Product model: Flash Disk

2, then according to the chip model: AU6983 information to go under the corresponding AU6983 mass production tool software, and finally with "Taiwan Electric U disk au6983 chip production tools. RAR" This tool mass production success.

3, pay attention to the mass production tool software before opening, first the U disk dial down, the equivalent production tool software open, and then plug the U disk, Taiwan Electric disk au6983 chip production tools can be automatically recognized. Direct point to start. The mass production process is about 7-15 minutes. At the beginning of a few minutes did not see movement, thought failed, but dare not move, the result waited about 5 minutes after the movement.

4, if you want to set, you will be vid = 17EF PID = 3852 to fill the U disk information up.
