W1-AT PCB stopped working
Just rebuilt my W1 with the restocked 1.6mm PCB and right after rebuilding it the PCB doesnt work at all, tried changing the daughterboard and cable to my older one and it doesnt work either. My old 1.2mm PCB works fine with the old and new daughterboard too, any help?

When you first receive them, did you test them before soldering?
My 1.6mm also just broke. It was fine a month ago now it's broken, was just sitting in it's case 
Various problems may have occurred during the rebuild process.
The first is software problems
The second is a hardware problem.
In the first case,
1. Connect with another computer.
2. Use a different cable.
3. Initialize and connect the USB driver.

In the second case,
If your power connection is not grounded, the W1, which is an aluminum case,
can cause static electricity, which can cause a fatal impact on the PCB.
Or the copper foil or circuit pattern of the pcb may be damaged during the soldering/desoldering process.
Also if pcb doesn't work at all, check the soldering status of the usb connector, diode, MCU, and JST connector, including the abnormality of the copper foil and circuit pattern.
Additionally, in order to prevent short circuits caused by static shocks:
Masking the usb type c terminal and the housing port hole with insulation tape or capton tape, and inserting ESD film, etc. can help prevent a short circuit due to static electricity.
