Failed Type-C to 4-port USB3.1 Hub

I've tested it, but the computer can't recognize it. I don't know if it's a welding or design problem. I hope someone with knowledge can give me some advice.

The main control chip uses GL3523-OV3S1. The advantage of this chip is that it can branch out up to 4 USB3.1 Gen1 outputs. However, the disadvantages are also obvious, that is, it is too expensive and the supply is very tight.

There are still some flaws in the design, such as no external power supply. If you have the ability, please make up for it yourself.

(I tried it with the typec converter I bought on tb to convert to 4 USB ports, but it couldn’t be used when charging two mobile phones at the same time)

In addition, you can have fun looking at the 5 AMS transformers on the board, just for fun.

In the attachment, I have given the BOM list of components that can be SMT mounted. If you use Jialichuang SMT, the price should be around 57.
