Compared to traditional SD cards, patch mounted TF cards (also known as SD NAND or SD Flash) have multiple advantages, mainly reflected in size and volume, plug-in durability, seismic and vibration resistance, physical protection, and adaptability to application scenarios. Here is a detailed analysis of these advantages:

　　Size and volume:

　　The patch type TF card is packaged in LGA-8 and has a compact size, typically ranging from 6x8mm to 9x12.5mm, which is much smaller than the size of traditional SD cards. This makes the patch type TF card more suitable for embedded systems or compact devices with limited space, such as smart wearables, portable medical devices, etc.

　　Plug in durability:

　　Traditional SD cards require frequent insertion and removal, which may lead to wear and corrosion of the card slot and socket. Long term use may result in poor contact, disconnection, or read-write errors. The surface mount TF card is directly soldered onto the PCB through reflow soldering process, without the need for a slot, thus avoiding durability issues caused by insertion and removal operations.

　　Seismic and vibration resistance performance:

　　The traditional SD card connection method is achieved through card slots and sockets, which have poor seismic and vibration resistance. In applications with frequent vibrations, traditional SD cards may experience unstable connections or data loss. The patch type TF card, due to being directly soldered onto the PCB, has better seismic and vibration resistance, making it more suitable for harsh environments and applications with frequent vibrations.

　　Physical protection:

　　Traditional SD cards do not have additional protective measures on the outside, such as waterproof, dustproof, and other functions. When used in certain harsh environments, it may be affected by external factors, resulting in data corruption or equipment failure. Some patch type TF cards provide waterproof, dustproof, and anti-static functions to increase physical protection, improve device stability, and durability.

　　Adaptability to application scenarios:

　　Surface mount TF cards are widely used in embedded systems such as in car systems, medical equipment, industrial controls, wearable devices, and high-end toys that have strict requirements for size and durability. These systems typically require storage media with high stability, reliability, and compact design. In contrast, traditional SD cards are more suitable for consumer electronics products such as smartphones, tablets, and digital cameras, which typically do not require strict volume and durability requirements for storage media like embedded systems.

　　In summary, the patch type TF card has significant advantages over traditional SD cards in terms of size and volume, insertion and removal durability, seismic and vibration resistance, physical protection, and adaptability to application scenarios. These advantages make surface mount TF cards an ideal storage solution for embedded systems and compact devices.
