I just got in a spot welder to replace a battery on my first Iphone 11 this week.[br]

After spot welding the output voltage was 0.[br]

It sorta seemed like i was too rought on the flex where it bends, so i soldered a jumper wire around the elbow of the flex from + to +, and the - i needed to make a jumper to the - Lead of the battery... Fewf, got cutomers phone working....[br]

I seen in one video not to spot weld directly on top of the circuit board as the heat can damage the board? [br]

Is this true? Is it important to unfold the tabs before spot welding?[br]

Hoping to figure this out before i attempt more batteries.[br]
