One very challenging repair, we had this week was this 2018 model A1706 Macbook Pro. It is the new generation USB-C type Macbook pro which is not turning on and needed a repair.

Water damage was the reason why this lovely Macbook had a sudden death. Literally within a couple of hours after water spilled on the keyboard, Macbook was completely unresponsive.

The issue we had with this model was that it was completely unresponsive after spilled water. We could see that the USB-C chips were responding, causing the charging ports to loop but not to engage with the charger.

We took the bottom cover off and could see the traces of the liquid around the left USB-C controller. For this model to engage with the charger and allow charger voltage to reach 20V all of the 4 thunderbolt USB-C controllers need to be able to communicate with each other.

In this case one of them was faulty and was not engaging with the charger. Thankfully we were first place customer brought it for repair, so we could see the liquid traces around one of the controller chips. Otherwise, it would have been difficult to identify which one of 4 is faulty.

Repair Process

We have spotted a green spot of oxidation straight away once we removed the cover. After careful cleaning, the area revealed its secrets.

There were damaged traces and completely corroded capacitors and IC chips that fall off the board, nowhere to be found.

There was so much loss of traces in the area that there was no place to solder the new components. All pads were completely missing. We knew that we are on to something very difficult to repair here.

We have sophisticated equipment in our workshop with high accuracy microscope, ultrasonic cleaning bath, reflow machine and tools for micro soldering to achieve high-quality logic board repairs. With hundreds of components in stock, we can quickly locate and replace faulty chips, resistors, and capacitors in Macbooks.

Although it was difficult we’ve managed to retrace every trace using 0.1mm copper wire. Just for a reference human hair is 0.05 – 0.1mm in thickness.

It was a difficult job, we admit. But it was a challenge we were up for, as we knew that the new logic board for this Macbook is in the range of 1000$.

Let’s not forget also that the only way data can be accessed on these Macbooks is if the Macbook is fully operational. Apple decided to solder the SSD drive straight on the Macbook since 2018 making even simple task of data extraction from dead Macbooks impossible. Thank you Apple for ruining such a great product!

This customer was turned away by Apple Genius Bar and other shops, for a repair deemed impossible. The last step was to cover the resoldered area with a UV solder resist mask (the green blob) so it can be protected from oxidation and external factors.
