Hello, I was wondering where you found the stencil for the the u2800 chip from the A1708 board from you post here:

SOLVED - 820-00840 A1708 shorted U2800

No water damage, this board was not powering up because it had PP0V9_TBT_X_SVR and PP3V3_TBT_X_S0 shorted to ground. Removed R5640 to isolate PP3V3_S0 and board powered on fine and charged great but obviously no usb Data or HDMI output. I replaced U2800 with a preballed one and put back R5640...

Hi! so sorry I just saw the notification for you message.
I found the stencil on Aliexpress: https://fr.aliexpress.com/item/4000...o2fra&spm=a2g0o.order_list.0.0.21ef5e5bdEpWLG
The guy sells also the chip preballed, while i was ther i took a stencil and a chip. The chip didn't work... Took an original from scrap board and it worked.
