When doing mobile cell phone repairing, you will often have to clean several points and connectors. Cleaning of points and connectors is done to clean and remove dirt and oxides from solder joints, PCB circuit tracks and the PCB itself. These dirt and oxides (often copper oxide and carbon oxide) act as resistance and hindrance to flow of current thus affecting the performance of the mobile phone handset.
Tools Needed to Clean Mobile Phone Points and Connectors:
- ESD-Safe Brush
- IPA solution or any other PCB cleaning solution or chemical.
- IPA dispenser.
- PCB cleaning buds.
- PCB holder.
