microSD cards provide reliable storage, but not all cards are appropriate for all operations. If you have an industrial application, then you need a microSD card that is industrial grade—which is something not all suppliers can provide. With an industrial microSD memory card, you get a card with a higher tolerance for shock and vibration, along with an extended operating temperature range. Since many industrial applications are used in rugged operating environments, cards that are not designed to meet industrial conditions will be prone to failure. Industrial microSD cards have SLC, or single-level cell, flash memory, which means that only one bit of data is stored per cell. This further increases the reliability and lifespan of the microSD cards, which is essential for devices used in critical industries, such as healthcare or transportation.
Locked Bill of Materials
For engineers and OEMs, long-term reliability of memory is important. An unexpected change in the design of a memory card could cause far-reaching device failures that affect users in the field. A locked bill of materials, or locked BOM, ensures that no critical component of the microSD card will be changed by the supplier without advanced notification. This ensures that customers can place a final order of the existing card design. A new product number will be issued for any card when there is a critical design change, preventing misunderstandings that could lead to device failures.
The ability to customize microSD cards is important to OEMs and is not something that is offered by every supplier. Choose a micro SD memory supplier who can provide the customizations you need, from pad printing and packaging to special testing and unique data loading.
