What details to pay attention to when customizing a USB drive, learn through Unikeyic!

Users have always paid attention to the customization of USB drives, whether as gifts or souvenirs. When customizing a USB drive, it is necessary to ensure its quality. Therefore, we need to be clear about which details can affect the quality of the USB drive. Considering that many people are not familiar with the internal structure of USB drives, we will now refer to the disassembly knowledge shared by unikeyic to popularize how to customize USB drives to ensure quality.

3.0 USB drives are mostly ultrasonic welded

When we plan to purchase or customize a USB drive, we can find relevant guides on Unikeyic and also view graphic information directly. For example, many people nowadays customize 3.0 high-speed USB drives with faster read and write speeds. After disassembling them, we will find that they use ultrasonic welding technology to ensure that the internal sealing of the USB drive is strong enough. Outside of ultrasonic welding, plastic or metal decorative layers are often used.

Graphite coating and copper foil shielding

After removing the plastic decorative structure of the USB drive, we can see the inside, where the black one is covered with graphite and the copper foil layer can also be seen. These structures that wrap around the USB flash drive motherboard are mainly used to shield noise and heat dissipation. When disassembling, they need to be slowly removed, and usually do not use glue or other materials to fix them. After removing them, you can often see the entire control motherboard of the USB flash drive, which will have a running storage, such as 6MB or 8MB of running storage.

Card reader motherboard and USB chip

The running speed and user experience of a USB drive mainly depend on the core components of the card reader motherboard and USB interface chip, which are related to the memory size of the USB drive and the read/write transfer speed during use. We can not only check the parameters on the motherboard and chip, but also judge the quality of the USB flash drive from the workmanship such as soldering. If it is a new USB flash drive, we can refer to the packaging.
