iPhone Hardware problems in one thread - Page 110 - GSM-Forum

If you get the above situation, after eliminating the battery problem first, you need to use a multimeter and some related current equipment to detect and determine which area of the motherboard is short-circuited or leaked. Since there are thousands of chips on the motherboard, even if a local area is detected, it is impossible to determine which or which chips are faulty. This requires the rosin detection method. The steps are:

1. Smoke a layer of atomized rosin on the detected short-circuit area of the motherboard.

2. Then power on the motherboard and test it.

3. The flux rosin press on the short-circuited chip will melt immediately, revealing black color.

Not sure if this is the right thread. If not, please could you move. My question is about iPhone5 that I still keep. The front glass is broken. Do you think that in 2023 someone can change it?
