MacBook Pro A2338 liquid damage repair for a beginner?

[dbuergi]

Hi all,

i have a A2338 with water damage on the logic board. Cleaning it showed some heavier corrosion around U7000 and surrounding caps. Some are totally broke.
I get 5,2v when using both USB-C Ports but until now i didn't make any more tests.
Since i'm a beginner i want to know next possible steps. I'm not afraid replacing the intersil 9240hi but the other parts with 1mm or 2mm scare me and i don't know where to get replacements.
I fixed other laptops but this ist my first apple device .

Hi. Highly suggest to purchase some donor boards for training on soldering and removal of such tiny WLCSP packaged parts like this intersil 9240hi.

The intersil 9240hi is available from Aliexpress.

Hello mons2,

thank you for your reply. Do you have any tipps for tools to work on these parts? As stated i worked on boards and have a hot air station, soldering irons and a digital microscope. Would it be easier to use low melt solder or solder paste for such small parts?

looking at what's going on around the isl, everything under the isl is corroded! before buying a new isl, reball the old isl! you have all the tools! buy a stencil right away, if not, for the isl and soldering paste for rolling the balls and flux! this will be enough to replace it and all the other components!
