First, we'll disassemble the iPhone 11, removing the screws and applying heat to soften the screen adhesive. Visual inspection is crucial in the repair process, and we'll be identifying moisture damage on the motherboard. Repairing such issues can be tricky since the device still functions except for the lack of network connectivity.

In Spain, a typical repair cost for this issue is around 150 euros, inclusive of VAT and company expenses. We'll separate the motherboard layers using specialized tools, alcohol, and foam protectors, then heat the device to 220°C to facilitate the separation process. It's essential to handle the components gently and treat them as delicately as a newborn baby to avoid further damage.

Once the motherboard layers are separated and cooled, we'll conduct a detailed microscopic inspection to identify any corrosion causing the signal loss. Cleaning and sanitizing the affected areas will help restore the device's functionality.

Investing in a high-quality microscope after a few successful repairs can significantly improve your workflow and income. We'll use a paid tool to observe the impedance of the wet components and ensure the measurements align with expected values.

Lastly, we'll reassemble the device and test it to confirm that the signal issue has been resolved. With patience and practice, you'll be able to master the skills needed for successful repairs like these.
