Here’s a quick tutorial on how to find a short, using the Freeze Spray method. In this example, I have a water damaged iPhone 6S Plus. It is not booting up & has a VCC Main Short. If you need an iPhone repaired, please contact me via Instagram @SocalDigitalRepair or send me a text: 323.813.1349
After picking off all the capacitors that looked bad, the short to ground was still there on VCC_MAIN. Using freeze spray, I was able to pinpoint the location of the short.
My DC Power Supply was set to 4V and limited to 2A. Spraying Freeze Spray on the board, then touching ground & VCC_MAIN w/ the probes, I was able to locate the source of the short. After removing Chestnut, which had corrosion under it, I cleared the short!
