Microsoft Band 2 defective battery connection/ribbon Replacement

はじめに

This is a (pretty involved!) guide to completely removing & replacing your rubber strap, and repairing the power ribbon inside, to restore the connection to the battery. I don't think this guide is as good as the one I posted at https://band2repair.wordpress.com/, which has more room for commentary and images.

This repair is RISKY; it could ruin your Band 2. I only did it because my Band was unusable/ruined already, and there are no replacements available so it would be junk anyways.

Carve away *almost* all of the rubber of the straps. (Leave the rubber surrounding the battery/heart rate clasp end.)

Partly dissassemble the battery clasp end: pry up the silver clasp face that is taped down, unscrew the four T3 Torx , remove that cover, remove the battery

手順3

Remove the plastic 'sandwiching' the ribbon as it travels into the clasp end, with a Dremel or knife. (Picture 2 illustrates the removed plastic.)

編集

手順4

Sand the ribbon to expose the conductors on both sides. Be careful to keep the insulator in between the two conductors intact, so they don't short. The second picture shows a 10x image of the layers of copper and insulator.

Wrap the repaired break with insulating tape. Sand away outer insulator on both sides to make soldering locations for jumper strips.

編集

手順6

Use Sugru to wrap/stabilize the repair and integrate it into the clasp end's rubber.

編集

手順7

Drill two holes into clasp-end plastic tabs, and two holes on each side of watch face's 'shoulders', as anchor points for thread to fasten strap leather. (Hole locations are the black dots on the gold metal near the silver casing.)
