How do I repair the WiFi antenna on a Surface Go?

Question

How do I repair the WiFi antenna on a Surface Go? I believe I destroyed the antenna during the removal of the screen from the frame. There seems to be a remnant of copper foil on a short polymer ribbon.

Answer 1

On Surface Go devices, the Wi‑Fi antennas are integrated into the antenna deck assembly that sits under the display, and they are not designed to be individually repaired once damaged.

If the antenna was torn or its copper foil/ribbon was destroyed while removing the screen, the supported repair is to replace the full antenna deck (or the full chassis assembly, depending on what is damaged), not to patch or re-solder the antenna itself.

For Surface Go 4, the documented process is:

1. Power off the device and fully discharge the battery, disconnect power and all cables.
2. Follow ESD precautions before opening the device.
3. Remove the display using the documented display removal procedure.
4. Remove the antenna deck by taking out the six PH0 screws and lifting the deck out of the chassis. The original deck is retained only if it is to be reused; in a damage scenario it is replaced.
5. Install a replacement antenna deck from the correct CRU kit:
   • Place the new antenna deck over the front camera.
   • Install six new MS16030I640 screws with a PH0 driver, tightening in the specified order until snug, then an additional 45° turn.
6. Reinstall the display using the documented display installation procedure.
7. Power on and run the Surface Diagnostic Toolkit (SDT) from USB to validate Wi‑Fi and other functions.

If the chassis or battery assembly was also affected, the documented “Chassis + Battery Replacement Process” is used, which includes reinstalling the antenna deck and display as separate steps.

Because the antenna is part of these assemblies and relies on precise foil geometry and placement, ad‑hoc repairs (taping, gluing, or improvising copper foil) are not supported and may result in poor Wi‑Fi performance or further damage. The practical path is to obtain the correct CRU kit for the antenna deck (or chassis + battery, if required) for the specific Surface Go model and follow the official replacement procedures.
