Yup, those resistors are 33ohm 0201s, and the caps are 1uf 6.3V 0402s.

No way to remove or reflow the ASIC chip and not reflow the caps and resistors surrounding it. The large pads on the bottom of the chip sink heat to the board too well to be able to heat it up to the melting point and not melt the solder on the surrounding components.

Have some dead Bitmain 17 series hashboards or full miners?
I'll buy them ... send me a PM with what you have and I'll make you an offer!

I can order the 33ohm 0201s in low quantities ok. On the caps, Digi is 10,000 minimum and Mouser is out of stock - is there another reliable source I may be overlooking? Might try the shield, in addition to laying some 3M thermal protective tape down next time. Some make it look so easy.
